Does high PS increase central apnea?

Thanks

It can. So can running in auto mode. Just depends on the individual. Thus the need for proper use of long-term trending data while changing one thing at a time, once obstruction is being prevented.

It can. It really depends on an individual level. Also, for example, a PS of 3 may possibly be high for someone with OSA, but for someone with significant lung disease it may possibly be low. A PS of 3 for me is suffocating.

Technically speaking (according to my undersanding anyway), practice standards do not usually consider a PS of 3 to be true bilevel therapy at a recommended level. Four cmH2O is considered the minimum recommended PS for bilevel and 10 cmH2O is considered the maximum recommended PS, despite the fact that bilevel machines can be run at other settings.

"4.3.1.3 The recommended minimum starting IPAP and EPAP should be 8 cm H2O and 4 cm H2O, respectively, in pediatric and adult patients (Consensus) . . . 4.3.1.6 The recommended minimum IPAP-EPAP differential is 4 cm H2O and the recommended maximum IPAP-EPAP differential is 10 cm H2O (Consensus)" -- Journal of Clinical Sleep Medicine, Vol. 4, No. 2, 2008.
