The large breaths after the OA in the image above would be described by some as "arousal breathing". Its a fair description. There would be some kind of EEG arousal after the OA and 'gasping' to get more air when the airway opens again. "gasping after an OA" -> arousal. Without the OA it could just be turning in bed.

Here is an arousal from last night. A very slight diminished flow rate, then a gasp and a CA. An arousal IMHO.

For those with low ahi but daytime fatigue symptoms, did the switch to BIPAP result in a lower index # and improvement of symptoms?

Bump. Anyone?

It seems there is a correlation between the resp rate, tidal volume and pulse graphs but also times of divergence. What do you look for in these charts?

Your question, "It seems there is a correlation between the resp rate, tidal volume and pulse graphs but also times of divergence. What do you look for in these charts?"

Minute ventilation (normal can range a lot - maybe from 5 to 10 liters per minute - it depends on the height of a person to calculate their lung volume) = resp rate (#breaths in 60 seconds) x tidal volume (amount of air in each single breath in ml).  

Minute ventilation is more key IMO, because it needs to stay relatively stable.  

Resp rate (usually 12 to 20 per minute is average during sleep) and tidal volume (very rough numbers are 400 for a female and 500 for a male) can vary some; and when one goes up, usually the other goes down to compensate (and keep minute vent steady). 

When apnea events occur, heart rate can rise to compensate.  

Also, hyperventilation can occur when minute vent gets too high (and heart rate rises as well).
