So, i finally got my S9 auto bipap, on loan for 3 weeks free, $375/month if I need it longer.
I tried it for 20 minutes and it aggravated my back injury ::frownie::. After 10 days to recover, I am going to try again.
I ran into a problem when I tried it before, which kept me from sleeping. I felt like i could only exhale about half the air in my lungs, with each breath. That was on IP=8, EP=4 (and on auto, but i checked the readout and it was staying at those pressures).
Every 4 or 5 breaths I would feel compelled to open my mouth, to let out the stale air that had built up in my lungs.
Is there something I am missing, something I should be doing?
If I'm lucky, this problem is also why the machine hurt my back (where my diaphragm attaches) and so I can solve both issues at once.
Thanks, always for your advice and experience!
