Obstructive apneas only after disturbed/arousal breaths? - sleeplover69 - 07-10-2018 Looking through my Mom's SH charts, I see she gets OSA events only after breathing spikes and almost nowhere else. Really strange, but she sleeps like a rock though. Are these really OSA? What's going on here? CA to contrast RE: Obstructive apneas only after disturbed/arousal breaths? - yrnkrn - 07-10-2018 Without effort belts you can't really know. My guess these very short apneas are post-arousal CAs and that the machine is wrong. Your mom can take a HST, for this purpose it's ok. RE: Obstructive apneas only after disturbed/arousal breaths? - sleeplover69 - 07-10-2018 Thanks. My first thought was that they are wrongly flagged. Anyone else here get these? What is HST in this context? RE: Obstructive apneas only after disturbed/arousal breaths? - tedvpap - 07-10-2018 It is not clear to my untrained eye. Even if they are actually CA due to arousals, it is not clear what is causing the arousals. Since the events are flagged as OA, and it looks like the prior struggle may be due to expiration, I would increase the EPAP and see if it helps.
