ResMed ASV maintains a constant Minute Volume to manage Central Sleep Apnea.
My understanding of your May 24 Oscar report, specifically between~ 0607 and ~0625, the patient initiated (triggered) about 4-6 breaths out of what might have been an expected 100-150 breaths. However, the ASV took charge and supplied the missing breaths.
So, technically YOU stopped the normal breath cycling, but because the ASV made up the difference so that your system would still maintain oxygenation..... so you wouldn't die.
Is that normal, you not initiating the respiration cycle at that frequency?
IMO, No, it is not normal, and that is why your treatment/therapy requires ASV.
Most sleep therapists and RTs do not fully understand the seriousness of Central Apnea and end up prescribing inappropriate or ineffective treatment, such as putting the patient on regular CPAP therapy which in turn exasperates the patient's central apnea.
Most often this ignorance towards Central apnea is because CSA patients make up a small percentage of the apneac population or sometimes simply because the patient's insurance does not cover ASV treatment.
Another point that I have been making here is the fact that even when Central Apnea is correctly diagnosed and a ASV system is prescribed (currently and as far as I can tell, only Philips and Resmed offer ASV systems for home use), professionals still need complete data sets from each sleeping session, in order to continue with intelligent and effective therapy.
For example, my Philips Respironics ASV logs details of machine triggered breaths, down to timestamps for each event (see below).
It is NOT normal for anyone to stop breathing for such long periods of time while asleep and thus besides Phrenic Nerve Stimulation Surgery, ASV ventilation therapy is the only known form of therapy for to this group.
