flow limitation

flow limitation
Hi, like all cycles, after getting my DS1 replaced by Philips and setting my FlashAir card again, I have embarked on my Oscar dive of my performance. Generally my AHI sits between 0.8 - 1.2 and I don't typically suffer OA but rather have the greatest incidence of Flow Limitations which are typically in the inspiratory side of things. 

Just curious, is it valid to think that flow limitations are just the inception point for all (latent) hypopnea's and OA with most not manifesting due to the cpap treatment? Or should I think of them as exclusive and their own issue? And, is the incidence of flow limitations connected to Philips's Variable Breathing classification? Interested in any thoughts on this. 

thanks,
Dafod

RE: flow limitation
The problem is obstructive breathing period.
This is representative of a continuum starting with flow limits, hypopneas, and apnea.
Treatment wise we start with an air splint to hold open the airway with the target being the minimization of apnea events. Theoretically increasing pressure will treat both hypopneas and flow limitations but practically it is the differential pressure between inhale and exhale, EPR in your case, that does a better job of this.

Thanks. I increased my EPR to 2 the other night and it helped a little.

RE: flow limitation
OK, you may want to try EPR 3 if your Min pressure is at least 7 to gain all pressure differential benefits.
