Airsense 11 Noises on Inhalation? Normal?
Airsense 11 Noises on Inhalation? Normal?
Hello, I just purchased a New Airsense 11 from a DME company. I wasn't sure if this noise is normal when inhaling or indicative of an issue. 


Also when I breathe a large breath into the mask it makes this sort of vacuum noise I wasn't sure if was normal either. Using the Airfit F20, tightly secured with a good seal as far as I can tell. Filter is properly placed. EPR looks like it was turned on and set to 3 if that makes a difference, using the heated tube.
