Fixed Pressure CPAP Machines
Fixed pressure CPAP machines use one pressure setting delivered throughout the night (i.e. 8cm/H2O). These standard CPAP machines are used to treat obstructive sleep apnea, sleep disordered breathing, and snoring. Is fixed pressure CPAP better than auto CPAP? There is no clear cut answer because both devices treat the same sleep issues and it comes down to a matter of preference. Some users prefer to sleep on the same pressure through the night and auto users prefer the automatic adjusting feature of variable pressures. It should be noted that fixed pressure models do not offer auto mode however auto CPAP models can be set to auto or fixed pressure mode.
