Trigger Setting Switch - Aircurve 10

[MrIvanDrago]

So last night I lowered my trigger setting from 'High' to 'Med' to see if the CA's would appear or if I would be able to go back to the default settings. 

Question: Could this impact apnea events in any way? I had my highest AHI score ever last night, and none of the events were CA's. I find this interesting and wondering thoughts on how this trigger setting could affect events in general, not just CA's. For reference, I typically have an AHI under one and been using a bilevel for 7 months now, CPAP for a year prior.  Any insight would be great. Thanks.

My understanding is that a higher trigger can expand the period of inhalation pressure support, which could decrease obstruction.

I agree with G. Szabo's analysis.  Your OA's are very clustered together; like you put yourself in a certain position for a short period of time that caused this cluster.  Have you ever tried a soft cervical collar?

I'd agree this was positional. Clustered events and high flow limits. I don't think the trigger setting is the culprit here.

[MrIvanDrago]

Definitely looks like a positional thing, but I was curious about the trigger setting and the high amount of events the same day I changed the setting. I'll try again tonight and see if it was just a coincidence with the position I was sleeping in last evening. Thanks all!
