AHI 6.4 last night. I woke up about 3 AM and I could feel the relief from my legs to my knuckles. Still a long way from feeling great, but a big improvement over recent nights.
I'll keep these settings tonight.

I do agree with this. The M series APAP mode will let you set minimum to maximum so that it will function like a cpap with a fixed pressure but will give you Flow Limitation data in apap mode....FL data is turned off in cpap mode so the 0.0 FL reports don't mean a thing in cpap mode.
I don't know if NR index is turned off in cpap mode...never checked into that part of things but the NR index wasn't high in the past in APAP mode...so I think it is a non issue anyway...but it would be nice to have the FL data.

It would appear that NRAH Mode would also need a range of pressures that would allow the machine to scout for NR-iveness:

Above 8 cmH2O pressure, the pressure increase for sustained apneas/hypopneas is limited to 3 cmH2O above the pressure setting at the onset of the apnea/hypopnea sequence. The pressure setting at the onset of the sequence is called the Onset Pressure. The pressure 3 cmH2O above the Onset Pressure is called the NRAH Threshold. NRAH is an acronym for Non-Responsive Apnea/Hypopnea.
An apnea/hypopnea x2 event detected after reaching the NRAH Threshold is considered to be non-responsive.

When the device encounters a non-responsive apnea or hypopnea, it will decrease pressure by 2 cmH2O and hold the pressure for 15 minutes. During this 15-minute NRAH-hold period, the pressure will be changed only in response to detection of a sequence of vibratory snore events. The reason for this increase in pressure followed by a decrease in pressure when an apnea/hypopnea is not responsive is to allow the device to respond appropriately to an event that is not treatable by increases in pressure, such as a central apnea.

Thanks mollete. I didn't know that little tidbit about the NR index determination and response was tied in with pressure drops.
Never really read up on it very much long ago because NR flags were very rare for both myself and other reports that I saw.
When I asked respironics rep about NR and centrals...I was told that they got lumped in with the OAs and hyponeas when they were sensed and not in the NR basket where I would have though they might have gone. So really didn't investigate any further.

I will try to remember this but you know if I don't use it I lose it. And I don't get to work with many M series reports anymore.

Oops! I forgot about that......I did know about it, but it's been a long time since one of these discussions that it slipped my mind.

Thanks Dave.
