Help for the clueless

Watched videos on leaks and modified the settings on the cpap (thank you Respirator99). Still struggling with the seal on the nasal mask (an odd toucan-beaked-shaped face). Taped the mouth. Not successful in uploading oximeter data to Sleephq.

You have a handle on the leaks... good job! But that desat around 12:39-47am (ring time) is not good... did your arm go to sleep?

The ring time and machine time are off from each other. Along with the 1 hour offset I think the times are skewed... that desat looks like it should correspond with the period of low respiration rate given from 11:31 to 11:38 (machine). Looks like the ring is 52min slow.

So please check your pulseOx and machine clocks for both accuracy and sync. Otherwise out of my depth here, but either your parms need tuning or you need more than an ASV... you hit a low resp rate of 6.2.

Yes, thank you for reminding me. My arm did go to sleep. Those finger oximeters are prone to getting "bumped" and shutting off so I sleep with my arm in an odd position.

Yes, I see this now, the clocks seem to be off. Maybe low respiration rates are something others on the CPAPtalk frequently see when transitioning from awake to sleep?

I don't understand what your picture has to do with your statements. I went through my Oscar graphs and I do show some low peaks, nothing like the continued episode you showed.

Again, I'm not a doctor but I really want to know exactly how wrong the clocks were on your devices... and sleeping with your arm in a bad position just to keep a device turned on seems counter-productive... what device are you using?

Here's my respiration rate for the last three months, interested to see something like this for you recently.

I fixed the clocks (off by an hour or so). To the untrained eye (me) your OSCAR respiratory chart (thank you) looks similar to mine (with some of your low numbers of "3" or "4" on March 3rd). Still trying to figure out how to interpret all this data.

Again, I wanted to know *exactly* how off the clocks were. Never mind.

Your daily rates show lots of zeros and max below half of mine. Time for someone else to try. Good luck.

The clocks are correct now and the O2 levels imported to Sleephq. (sorry, took me a while to figure all this out) Is there a place on the forum where I can find what these measures mean and what range they should be in?

(links snipped)

Looks much better... the events are associated with waking... your min resp rate was 6.2, about normal. You still have leaking going on, but not too much for the machine to deal with. The second link just shows the bare O2 data, redundant with the first link. Your bi-level Ti parms probably need tuning, out of my league.

Here, read more:

TiControl - Inspiratory time control VAuto and S modes only Unique to ResMed bilevel devices, TiControl™ allows the clinician to set minimum and maximum limits on the time the device spends in IPAP. The minimum and maximum time limits are set at either side of the patient’s ideal spontaneous inspiratory time, providing a ’window of opportunity’ for the patient to spontaneously cycle to EPAP. The minimum time limit is set via the Ti Min parameter and the maximum time limit is set via the Ti Max parameter. TiControl’s Ti Max and Ti Min parameters play a significant role in maximising synchronisation by effectively intervening to limit or prolong the inspiratory time when required. This ensures synchronisation even in the presence of significant mouth and/or mask leak.

Do most people use SleepHQ or Oscar for tracking therapy?

I have never used SleepHQ for my own data. No need. I do use it when someone posts a link to it because I am looking for something specific.

I use OSCAR maybe once a month or so to review my data.

Mostly I just glance at the sleep report on the machine each morning when I turn the machine off.

But then I have been on 15 coming on 15 years in another month and I pretty much already know what my data looks like.
It hasn't really changed in years and years.

Nice! Now we can see some data. See those ramping up leaks starting at 2am? That's mouth leaking... are you taped? It's failing there... the rate is not over the 25lpm line but still not good.

See that crazy pulse rate spike around 12:30am? That's a ring artifact... some fitment problem, it got wiggled, etc. I had those go up to 200bpm until I found the good finger and taped it in place. I put it on my right middle finger first phalange, just like a clip-on pulseOx would fit... then I tape it in place with 1" of that CRST. I did cut all the elastic out of it to make it fit my ridiculously fat fingers. Is this an O2Ring?

Zero movement? Like a corpse! Not sure why your Movement shows zero unless a) your monitor doesn't support it or b) you really really are still.

See that desat zone around 01:40am? That's the only concern I see... your rates look good, arm asleep? 0 AHI is good!

Not at ring. The O2 is a Wellue Pulse Oximeter Fingertip Blood Oxygen Saturation Monitor from Amazon. I still have a fancy one but the recording software became absolute (however it let me check the accuracy against this inexpensive Wellue).
I tape it on the index finger (but now maybe I'll move it). A really annoyance but the O2 data provides a better measure of my quality of sleep than the CPAP. You can get three and a half nights out of a pair of AAA batteries.

sleephq is relatively new as compared with Oscar. more and more new folk are using sleephq. i'm given to understand that if you share a sleephq graph, other people can use it to zoom in on certain sections. that can be important in some cases. Oscar doesn't allow for that.

Drops in blood oxygen levels are called desaturations (see I'm learning). I'll watch how this trends in the coming weeks.
I have a question about "pressure." In the old days, I had a set pressure and if you asked me what my pressure was I could tell you. I don't know how to answer that question now. What is my pressure?

You're running an ASVauto with
maxEpap 15cm
maxIpap 30cm
minEpap 7cm
minIpap 10cm
psMax 15cm
psMin 3cm

It's complex! Click the 'more' link under Settings.

Read the respShop manual I linked above. OK, now I understand you have a different O2 monitor without movement. Actually thinking about buying the real deal Resmed module etc... 1000$... if they'd switch the medium finger for a large.
