Humidity is Vital

The respiratory system is a highly balanced mechanism reliant on humidity.

Clinical efficacy is significantly improved by emulating the balance of temperature and humidity that occurs naturally in healthy adult lungs. Bridging the gap between artificial breathing systems and a normally functioning airway ensures greater benefits for patient and clinician.

To provide therapies that maintain optimal lung function, it is necessary to understand the physiological balance of humidity in the normal airway.

3 KEY BENEFITS OF HUMIDIFICATION
1 Assisting natural defense mechanisms in the airway
2 Promoting efficient gas exchange and ventilation
3 Increasing patient comfort and tolerance to treatment
 
 

The Normal Airway

The normal airway has two main lung functions: to maintain efficient gas exchange, and to preserve airway defense. To function optimally, natural balance must be maintained.


Two Main Lung Functions


Gas Exchange
Air-flow to the alveoli is necessary for gas exchange. The natural heating and humidifying functions of the airway assist with maintaining clear and patent airways by promoting mucociliary clearance and reducing bronchoconstriction associated with airway cooling.

Airway Defense
Primary mechanical defense mechanisms are sneezing, coughing, gagging and the use of natural filters, i.e. nasal hairs. The second line of defense is the mucociliary transport system which traps and neutralizes inhaled contaminants (in mucus) and transports them up and out of the airway, keeping the lung free from infection-causing pathogens. This critical defense system is very sensitive to humidity.

Humidity is also crucial to mucociliary health.

 

Complications of Interventions

When a patient enters the hospital environment and requires respiratory support, the natural balance of the airway can become compromised.
