VPAPauto PS -#101

[zzzZorro]

Can someone give a #101 explanation of just how changing the PS affects various things/issues when in the VPAPauto mode?

I know it sets the spread of EPAP and IPAP but what else does it accomplish?

Thank You

In VPAP auto, pressure support can be used to treat flow limitation and hypopnea, relieve some of the respiratory effort and improve respiratory volume. This is part of the normal titration protocol. Pressure support is both a comfort feature, making breathing easier, and a therapy feature, specifically targeting certain types of events. In your case, PS is limited by the degree to which it increases CA. The Vauto has no backup function, so it is not used to provide a backup breath.

Thanks SR.  I wasn't going to post for awhile and instead do some experimenting (an obvious pastime in many arenas).  I have found S-mode to be the least productive and focused again on Fixed and Auto.  First thought auto might be inducing some problems but now I am not so sure.  I have zeroed mostly into the first 20 or so minutes of transition into sleep where clusters of apneas frequently appear.  I tried a setting bonjour suggested (10-22 PS=2) last night and got a chart reflecting exactly this.  First cluster was at beginning of sleep and then awakened with very dry throat and trying to fall asleep the second time.  

Now I am trying to figure out if this phenomena on the pre-sleep is just "ME" and always going to be there or if juggling these settings (possibly starting with PS) could effect lead-in. Then there is apparently the possibility that over time my brain could dial these out maybe?  With this setting breathing was most comfortable.
