I don't think your sleep study is particularly useful if you didn't sleep well, and your OSCAR data is more useful at this point.  The AHI is good, but your pressure is all over the place, increasing on flow limits. Those same flow limits have a SIGNIFICANT effect on your SpO2. Getting those back under control will improve your sleep, especially if we work to avoid the CA events you initially had.

On the question about the F20 elbow, that white packing is to reduce noise and has nothing to do with filtering the air. It is not replaceable on its own, the whole elbow would be replaced routinely.

Your VAuto therapy isn't too bad, but you might need a bit more Min. pressure as it's now at 4. Eventually I'd think the PS needs to come up if you were attempting to avoid CA by this method. Your FL/flow limits are likely affected by the 0 PS.

And the oxygen is showing dangerously low as OSCAR shows a very low 79%. If accurate, you need to address this with the doctor. At 88% for over 5 minutes and doctors are filling a script for supplemental oxygen. So keep a sharp eye on it.

It will be set by default at Medium.  I assume you know how to access the settings menu by pressing the control knob and home button at the same time?  A "high" trigger setting makes the machine switch to inhale pressure a little earlier with less inspiratory effort. This sometimes reduces the incidence of CA events by stimulating a spontaneous inhale.

well, as an atrial fibrillation patient I would beg to differ.

First,yes, your oxygen levels are very low and may be related to your heart palpitations, so definitely do something about that.

New onset atrial fibrillation often occurs at night during sleep. Apnea is one of the few understood triggers for atrial fibrillation. And yes your palpitations may be entirely benign. Usually in your situation a 24 or 36 or two week long Holter monitor would be prescribed. this measures your heart activity 24/7 for a given period of time. People don't know what their hearts are doing when they're asleep. More, some issues only occur randomly once or twice a month. So a 24 hour Holter monitor will only record what your heart is doing in that period (as anEKG only records what your heart is doing for the minute during which it was recorded.) these Holter type monitors are simple, painless and cheap for a doctor to administer. I really advocate getting a two week monitor, or at least a week, so you have a better sense of what's going on.

Cardiologists are the "plumbers" of the heart; Electrophysiologists (EP's)are the electricians. Irregular heart beats are usually the provenance of EP's. Cardiologists will often not want to acknowledge this.

You may want to press your cardiologist for the Holter/ Zio patch.l You won't even have to go in to see him or her. It can be done by a nurse. Super easy-peasy.
