The goal of airway humidification is to maintain and support the normal physiological environment in the airways. Healthy individuals breathing in ambient air, e.g. 22 °C, 7 mg/L, warm and humidify the air to an average of 31 °C, 32 mg/L with nasal breathing at the pharynx and 37 °C, 44 mg/L in the lung1.
Patients on noninvasive ventilation (NIV) breathe at much higher pressures and flows than normal. They often have compromised airways, due to the nature of their respiratory failure,2 and are less efficient at warming and humidifying gas.3
The F&P 810 Humidification System is designed to deliver physiological humidity, with the aim of making noninvasive ventilation (NIV) a more comfortable experience, increasing tolerance and avoiding complications.
Bypassing the natural humidification systems in the upper airway, for example with a tracheostomy, means that a patient’s airways become less efficient at warming and humidifying gas. Bypassed airways result in impaired sneeze and gag reflexes, meaning that the principal remaining line of airway defense is the mucociliary transport system.
The F&P 550 System is designed to deliver Optimal Humidity (37 °C, 44 mg/L), with the aim of preserving mucociliary function and mimic the physiological levels of humidity in the lower airway.
