question
for the past several days my VT has dropped to around the 300ml range. Is there something I should be concerned with?

I unpluged the power cord from the machine and plugged it back in tonight just in case.

Thx

RE: question
Are you saying your tidal volume is low? Estimated tidal volume is a function of body mass, and varies by individual, and of curse health issues like lung disease. 300 would be pretty awful for me, but for a smaller person, and many women, just fine. What has it been in the past? An increase in PS can increase the ventilation rate, but I would not suggest changes without more information.

RE: question
it showed that number of 320 or in that range but it was the medium range that was shown on the machine. When I looked in SH it shows the 95% was close to 500.

Lesson learned that the screen doesn't necessarily say what % the number is so better to look at the full data in the software

RE: question
FWIW my average tidal volume on BiPAP at PS 4+ is over 600. On an APAP it about 100 ml less. My lung capacity is off the charts, probably because when I was a kid I used to run at high altitudes. I'm the guy everyone wants to blow up their pool raft. Smile If you are a smaller person, if you smoked, and for many other reasons your volume is going to be less, and the mid 300s is pretty healty for a lot of people. It's impossible to judge without more information.

I am using a S9 VPAP Auto not an autoset but it shows up on my ResScan V5.1.0.8731.

Best regards,
