RE: Anyone Using Philips BiPAP AVAPS C Series Mod #1160P?
Vaughn;
Thank you for your reply.
From the old machine data printout:
90% of the time device EPAP pressure was <= 8.3 cm
90% of the time device pressure support was <= = 8.5 cm
average pressure support 5.0 cm
I had an overnite oximetry study on the old machine:
<90% 5.1%
<89% 2.3%
What do you think of these numbers?
At the present time the Dr seems to be chasing AHI. Your comments about SpO2 seem logical and the recording Pulse Oximiter also seems logical. I'm an engineer so I like to get data that I can see. I will bring this up with my Dr the next time I talk to him. I also hope jedimark64 can update SleepyHead to read my new machine data.
Thank you for your help.
Regards, Jim G.

When considering lowering the amount of Pressure Support (in case the Min PS setting may be too high and causing the average SpO2 to be higher than 96%), I think it is the median SpO2 statistic (how high is the SpO2 at least half the time while using the new machine) which would be of greater interest, instead of how low the dips were going during apnea events on your old machine.
Your 90 percentile EPAP pressure was lower on your old machine than the EPAP setting on your new machine, so I think it seems unlikely that your present EPAP setting is too low and somehow is contributing to the occasional large increases in Pressure Support, but in the perhaps unlikely chance that somehow it is, perhaps it would be helpful to make sure you will never be rolling into the supine position, flat on your back, which is usually the position most likely to cause or make worse our obstructive events.
But what I think would be most likely to help would be to get the type of recording Pulse Oximeter which is comfortable enough to wear multiple nights a week, so you can monitor your SpO2, which may allow the target tidal volume to be safely lowered, leading to less PS being needed.
