Resmed Adapt ASV question
#1
I have been using the Adapt for a while now, it is the only machine that I could tolerate. However I am still not getting good sleep and have been doing some research on Tidal Volume and Respiratory rates.

Some of the reading I have done leads me to wonder if it is possible that the Adapt is forcing me to breathe at a higher rate than would be natural for me.

For instance I often wake up in the night, on the machine, and find that I am breathing rapidly. The next morning I feel light headed like I have been hyperventilating.

Does anyone know if the algorithm of the Adapt has a set breath per minute rate? I have read some users of ASVs write about training the machine to follow their breath, is this what I should be doing?

Any thoughts??

I'm more a fan of averages than medians, but everything I see in your attached file looks so normal it's nearly boring. There is nothing unusual about any of the stats. If anything the 95% and maximum pressure support looks pretty low for your type of machine.

The machine should follow your breathing rate, unless you are in a central apnea (not breathing) in which case it should follow a back up rate and prompt you to breathe with levels of pressure support determined by the machine.

It looks like your epap is fixed at 6. The file didn't show any apneas, but shows "total time in apnea" of 3:27. What type of apneas are you experiencing?

Shots in the dark: (1) You could switch to ASVauto with a narrow epap range to see if epap goes anywhere to treat obstructive apneas. (2) increase maximum pressure support a little to provide more central apnea treatment. Of course, talk to your doctor first.

As I understand it the VPAP Adapt only reverts to a backup rate if you have a central apnea (as mentioned above). My breathing is fairly slow (10 bpm) but the machine never tries to hurry me, except occasionally during the sleep/wake period.

If the machine is trying to force the pace, blow back hard when it's forcing you to inhale. The sudden powerful exhalation seems to "reset" the algorithm and the machine reverts to a less intrusive mode. Otherwise, just relax and breathe slowly but evenly and the machine will "learn" and adapt to your breathing pattern.

As an aside, I had a PR system 1 Bipap ASV for a while and it definitely was a fight every night. The Resmed is like a soft embrace in comparison. Other people have had the exact opposite experience.
