Answer: The Airing device has been designed so as not to require active humidification. The human nose has evolved to filter the air it breathes in through a pathway with tiny hairs and to humidify this pathway with every exhalation. This system works well if the normal tidal volume is exchanged. When excessive air is blown continuously into the nose, the entire pathway can dry out and become quite uncomfortable; this is not natural breathing.
Traditional CPAP machinery requires a motor and a fan or blower cage to blow large volumes of air down a hose and into a mask or nose pillow. The inertial mass of the motor/fan/blower assembly and the length of hose prevent the rapid (instantaneous) adjustment of the air flow to respond to the actual breathing cycle. BiPAP and APAP systems do have the ability to reduce the total amount of air being pushed at the patient during exhalation, but only to a limited extent.
The Airing device will have built-in pressure sensing and will be able to adjust the micro-blower output instantaneously. This ability to respond to where a person is in the breathing cycle eliminates the need for excessive air flow. This allows more natural breathing and mitigates or may even eliminate the need for additive active humidification. Passive humidification is possible if desired.
