Treatment-Emergent Central Sleep Apnea. Current trendy term for (usually) relatively high x PAP pressures in susceptible individuals (see Loop Gain). You could also probably use SleepHQ and effectively present your case. Note above. It would appear that 8.0 cmH2O is "relatively high" in your case. ...

2) So, why can't he just use my OSCAR reports...... because he can't "trust" a consumer software program that has not passed scrutiny of the hospital. (reluctantly, I see his point) His "point" is "go away, you bother me" But, if he wants to be an ass, then get a copy of ResScan™ which is Resmed's ...

It's not? OPPS, your quite correct, that is an image I posted a year ago. In response to that image I got a private message from another forum member who suggested that I eliminate the EPR and lower the max pressure to 15 to try to avoid the very abrupt increase in pressure and consequence that may...

It was the cardiologist who directly poo-poo'd the OSCAR report, and specifically made the analogy to a smart watch, IIRC saying something like just because the smart watch reports sleep stages and oxygen doesn't qualify it to be considered a serious medical device. The sleep MD had a bit of a diffe...

I'll try to answer each question: @Pugsy; Is your doctor aware of these periods of Cheyne Stokes Respiration? Yes @Miss Emerita: Make an appointment with your doctor soon, and show him or her several samples of these flagged waxing/waning episodes. Print them or take your laptop. The level of zoomin...

Interesting that you should ask. I pointed out these Cheyne Stokes episodes to my cardiologist and he said to discuss it with my sleep doc. In general, he seems to be dismissive of testing that is not conducted by certified-creditable labs. "You have no indication of heart failure"- his words. When ...

How long do those periods last?

Resmed IDs these Cheyne-stokes lasting 23 to 45 minutes.

I've had discussion with my doc previously and I came away with this understanding. Home Cpap machines do the best they can to approximate the AASM guideline for hypopneas, but because the home machine does not measure oxygen saturation, they have to rely on reduction in flow to identify hypopneas....

And anyway tidal volume is based on a 5-breath average. Since an event can occur with a change in only one or two breaths, the rolling average probably wouldn't even drop enough to score an event. With an 8 second short term ventilation window a 5-breath average is worthless. Less than worthless. L...

You still have a much bigger problem than 'are these 'real' hypopneas?

You mentioned that earlier, but didn't say what the bigger problem is. Can you tell me now?

Yeah, I debated about “more restrictive” and “more liberal”, and decided it depended on the point of view. Regardless, we are understanding each other.
Per your suggestion, I’d best be doing some shopping and or cooking.
So…… Merry Christmas for now.

Anyway, and TTBOMK, the long-term (baseline) window is 100 seconds (excluding any apneas or hypopneas); the short-term window (event) is 8 seconds; the reduction criteria for a hypopnea is 50%; and flow imitation must be present in order to score a hypopnea. Rubicon is describing the real Resmed ru...

A bit of research: https://i.imgur.com/zXut4ms.jpg The overall cost of administering benefits for traditional Medicare is relatively low. In 2021, administrative expenses for traditional Medicare (plus CMS administration and oversight of Part D) totaled $10.8 billion, or 1.3% of total program spendi...

https://i.imgur.com/bqVOxtZ.jpg Do you see what I mean? Is the comparison segment the prior 10 seconds, or 20 seconds, or 30 seconds or something else? I'm assuming that the segment marked as hypopnea is averaging the volumes measured in that segment. In this case it would be max =477, min = 361 an...

As an example: This Airflow identified, as a >30% reduction is compared with what segment of the preceding breaths https://i.imgur.com/BZ2b4WK.jpg I don't see a tidal volume chart there. Ahah, have I been looking at the wrong plot ? Once I get a chance to , how far back do I need to look for the co...
