Invasive ventilation at home

Understanding home-based invasive ventilation and the important role of heated humidification

An example of an invasively ventilated patient with a tracheostomy tube and a close-up of the mucociliary transport system.

What is invasive ventilation?

Invasive ventilation refers to respiratory support delivered directly to a patient's lower airways. In a home environment, this typically occurs via a tracheostomy tube.

How does invasive ventilation affect the physiological conditioning of inspired air?

The upper airway, bypassed during invasive ventilation, is responsible for up to 75% of the physiological conditioning (heating and humidifying) of inspired air. As a result, invasive ventilation can significantly impact a patient’s ability to heat and humidify the air they inspire before it reaches their lungs.¹

The mucociliary transport system, a defense mechanism in the upper airway, strongly relies on the heat and humidity of inspired air to function optimally.

How does heated humidification play a role in invasive ventilation?

By restoring and supporting natural mucociliary clearance in the upper airway, heated humidification aids the transportation of debris up and out of the airway.*²
It allows the patient to conserve energy as the airway doesn’t need to provide additional heat or moisture to the inspired gases.* ^3,4
