Recording accelerometer, my second "hardware" game changer
#11
RE: Recording accelerometer, my second "hardware" game changer
Thanks so much

I have a scheduled follow up to my sleep study. It's in 3 weeks. Tech told me I'll get two prescriptions. Mask. Pressure. I have restless leg. Diagnosed 25+ years ago during my first study.

I've had my best scores since I stopped EPR

Highlight for me is that help here has satisfied my worry that I could do better with cpap treatment. I'm doing really well.

I started a thread here talking about sleep quality. My sleep doctors have never addressed this.

A contact at my DME was taken aback by my comment to her. I said if I'm wearing this gear, it better work. I don't tolerate 5 as an acceptable score. I search for answers and get my numbers down. She said 5 or less was compliant. I said compliant isn't good enough

Recently I had two nights with 0.0, back to back. P=11. No EPR. Nasal mask and pad under my chin to keep my jaw closed. Over 8 hours sleep each night.

I take Rescue Remedy regularly before sleep. It helps. Holistic. Stress.

I'm just a cpap user like you. I don't give medical advice. Seek the advice of a physician before seeking treatment for medical conditions including sleep apnea. Sleep-well

RE: Recording accelerometer, my second "hardware" game changer
The RT at my DME - FPM Solutions - tells me that masks are not a prescription item in Canada, so I'm not sure why yours thinks you need a mask prescription. Advice, sure, always welcome. Unless they are tracking your sleep a lot more rigorously than my sleep doc ever did, they just don't know how your mask and machine are working.

RE: Recording accelerometer, my second "hardware" game changer
A PM told me that it would be helpful to explain the sleep position chart in my OP. 


I asked my wife how she would explain the red and blue traces on my chart and, no nerd, she said rolling to left or right side from supine position or passing through the supine position is a rotational motion (as is indicated by the red horizontal graph line). The other motions, she indicated, show mainly some small up and down motions (much smaller, but a bit like doing sit up exercises, rising from supine to sit squarely on the butt and then lying back down, no side to side rotation). That lying down position (supine or on the side) and the neck tilting motions, up and down, are indicated by the blue horizontal graph line. If troubling, simply ignore the blue trace. I present it because it tends to confirm moves in the red graph and in some cases it shows a larger move.


I added some notes to last night's graphic, below, which I hope will convey the idea.

Other comments/questions about the "false negative" (0.0 AHI) Flow Rate in the graph below.
Given the need to post a better explanation I'll "flog this old horse" some more with comments and questions centered mostly on last night's Flow Rate wave form variations.

1. Preventing myself from sleeping on my back (as I have with a chock in my sleep vest's "backpack" pocket) did not stop or reduce my snoring last night; it flared just to the right of the vertical ruler and continued until I got up for a pee break. I don't know if it caused the concurrent LLs. I had been seeing very little snore if rotated farther than 15 degrees away from supine to left or right.

2. A Flow limit spike (see it by the ruler) had triggered a pressure rise to about 11.09 cm just before snores hit hard; the A10 quickly upped the pressure enough to keep passages from closing and kept enough pressure to carry me to the break. Lacking that timely boost of pressure my bet is there would have been a string of OAs up to the break. (Hence "false negative". I have flow resistances that large that do not trigger a pressure increase.)

3. The Flow Rate curve shows about 3 slow downs or attenuations at 3 narrow "wasp waists" located to the right of the ruler and before the break. Coinciding with those three are LL peaks at about 7:17, 7:45 and 8:17. I ask if the leaks dropped the pressure causing reported breathing volume and flow rate to
fall as shown in Tidal Volume and Flow Rate graphs. The mask pressure graph is steady--maybe indicating that it is based on projecting from some algorithm, given that there is no in-the-mask transducer.

4. Again, the many flow rate spikes and their association with movements in the graph do suggest that sleep could be much more restful if those were reduced. It's clear that most all the motions indicated along the  red and blue traces are coincident with many but not all larger positive spikes. The number of large Flow Rate spikes (not counted tonight) probably is more than the magic " you are treated" criterion of  five or fewer per hour.

I would appreciate any suggestions. Lacking any responses, it's time for this old nag of a horse to have breathed its last.

I have no particular qualifications or expertise with respect to the apnea/cpap/sleep related content of my posts beyond my own user experiences and what I've learned from others on this site. Each of us bears the burden of evaluating the validity and applicability of what we read here before acting on it.  

Of my 3 once-needed, helpful, and adjunctive devices I have listed, only the accelerometer remains operative (but now idle). My second CMS50I died, too, of old age and the so-so Dreem 2 needs head-positioning band repair--if, indeed, Dreem even supports use of it now.
