I know that’s what is in the manual, but I disagree. X0 is just Philips CYA setting for masks that they aren’t responsible for. It also stacks the deck in favor of their masks.

The X setting compensates for the pressure drop in the mask. If it is too low, you may feel air-starved, like breathing through a straw. If it is too high, it will feel like the machine is overcompensating: as you begin to inhale, you may feel slammed by a whoosh of extra air. Either way, it is introducing a mismatch between the targeted and actual pressure.

Try both, and use whichever feels more natural when breathing.

All masks have a pressure drop that is proportional to the airflow (just like the hose). At zero flow, that doesn’t matter; the pressure at the sensor will be the pressure in the mask. The flow is never zero though due to the vent holes and of course breathing.

When air is flowing, the pressure drops in series stack up: bacterial filter (if present), hose, HME (if present), and mask. As flow increases, so does the pressure difference between the sensor and the mask.

X0 makes total sense from a product liability perspective. It is absurd from a physics/engineering perspective unless you are just sticking the end of the hose in your mouth.

From a dead space perspective, you should use whatever the nasal pillow setting should be, as the Bleep has very little dead space.

Then should it x1 or x2?

I contacted the DME, was told the setting is x1.
