An Overview of Humidification Mechanics

by with No Comment HumidifierUncategorized

Humidification plays a pivotal role in respiratory care, especially within the context of mechanical ventilation. Ensuring optimal humidity levels is essential not only for patient comfort but also for safeguarding the respiratory tract and enhancing ventilation outcomes. The mechanics behind effective humidification are designed to mimic natural airway conditions, compensating for the absence of the upper airway’s natural humidifying functions. Understanding these mechanics helps clarify why maintaining ideal humidity levels is so critical for both acute and long-term respiratory support.

Importance of Humidification in Ventilation

Humidification is critical in mechanical ventilation for several physiological reasons. First, it prevents the drying and damage of airways. When gases are delivered during mechanical ventilation, they bypass the upper respiratory tract, which naturally warms and humidifies air. Without humidification, the cold and dry gas can dry out airways, leading to discomfort, irritation, and potential damage to the mucosal lining (1,2). This prolonged exposure can cause secretions to thicken and increase the risk of airway blockage.

Second, humidification is vital for maintaining mucociliary function. The respiratory system’s mucociliary escalator relies on a well-hydrated mucus layer to trap and remove particles and pathogens. Adequate humidity keeps the mucus moist, allowing cilia to move it effectively out of the airways. In contrast, without sufficient humidity, mucus thickens, resulting in secretion retention and a heightened risk of infection (3).

Moreover, proper humidification reduces the risk of atelectasis, where mucus plugging obstructs the airways and compromises lung function. By preventing thick secretions, humidification helps maintain open airways, optimizing ventilation and oxygenation. It also aids thermoregulation by minimizing water and heat loss through the respiratory tract, thus preventing hypothermia and dehydration, especially in patients requiring prolonged ventilation.

Enhancing Patient Comfort and Breathing Efficiency

Humidified gases enhance patient comfort by preventing dryness in the mouth, nose, and throat, which is crucial for those on long-term ventilation. Furthermore, it reduces the risk of respiratory infections by maintaining moisture in the airways, promoting pathogen clearance, and minimizing the formation of stagnant mucus, which can harbor bacteria (4).

Finally, properly humidified air decreases airway resistance, easing the effort required for breathing. This is particularly important for critically ill patients or those on ventilators, as it facilitates better gas exchange and reduces the work of breathing (5,6).

In summary, humidification is essential to maintaining respiratory function, protecting the airways, and enhancing the overall outcomes of mechanical ventilation. It significantly improves patient comfort and reduces the risks of complications associated with long-term ventilator use.

Overview of Humidifiers and Ventilators

Mechanical ventilation and humidification are essential components in respiratory care, particularly for patients requiring long-term respiratory support. Ventilators deliver oxygen to patients, and humidifiers are used to ensure that the air provided is moistened and warmed, simulating the natural humidification process of the human body (7-10).

Types of Humidifiers for Ventilators

Humidifiers used in ventilation fall into two categories: heated humidifiers, which actively heat and moisten the air delivered by the ventilator, and heat and moisture exchangers (HMEs), which capture moisture and heat from exhaled air for reuse during inhalation.

  1. Heated Humidifiers (Active Humidification)
    • These devices actively heat and add moisture to the air delivered by the ventilator, providing optimal humidification levels.
  2. Heat and Moisture Exchangers (Passive Humidification)
    • Also called “artificial noses,” these devices trap the moisture and heat from the exhaled air and reuse it during the next inhalation, offering an easier and less energy-invasive method of humidification.

Heated Humidifiers

Heated humidifiers are devices designed to add moisture and warmth to the air delivered by mechanical ventilators to patients. This is essential because mechanical ventilation bypasses the body’s natural mechanisms for humidifying and warming air, which are usually done by the nose and upper airways. Without proper humidification, dry, cold air can irritate and damage the respiratory tract.

Heated humidifier

Key Components of Heated Humidifiers:

  1. Water Reservoir/Chamber:
    • Contains water that is heated to generate moisture.
  2. Heater Element/Heated Plate:
    • Located under the water reservoir, it heats the water to produce warm, humidified air. The heating element can be adjusted to achieve the desired temperature and humidity level.
  3. Temperature Sensors:
    • Sensors monitor the temperature of the gas at the humidifier outlet and adjust the heating to ensure optimal humidification and prevent overheating.
  4. Heated Wire Circuit:
    • The ventilator circuit (tubing) often includes heated wires that help maintain the temperature of the humidified gas as it travels through the tubing to the patient, preventing condensation (rainout).
  5. Control System:
    • Modern humidifiers are equipped with control units that regulate temperature and humidity based on patient needs, ensuring precise control over the humidification process.

How Heated Humidifiers Work:

Heated humidifiers work by heating water in a chamber to create water vapor, which is then mixed with the gas flow from the ventilator. As the gas passes over the heated water, it picks up both moisture and heat. This warm, humidified gas is delivered through the ventilator circuit to the patient’s lungs, with heated wires in the tubing helping to maintain the temperature and moisture content along the way.

This ensures that the gas remains at an optimal level for the patient’s comfort and respiratory health. The temperature at the airway is typically regulated around 37°C, mimicking body temperature, to prevent cooling and condensation in the tubing. The humidifier continuously adjusts its heating to strike the right balance between temperature and moisture for effective respiratory care (11-13).

Benefits of Heated Humidifiers:

Heated humidifiers offer several key benefits in respiratory care. They prevent the drying of airways, which can lead to irritation, excessive mucus production, and airway obstruction. By providing proper humidification, they help keep mucus thin and mobile, reducing the risk of mucus plugging that could result in atelectasis (lung collapse) or infection.

Heated humidifiers also maintain body temperature by delivering air that matches the body’s natural warmth, minimizing the risk of hypothermia, which is crucial for critically ill patients or those on long-term ventilation. Additionally, they enhance gas exchange by supporting the normal function of the lungs and respiratory system, leading to improved oxygenation and ventilation. Finally, they significantly improve patient comfort by delivering warm, moist air, preventing dryness and irritation in the airways (11-13).

Applications of Heated Humidifiers:

  • Invasive Mechanical Ventilation:
    • Heated humidifiers are commonly used in patients on invasive mechanical ventilation, such as those with endotracheal or tracheostomy tubes. These devices bypass the upper airway, eliminating the natural humidification processes of the body (12).
  • Non-Invasive Ventilation (NIV):
    • In non-invasive ventilation, such as Continuous Positive Airway Pressure (CPAP) or Bi-level Positive Airway Pressure (BiPAP), heated humidifiers are often used to enhance comfort and maintain airway moisture (12).

Challenges and Considerations:

  1. Condensation (Rainout):
    • One of the common challenges is condensation within the ventilator tubing, which can occur when the humidified air cools down as it travels through the circuit. This “rainout” can lead to water accumulation in the tubing, which may disrupt ventilation and increase the risk of infection. Heated wires in the circuit help mitigate this issue by maintaining a constant temperature.
  2. Infection Risk:
    • Heated humidifiers require regular cleaning and maintenance to prevent bacterial growth in the water reservoir. The use of sterile or distilled water is crucial to minimize the risk of contamination.
  3. Energy Consumption:
    • Heated humidifiers require electrical power to maintain the heating element, making them more energy-dependent than other forms of humidification like heat and moisture exchangers (HMEs).
  4. Monitoring and Adjustment:
    • Regular monitoring is needed to ensure that the humidity and temperature are set at appropriate levels, tailored to the patient’s needs (17-21).

Comparison with Other Humidification Methods:

  • Heat and Moisture Exchangers (HME):
    • Unlike heated humidifiers, HMEs are passive devices that trap moisture and heat from the patient’s exhaled air and return it during inhalation. While they are simpler and do not require power, HMEs are less effective in long-term ventilation or for patients with high minute ventilation.

In conclusion, heated humidifiers are essential for ensuring optimal humidification and temperature control in mechanically ventilated patients, especially in critical care settings. Their ability to provide warm, moist air helps prevent complications associated with dry airways, improves patient outcomes, and enhances overall comfort.

Heat and Moisture Exchangers (HMEs)

Heat and Moisture Exchangers (HMEs), also known as “artificial noses,” are passive devices used in respiratory care to conserve moisture and heat in the breathing circuit of mechanically ventilated patients. Unlike active humidifiers, which add heat and water vapor to the air, HMEs capture and reuse the patient’s own exhaled heat and moisture to humidify the inhaled air.

HMEs

Key Components of HMEs:

  1. Core (Moisture Retaining Material):
    • The core of the HME is made of hygroscopic material (e.g., paper or foam) coated with salt or other substances that retain moisture and heat.
  2. Filter:
    • Some HMEs include a bacterial or viral filter to trap pathogens, offering additional protection against infections.
  3. Housing:
    • The outer shell is typically plastic and designed to fit into the ventilator circuit. It connects between the endotracheal tube or tracheostomy tube and the ventilator tubing.

How HMEs Work:

During Exhalation the warm, moist air passes through the HME. The hygroscopic material in the HME absorbs moisture and retains the heat from the exhaled air.

During Inhalation the air passes back through the HME. The retained moisture and heat from the exhaled air are transferred to the cool, dry inhaled air, warming and humidifying it before it reaches the lungs.

This cycle repeats with every breath, continuously maintaining humidity and temperature within the respiratory system (23).

Heat and Moisture Exchangers

Types of Heat and Moisture Exchangers (HMEs):

  1. Simple HME:
    • These HMEs passively trap heat and moisture from exhaled air without any active warming or humidification. They are inexpensive and widely used in short-term ventilation.
  2. Hygroscopic HME:
    • These HMEs use special materials, such as calcium chloride, which enhance moisture retention from exhaled air. They offer better humidification compared to simple HMEs.
  3. Hydrophobic HME:
    • Made from water-repellent materials, these HMEs focus on capturing heat rather than moisture. They also help reduce bacterial contamination by acting as a filter.
  4. HME with Integrated Filters:
    • These devices incorporate bacterial/viral filters to trap pathogens, offering a dual function of humidification and infection prevention.

Benefits of Heat and Moisture Exchangers:

Heat and Moisture Exchangers (HMEs) offer several benefits, particularly in terms of simplicity and convenience. They are easy to use, disposable, and require no power source or complex setup, making them ideal for short-term or emergency ventilation situations. HMEs are also cost-effective compared to heated humidifiers, with less need for maintenance, which makes them suitable for temporary or non-invasive ventilation.

Additionally, because they are single-use devices, HMEs reduce the risk of cross-contamination and eliminate the need for continuous cleaning and sterilization, unlike heated humidifiers that require regular disinfection. Their lightweight and portable design also makes them highly practical for non-invasive ventilation (NIV) and patient transport scenarios (24).

Limitations of HMEs:

Heat and Moisture Exchangers (HMEs) have several limitations, particularly in high-demand respiratory situations. Their efficiency decreases in patients with high minute ventilation, where large volumes of air need to be humidified. This can lead to airway dryness, mucus plugging, and lung complications. Additionally, excess moisture can cause the HME to become saturated, resulting in increased resistance, potential blockage, and reduced effectiveness in delivering humidified air.

HMEs are generally intended for short-term use, typically up to 48 hours, making them less suitable for long-term ventilation where heated humidifiers are more effective. They also add a small amount of dead space to the ventilator circuit, which can increase the work of breathing, especially in pediatric or neonatal patients.

Furthermore, HMEs are less effective in certain clinical situations, such as with patients who have thick or copious secretions, and are not recommended for those requiring high levels of humidity or oxygen, such as patients on high-flow oxygen therapy (23-25).

Applications of HMEs:

  1. Invasive Mechanical Ventilation:
    • HMEs are commonly used in patients on invasive ventilation, particularly those who require short-term ventilation in settings like the operating room, recovery rooms, or emergency departments.
  2. Non-Invasive Ventilation (NIV):
    • HMEs are also used with NIV devices such as Continuous Positive Airway Pressure (CPAP) or Bi-level Positive Airway Pressure (BiPAP) systems. They help improve comfort and maintain airway moisture in patients using masks for ventilation.
  3. Post-Surgical Care:
    • In post-operative settings, HMEs are useful in maintaining airway moisture for patients recovering from surgeries, especially in cases where mechanical ventilation is required for short periods.
  4. Home Care and Transport:
    • HMEs are favored in home care settings for patients on ventilators due to their simplicity and low maintenance. They are also commonly used during patient transport, where active humidifiers may not be feasible.

Comparison Between HMEs and Heated Humidifiers:

AspectHeat and Moisture Exchanger (HME)Heated Humidifier
MechanismPassively conserves moisture and heatActively adds moisture and heat
Power RequirementNo power requiredRequires electrical power
Humidity ControlLess precise; relies on patient exhalationPrecise control over humidity and temperature
EfficiencyLess effective in high minute ventilationHighly effective for long-term ventilation
CostLow, disposableHigher cost, requires regular maintenance
Infection ControlSingle-use, minimizes contaminationNeeds regular cleaning to prevent infection
ApplicationsShort-term, low-risk ventilationLong-term ventilation, critically ill patients

In conclusion, Heat and Moisture Exchangers (HMEs) are valuable tools in respiratory care, providing a simple, low-cost method for humidifying and heating the air in mechanically ventilated patients. While they are highly effective for short-term or low-ventilation needs, they have limitations in long-term or high-minute ventilation scenarios. For patients requiring prolonged ventilation, heated humidifiers may offer better humidification and temperature control.

history of global pandemics and epidemics

Introduction: The Impact of Pandemics on Humanity Throughout History

A little over four years ago, the world was reminded once again of the frailty of life, illness, death, global disease, and global disruption by the COVID-19 pandemic. Words like quarantine, lockdown, pandemic, social distancing, hand-washing, sanitizers, and isolation, among others became a part of our day-to-day language. The impact of the most recent pandemic was far-reaching worldwide. The social, emotional, economic, and political disruption felt in the wake of the COVID-19 pandemic is starkly reminiscent of the generalized impact associated with pandemics and epidemics from time immemorial.

Pandemics and epidemics have always been a part of human history, and they remain so as the COVID-19 pandemic proved just recently. Pandemics and epidemics of flu, cholera, malaria, and HIV/AIDS are still a part of daily living across the world. From medieval times to the present time, humans have lived with disease causing organisms, and human disruption of the social and biological strata often leads to infection with some disease causing organisms, with increased industrialization and globalization leading to the eventual spread beyond the initial area of contact. 

Pandemics and Epidemics are used to show the extent of the spread of infectious and non-infectious disease conditions, with the difference being the extent and area of spread. To help understand the difference between epidemic and pandemic, it is crucial to also understand some key public health terms such as outbreak and endemic. An outbreak refers to an unexpected increase in the number of people with a particular health condition or the spread of a health condition in a new area. Endemic means that the health condition occurs at an anticipated rate in a geographical area. An epidemic is an outbreak that spreads to a larger geographical area; meaning an unexpected increase in health conditions or new cases of a health condition across larger geographical areas. Pandemic is an epidemic that spreads across continents globally.1,2

From Ancient Times To The Middle Ages: Historical Pandemics

Pandemics have been around since ancient times. Some of the pandemics recorded in history from ancient times to the Middle Ages include:

  • Athenian Plague: This occurred between 430-26 BC during the Peloponnesian war between Athens and Sparta.3 Originating from Ethiopia and spreading throughout Egypt and Greece, the initial symptoms were headaches, conjunctivitis, body rash, and fever followed by later symptoms of hemoptysis (coughing out blood), stomach pain, vomiting, and eventual death in most people.3,1 The war led to the rapid spread of the disease and was marked by the mortality of about 25% of the city’s population, despair, and breakdown of law and order.3, 1
  • Antonine Plague: Also known as the ague of Galen, it occurred between 165 – 180 AD in the Roman Empire.1 It was transmitted into the Empire by soldiers returning from war, spreading to a larger geographical area including Asia Minor, Greece, Egypt, and Italy.4 About 33% of the population or 5 million people including Marcus Aurelius, the emperor, died of the pandemic.4,3 Symptoms were rashes, fever, pustules, and bloody diarrhea.1,3 It is thought to be part of the factors that led to the downfall of the Roman Empire.
  • Justinian Plague: Named after Justinian 1, the Byzantine emperor at that time, the plague caused by Yersinia pestis occurred in 541 CE ravaging the Roman world and beyond.5 Hallucinations preceded other symptoms such as fever; cough fatigue; buboes in the groin, armpit, or behind the ear; lethargy, and eventual death.3,1 Between 5,000 – 10,000 people were thought to have died daily in Constantinople, and total death from the plague is estimated to be between 25 – 100 million.4,5 The emperor himself was infected, but he didn’t succumb to the plague.5 The plague resulted in food scarcity, starvation, economic instability, breakdown of law and order, and a stop in the military conquest of Rome.5,3

The Black Death: Also known simply as the Plague, it is thought to be the most fatal pandemic in human history. Originating from China in 1334, the plague spread across Europe, Asia, and Africa and was caused by the bacterium Yersinia pestis.6,1 Symptoms included fever, chills, fatigue, vomiting, buboes.2 The Plague is thought to have claimed 75 – 200 million lives and wiped out about 30% of Europe’s population. 2,4,1 Economic instability, the emergence of the middle class, the breakdown of law and order, antisemitism, turmoil, widespread destruction, food scarcity, and starvation were some of the aftermaths of the plague.6

New World and Eurasia Pandemics

The European exploration of the Americas known as the Columbian Exchange resulted in the exchange of more than just food, animals, plants, ideas, and population. Disease exchange was another important tradeoff. Prior to the invasion by the Europeans, the Native Americans had no contact with diseases that affected Eurasia such as smallpox, whooping cough, malaria, influenza, typhus, diphtheria, and chickenpox, hence; they had no immunity to the diseases.7,8 

In the years after the exploration, these diseases became epidemic in the New World (The Americas). The mortality rate in various villages, cities, and towns was as high as 80%, and 90%, and in some cases, entire populations such as the Taino people were wiped out and became virtually extinct.8

The massive loss of human lives led to disruption in ecosystem as forests grew rapidly and animals increased.9 Economically, labour shortage ensued and also led to the Transatlantic Slave Trade establishment.9

Industrial Revolution and Pandemics in the Modernization Process

The 18th, 19th, and 20th centuries heralded huge development in industrialization, modernization, and technological advancement. Rise in infectious diseases, and resultant pandemics and epidemics were also part of this development. Notable among these are the cholera pandemic, the Spanish flu, and the Asian Flu. 

Asian Flu: This was caused by the H2N2 influenza virus in 1957 which originated from China.4 It spread to the United States of America, Hong Kong, England, Scotland, and Singapore within months.1, 4,11 The estimated death toll during the pandemic is between 1 – 2 million. 1,4,11 

The Seven Cholera Pandemics: Caused by the bacterium Vibrio cholera, and spread through the fecal-oral route, the cholera pandemic was formerly endemic to Asia until 1817 when it spread from India to other parts of the world in what is known as the first cholera pandemic.2,10 Advancements in transportation systems aided it’s rapid spread. Subsequently, five other cholera pandemics occurred between 1827 to 1923. During the third cholera pandemic, the physician John Snow was able to trace the source of the outbreak to contaminated public water2. The seventh cholera pandemic began in 1961, and it is thought to be ongoing.1 The cholera pandemic led to sanitation emerging as a public health measure.2, 10

The Spanish Flu: The 1918 Spanish flu pandemic started in Kansas and was spread by troops.1 The H1N1 of avian origin was the cause of the Spanish flu, and symptoms were cough, fever, weakness, malaise, and nose bleeding in some mild and severe cases.1, 3 Personal hygiene and quarantine were the major public prevention health measures put in place during the pandemic.1 

Asian Flu: This was caused by the H2N2 influenza virus in 1957 which originated from China.4 It spread to the United States of America, Hong Kong, England, Scotland, and Singapore within months.1, 4,11 The estimated death toll during the pandemic is between 1 – 2 million. 1,4,11

Global Pandemics and Epidemics in the Modern Era

In modern times, pandemics and epidemics still continue to be a big part of our lives. Viruses majorly affecting the respiratory system have led to several epidemics and pandemics in the modern era. The HIV/AIDS pandemic is also another modern pandemic that humans still grapple with. 

  • The HIV/AIDS pandemic: In the 1980s, scientists first discovered the Human Immunodeficiency Virus (HIV) in the United States of America.3 It spreads through contact with body fluid such as blood, and breast milk, and through sexual intercourse and from an infected mother to her unborn child.11 HIV attacks and weakens the immune system, especially as it progresses to AIDS (Acquired Immune Deficiency Syndrome) if left untreated.11 The HIV/AIDS pandemic affects people across countries and populations, and it is more prevalent in Sub-Saharan African countries. Worldwide, HIV is thought to affect about 40 million people.3,11 It is one of the pandemics that has received widespread attention from local, regional, and global public health institutions and pharmaceutical companies in terms of research, funding, and treatment.1
  • SARS: The Severe Acute Respiratory Syndrome (SARS) was caused by the severe acute respiratory syndrome coronavirus (SARS CoV), and it originated in China in 2003 spreading to 29 countries.1,2 Case identification, contact tracing, isolation, and surveillance were the public health measures used in containing the spread of the pandemic.1
  • MERS: Middle East Respiratory Syndrome (MERS) was caused by the Middle East Respiratory Syndrome Coronavirus (MERS CoV) which was first reported in Saudi Arabia.1,2 Symptoms include cough, sore throat, fever, and chills and those above 65 years are more likely to have severe disease.2

COVID-19 Pandemic: New Pandemic Challenge of The 21st Century

Spreading from Wuhan, China to the rest of the world faster than earlier pandemics, the COVID-19 pandemic showed how swiftly pandemics can spread in this era owing to improvements in transportation, technology, and globalization. The COVID-19 pandemic is caused by the Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2). The Coronaviruses belong to the family Coronaviridae, and there are four genera which are alpha, beta, gamma, and delta. The SARS CoV, MERS CoV and the SARS-CoV-2 are all in the beta-coronavirus genera.2 
Dry cough, fever, fatigue, malaise, rhinorrhea, headache, shortness of breath, nausea, vomiting, diarrhea, and loss of sense of smell (anosmia) were some of the symptoms of the pandemic. 1,2,4 The COVID-19 pandemic led to a lot of public health measures. Isolation, quarantine, physical distancing, use of face masks, appropriate coughing etiquette, case identification, contact tracing, border closure, closure of public gathering sites, stay-at-home orders, movement, and transport restrictions were measures put in place by different countries to curb the pandemic. 2,11 Subsequently, vaccines were also produced and approved for use.

Social, Economic, and Political Impact of Epidemic Diseases

Pandemics and Epidemics are known for the enormous disruption they wreck on every life facet. Some of the impacts include:

Death, loss, and grief: High mortality rate means that survivors might be thrown into grief and survivor’s guilt. Distress could also set in.1,2,3

Financial and Economic Impact: Labour shortages when death tolls are high during pandemics have been recorded. Starvation and food scarcity are also economical effects of pandemics. 1,10 During the COVID-19 pandemic, public health measures put in place such as restricted movement; lockdowns; closure of public gathering centers such as schools, and religious institutions; and border closures; affected trade, livelihood, and the economy. 2,4,5

Social Impact: The breakdown of law and order was associated with earlier pandemics.1,3 Physical distancing during the COVID-19 pandemic restricted movement and social gatherings.2

Political Impact: Social unrest could also lead to political instability. For example, the Antonine Plague is thought to be one of the factors that led to the downfall of the Roman Empire.1,3 

The burden on the healthcare sector: The healthcare system takes a huge toll during pandemics. Healthcare workers become overburdened, equipment is used rapidly and needs to be produced just as fast, and medical ethics dilemmas set in.1

Global Responses and Preventive Strategies Against Pandemics

Strategies to prevent pandemics have emerged in the face of combating them. During the Black Death, quarantine surfaced as a means of curbing the pandemic.1,2,3 Also, the Cholera pandemic led to the public health prevention measure of Sanitation.1,2,3 The COVID-19 pandemic led to increased global preparedness for pandemics. Vaccination is another key preventive measure pandemics have brought about. The SARS-CoV pandemic utilized contact tracing, isolation, surveillance, and personal hygiene.1, 2The COVID-19 pandemic saw public health and pharmaceutical companies on their toes as vaccine, medication, and public health measures to curb the pandemic were put in place.1,2,3, 11
Lessons Learned From Pandemics Throughout History

Man’s disruption of ecological strata, climate change, and increased contact between humans and animals have been found culpable in pandemics.1,2,3,11 Also, globalization aids the rapid spread of diseases.10 Preventive measures such as hygiene, use of masks, and cough etiquette have been learned and continue to stay relevant.1,2,3,11

Global health surveillance of new infections has also received a lot of attention. Strategies for curbing spread such as quarantine, border closure, movement restriction, case identification, and tracing have also been learned.1,2,3,4,11 Institutions globally are now paying more attention to public health. More funding, research, and commitment are given to the health sector. The pharmaceutical industry has also rapidly evolved and become swifter in producing medications and vaccines as evidenced by the last pandemic.2,1,11

Conclusion: The Lasting Effects of Pandemics on Humanity

Pandemics, especially the last one have heightened and tightened public health measures and reminded everyone that a pandemic is never far away.1,2 Global health institutions and pharmaceutical companies have seen a lot of improvement in dealing with pandemics as the COVID-19 early vaccine production and strict public health measures showed.1,2,3,4 Preparation for the next pandemic is given to every individual, country, health institution, pharmaceutical sector, and global health institution.

Heated and Humidified High Flow Oxygen

What is the Role of Heated and Humidified High Flow Oxygen In Respiratory Support?

by with No Comment HFO

Generally, there are two common ways of administering oxygen therapy. One of these is the high-flow device method like air entrainment masks or non-rebreathers. While the other known as low-flow devices use nasal cannula or masks. Many a time, the high-flow nasal cannula are often administered during surgical procedures. Evidence also suggests that this humidified oxygen therapy is safer at a stand-alone surgical IMCU. 
Therefore, why is heated and humidified high-flow oxygen (HFNC) necessary for respiratory support? Continue reading to know more.

Heated and Humidified High Flow Oxygen

Understanding Heated and Humidified High-Flow Oxygen Therapy

High-flow oxygen is a respiratory therapy that supplies oxygen at a significantly higher rate. It is a medical device that usually serves as a breathing support for ICU patients. Additionally, it delivers oxygen continuously through a tube inserted into the nostrils. This ventilation supply often aids patient comfort, because they are always humidified and warmed to 37°. 

On most occasions, this therapy is mostly used to treat patients experiencing respiratory distress. Also, heated and humidified high-flow oxygen therapy is always provided if standard oxygen therapy isn’t working. Hence, it helps lessen the effort your body must expend on breathing. Apart from reducing respiration effort, it also produces slight positive pressure in the upper airways.

How Does Heated and Humidified High-Flow Oxygen Work?

Unlike conventional low-flow oxygen, HFNC delivers its maximum oxygen rate beyond 30 L/min. Also, this High-flow oxygen isn’t merely a regular nasal cannula but one that’s increased extremely. However, there are some key steps in which heated and humidified high-flow oxygen is produced. Some of these are:

  1. Oxygen Heat-Up: In most cases, HFNC always heats oxygen to the same temperature as the body. Furthermore, they often provide 37 degrees Celsius of air during inspiration.
  2. High flow of gas: Additionally, this breathing support works by providing oxygen gas (FiO2) at an elevated inflow rate. It supplies about 1.00% fiO2 at up to 60 liters per minute of flow.
  3. Provides Humidified Air: Because high-flow therapy is often administered at a high standard, the gas is always humidified. Therefore, inhaled air often contains moisture that is the same as normal air.
  4. Supplied through Device: Just like any other assisted ventilator, this ventilation support is also supplied via devices. Also, depending on the patient’s fiO2 requirement, the delivering device might be nasal cannulas or masks.
Heated and Humidified High Flow Oxygen

Indication for Using Heated and Humidified High-Flow Oxygen

Sometimes, when standard oxygen therapy fails to improve low oxygen levels, HFNC may be used. In most cases, this heated and humidified high-flow oxygen is often used to support patients experiencing respiratory distress. Nevertheless, some of the breathing issues that always indicate high-flow oxygen usage are as follows:

  • Congestive heart failure
  • Respiratory distress syndrome (RDS)
  • Non-small cell lung cancer (NSCLC)
  • Bronchial asthma
  • Bronchopneumonia
  • Pulmonary edema
  • Intensive phase of Chronic obstructive pulmonary disease (COPD)
  • Broken ribs and other types of chest trauma 
High-Flow Oxygen

Benefits of Heated and Humidified High Flow Oxygen in Respiratory Care

When compared to traditional oxygen therapy, HFNC offers numerous advantages. They are known as a heated and humidified system that enables easy flow of oxygen. In addition, the fraction of inspired oxygen (fiO2) can be regulated at an extreme inflow rate. Therefore, what are the benefits of high-flow oxygen for patients with respiratory disease?

Accurate Oxygen Distribution

In normal circumstances, the oxygen delivery rates of HFNCs are usually higher than those with traditional nasal cannulas. As a result of this, there is always a limited room air retainment. Besides, it also provides a high amount of oxygen that overcomes the patient’s peak inspiratory flow rate. Therefore, it doesn’t dilute the oxygen wished to give a patient. 

Improves Functional Residual Capacity (FRC)

By supplying a varying amount of positive pressure, high-flow therapy also affects the FRC rate. This is often determined by the placement of manometers at the posterior oropharynx. On most occasions, the readings of this pressure are not always very high during closed-mouth breathing. However, when patients open their mouths, the impact nearly disappears. Additionally, research indicates that the application of HFNC readily results in a 25% improvement in FRC.

Dead space Clearance

Additionally, with heated and humidified high-flow oxygen breathing is usually more efficient. Why? This is because the continuous high oxygen flow often eliminates anatomical dead spaces present in the airways. In addition, the warm, heated air always assists with mucus and foreign particles and also reduces the energy for breathing.

Humidified Oxygen

Comparing Heated and Humidified High-Flow Oxygen to Traditional Oxygen Therapy

When comparing high-flow oxygen to traditional oxygen, several differences and similarities can be extracted. However, some following points indicate the similarities of both systems.

  1. Most of the time, both devices supply FiO2 at a variable concentration
  2. They also serve as respiratory support
  3. Neither traditional oxygen nor HFNC are delivered in the invasive mode
  4. In most cases, they are simple to administer and easily adjustable
  5. Either of the two systems can be used effectively in similar clinical conditions e.g. COPD cases, acute respiratory failure etc.

Although, heated and humidified high-flow oxygen provides some similar functions to traditional oxygen. Hence, this high-flow device also has some specialty when compared to the low-flow. Some of these significant features are:

  1. The ability to provide oxygen gas at a very high rate that ranges between 30 to 60 L/min
  2. Capacity to actively moisturize inflow air
  3. Provision warm oxygen that complies with body temperature
  4. Prevent airway problems and complications by maintaining and clearing respiratory dead spaces
  5. HFNC is also more effective at improving oxygenation, especially in hypoxemic patients.

Considerations for Implementing Heated and Humidified High-Flow Oxygen

Normally, heated and humidified high-flow oxygen is easy to use. Nonetheless, some integral factors must be considered while implementing this device. Hence, I would like to give you some basic “DEDEVUS” processes that must be considered while using HFNC.

  • Determine your patient condition and device compliance rate
  • Ensure a proper setting of the system: You must make sure the high-flow device is in good form. Additionally, thighs like the flow rate, FiO2 level, filter, battery, and ventilation slot should be examined thoroughly.
  • Don’t place a patient on high-flow oxygen immediately after the device is turned on.
  • Examine your oxygenation channels: It’s very important to verify the O2 tube connection and adjust flow to prevent FiO2 delay and regulate the flowmeter. In addition, ensure to set your internal alarm menu and avoid smoking.
  • Verify humidification supply: Things like sterile water, plastic bags, and caps should be checked thoroughly. Also, the water bag must not be empty and the permeable circuit must be monitored at every interval.
  • Use the appropriate tube and cannula with the correct placement
  • Set alarm 

Future Directions and Innovations in Heated and Humidified High-Flow Oxygen Technology

In the modern world, almost every aspect of life is gradually evolving. Some of these have led to several innovative improvements in the medical world and assisted ventilation to be precise. Hence, heated and humidified high-flow oxygen isn’t left aside. Also, most scientists believe they are one of the best and most dynamic mechanical ventilation systems. Therefore what are high-flow oxygen future trends? 

Be informed that several innovative directions of HFNC are yet to be seen. However, some of these potential features and trends, such as precise delivery, flexibility, patient compliance, personalized treatment, etc are expected to emerge soon.
