2.8. How does the waterless humidification compare with AirSense 10
humidification?
Our waterless humidification system allows exhaled air to pass through the HumidX before it reaches
the mask's vent. In typical overnight conditions* this helps ensure minimal heat and moisture loss and
allows HumidX to deliver a similar level of humidification as a traditional bedside device.**
*In a typical overnight temperature of 16-22°C and a dry room of 20-30% relative humidity, the
HumidX provides humid air 70-80% RH to breathe.
**When compared to a AirSense 10 with a humidifier setting 4 and a SlimLine tube.
2.9. What should I do if my patients are not getting adequate
humidification?
The HumidX performance is impacted by mask leak and therefore is more suited to low leak users. In
order to maximise humidification for your patients, we recommend first trying to minimise any leak.
If the HumidX is still not providing the desired level of humidification try swapping between the
HumidX & HumidX Plus to see if this improves comfort levels for your patient. It is advised to consider
the patients environmental sleeping conditions as variability in ambient humidity can impact the
performance of the HumidX.
If neither of these options help, waterless passive humidification may not be suitable for the patient's
humidification needs.

2.10. Is there humidification for full-face masks?

No. ResMed currently provides waterless humidification for N20 and P10 for AirMini only.
Using the current HumidX technology we are unable to develop a HME for full faced masks that can
deliver the desired level of humidification performance. We are currently researching next generation
HME technologies that we hope will allow us to develop a HME for full faced masks with the desired
humidification performance in the future.
2.11. How come the HumidX lasts for 30 day when HMXs have to be
canged everyday in the ventilation devices?
Heat and Moisture Exchangers are commonly used for short durations for patients with high
dependencies (e.g. patients with tracheostomies) due to increased breathing resistance (impedance
of HME), bioburden loading and humidification efficiency.
The use of the HME in a CPAP masks differs as CPAP patients retain the use of their upper airways
which contain defence mechanisms for contaminants and support additional humidification of inspired
air.
Furthermore, the implementation of the HumidX away from direct contact with the airway significantly
reduces effects of blocking or contamination which lead to flow restrictions. These factors enable
increased longevity of HMEs within the CPAP (non-invasive) use case.
