Hypothetical question for the gurus
I wonder if we could set up an Aisense 10 to perorm a simple check on how many AHI's someone has in a night WITHOUT the help/therapy to avoid them.
I understand that this will in no way replace a sleep test.
I just want to wear my mask and see how many AHI's I would have in a night pretending I am not wearing it.
Can it be done? If yes, what are the settings?
RE: Hypothetical question for the gurus
Straight CPAP 4 is the closest. It might still offer some amount of therapy, so it's definitely not ideal.
Mask Primer
Positional Apnea
Attach OSCAR, etc.

If I were to set my machine at 4cm CPAP mode, I would expect a report to reveal my severe sleep apnea AHI as was shown by my in-lab sleep studies. I once reduced it to 8cm CPAP and got a report showing moderate sleep apnea AHI. My therapy setting is APAP Min 12.6 cm. I consider each sleep session report as an abbreviated sleep study.
It would be interesting to know at what pressure level an in-lab or home sleep study begins.

No, this isn't possible in a reliable way. Setting the machine to pressure of 4 will make many adults air starved and not simulate what it would be like to breathe naturally, and setting it to a higher pressure is going to prevent events that would happen not on CPAP but you won't know how many.
RE: Hypothetical question for the gurus
I wonder at what pressure setting a sleep lab starts that 1. does not air starve them. and 2. causes the least apneas. I recall there was pressured air to the mask. Maybe it was cm 1 to begin the study, AHI was established, then pressure was increased until OAs and such were resolved?
I won't try it but I suspect using CPAP 4cm would produce a severe apnea AHI report for me.
With too low-pressure settings, some get the same AHI as their sleep study.

RE: Hypothetical question for the gurus
Something that I tried really early on was simply using an oximeter (4% ODI and/or 3% ODI) to estimate the severity of my sleep apnea.
I have read a lot of studies on this. Some studies equate ODI as high as a 90% correlation to the AHI index. Other studies do not support this.
Anyway, if a person got a significant amount of SPO2 drops during sleep, that should be enough evidence to tell that something is wrong. And most likely sleep apnea is the culprit.

RE: Hypothetical question for the gurus
SP02 if accurate would indeed be a good source of apnea severity determination. I tried an O2 Ring (worn on a finger) product. The results were such that I don't trust that device for SPO2 accuracy, but the O2 drops did line up with apneas.
