waking up with shortness of breath although Cpap on

Hi

I wake up occasionnaly with shortness of breath knowing that my Cpap is on , this is happening not always but like once or twice a month , i checked my sleep report on both Oscar and sleepha and i noticed a gap in breathing and im wondering what could be the reason , why is it not happening everyday and why the report still shows very low AHI

i am attaching my sleepdata ( Oscar and Sleephq ) for that night.

Thank you in advance

That is a bit puzzling. You are feeling short of breath but are actually breathing more deeply. It may be useful to zoom in on that period of time. Also drag the Mask Pressure, and Minute Ventilation graphs up so they show along with the Flow and Pressure.

Could this reflect centrals?

Hi Sierra

Yes , i am concerned about the area i highlighted in red , i have attached the graph with events flag , flow rate , pressure , mask pressure just as you requested , i also zoomed in so you can see clearly , the time slot is from 21:56 to 22:03 .

I hope this will make the graph clearer this time , once again thanks for your help , i appreciate it .
