... as readily obvious in function as charts like leak rate and pressure: tidal volume, minute ventilation, respiratory rate. Read other sleep data troubleshooting threads ...

... What I see in OSCAR/SleepHQ: OA and H are well controlled. Median tidal volume 320 mL, p95 ~500–600 mL (lots of recovery breaths). Waveforms show jagged, flattened ...

Started graph when i fell asleep see how normal tidal volume and resting respirations look until 7:15 and then it gets very choppy and seems to coincide ...

... can't find where I bumped a different preference. I've lost Flow Rate, Tidal Volume,Resp. Rate, Minute Vent and Insp Time. Any clue?? I'm really trying to watch results ...

... because it appears that during REM sleep my minute ventilation and tidal volumes get really low. I have tried lowering my IPAP little by little and it appears that ...

Thanks Pugsy. You will never see a tidal volume graph from me again :D . The asleep vs awake breathing theory makes total sense. I do actually ...

Tidal volume is useless at this point. No sense in wasting graph space. Tidal volume has way to many variables that are ...

... although I guess I won't be able to do FL or snore so I just included tidal volume below instead. Unfortunately, I only have the 10S and it doesn't have Vauto mode. The ...

... do it. Can you post some examples Unstable breath flow, very unstable tidal volume. I will try your suggestion of going back to a fix pressure, I know I tried that at ...

... = 5, max IPAP = 9,and PS = 4 as a starting place.) I am looking at my Tidal volume and it seems higher then normal. For now, ignore your tidal volume. You need to focus ...

... to meet some kind of a target value for the minute ventilation or tidal volume of the inhalations. Once the inhalations are deep enough to meet that target value, ...

... a suspicion that this may be closer to auto s if you use the target tidal volume setting. From the literature this seems to react to your natural rhythm which is what ...

Have you tried s/t mode? I have a suspicion that this may be closer to auto s if you use the target tidal volume setting. From the literature this seems to react to your natural rhythm which is what auto s seems to do on the basic BIPAP machine. Would be great to confirm this either way.

... assuming that the VT is intended to be used with a target tidal volume to avoid this.....let us know how you.get on I've been playing with the t min and max ...
