Clear Airway Clusters

You might need to max IPAP limited to about 16. Also you have variable PS of 4 to 8. Your CA cluster is happening at high IPAP plus a wide split in PS.
The high split in PS may be permitting to to exhale too much CO2 upsetting the brains trigger.

It's a bit complex, so, I'd consult a sleep doc who knows their stuff.

I'm with the kind and gentle Mr. Mongo on this. Your numbers are really not too bad: AHI 4.31 overall, CA 3.59...... I think this is caused by your pressure and PS settings.

I would try the settings Mongo suggests and see what happens over the next few days.

Hi CPApnea,
WELCOME! to the forum.!

Good luck to you at your next apointment with the new sleep doc.
Much success to you as you continue and fine tune your CPAP therapy.

Based on what?

There is another, well-held opinion, that the machine is not good at all at guessing whether the CAs are real or not. And I'd expect that they aren't.

Do you have a citation for that "well held opinion."

My expectation is based on physics and math.

Terry

I'm with Terry on this. The machine discriminates between open and obstructive events by sound. A 4 Hertz, 1cm-H2O pressure wave is started 4 seconds into an event. The phase and amplitude of the reflected wave are used to determine open or closed airway. That phase and amplitude are detected by the sensors in the flow meter.

If open, the low frequency sound wave is deadened by the large lung volume that contains many branches and alveoli that dampen the reflected wave. If closed, it's in the throat, the the reflected wave has a higher amplitude and smaller phase shift due to shorter path.

I second what Mongo asked.
