I know what TV on my CPAP is, maybe you mean TV. Tidal Volume - the estimated volume of air taken in during a single breath.
Dedicated to QALity sleep.
You'll note I am listed as an Advisory Member. I am honored to be listed as such. See the fine print - Advisory Members as a group provide advice and suggestions to Apnea Board administrators and staff concerning Apnea Board operation and administrative policies. Membership in the Advisory Member group should not be understood as in any way implying medical expertise or qualification for advising Sleep Apnea patients concerning their treatment.

I think it's tidal volume written as Vt. I'll check on my machine next time I'm upstairs.

The tidal volume is the amount of air displaced with each breath, measured in millilitres. It varies depending on a whole range of factors, but around 500 mL is fairly average.

I have looked on the internet and gotten a little information on tidal volume but not enough to answer my questions so of course I come here where people know the answers or at least have some good information so if your tidal volume is below 500 Glock 380 or 400 as an example what might be the cause of that

There was a thread a couple of weeks ago where this was discussed: http://www.apneaboard.com/forums/Thread-...dal+volume I don't think it came to any clear conclusions. A lower Vt would mean you're not breathing as deeply as somebody with a larger one, or you might have a smaller lung capacity. The Vt isn't your whole lung, of course, just the amount that's exchanged on each breath.

Vaughan came up with an article and calculator which helps explain it. But I don't think there's much to worry about if you're one side of the norm or the other, provided you feel OK and your O2 reading is OK, then I don't think Vt matters too much.

Tidal volume is one half of the information required to calculate Minute Ventilation which Resmed controls in their ASV machines in order to control CAs. The other half is Respiratory Rate. The Minute Ventilation is a product of the two. It is not really important for CPAP unless one of these parameters makes a statistically significant change. If that happens it is time to seek your doctor's counsel to find out what may be happening.
