[CPAP] Why's AirSense 10 purporting to ramp up from 13 to 20, without spewing more air?

[StackExchange]

Please watch this video, taken while I wore my nasal pillows. As 13 cm H₂0 is my normal air pressure, why's AirSense 10 lying about automatically ramping up to 20 cmH₂0, without in fact spouting more air?

My sister, brother, husband replicated this glitch, while wearing my nasal pillows. None of us felt any increase in air pressure, as AirSense allegedly ramped up. Is my 3-year-old AirSense broken?

There are two explanations.  Your machine can go to 20 but only does so when needed.  Also, you have yours set to stop at 15, and it won't go higher than you set it.  There is no problem with your machine.  It's working as it is designed to.

You could order a cpap manometer to measure pressure. Not much we can offer with just a recording of the screen

You don't need a manometer. Your machine is fine.
