RE: Help Needed with SleepyHead on Mac
Kate 1898 and DeepBreathing,
I'm finally getting to your suggestions and comments. Thanks for your patience.
Kate - I downloaded AppCleaner, removed my old SH, and downloaded the broken GL version. Still no luck. I'm running OX 10.8.5--not the newest OS but not too old either, so I doubt age is the issue. In case it's relevant, while trying to import data, I got a message which I've attached as "Grab 1." I responded to that by (properly or not) deleting the folder from my documents folder. In any case, there was no data to be seen.
DeepBreathing - As noted, no data this time, either. I've attached a screenshot as Grab 2 showing what I'm getting (or not getting). I welcome other ideas.
As for my medical condition, thanks for your "blunt" comments. I am in the process of arranging to see a new cardiologist. Between 2009 and 2012, I did three echos, all showing my ejection fraction (EF) at the lower limit of normal (LLN), which the cardiologists kept reading as perfectly fine. I did these echos in response to an increase in my respiratory rate when I'd lie down in bed--I guess you'd call this recumbent relative tachypnea--but with no dyspnea. However, during the past year, I've developed dyspnea on reclining (i.e., orthopnea), which as gotten worse over the past several months. I'm in the process of trying to connect with a different (academic) cardiologist who is an expert in global strain echocardiography, which is said to be more sensitive and precise than traditional EF measurements, because I don't want to end up with another LLN read as normal and telling me to go home. The strain analysis should give a more sensitive test if there is something serious going on, even if my EF is in the normal range. I've just sent this new (prospective) cardiologist's office my most recent polysomnogram; once I see him, if he feels there is in fact a cardiac problem, I'll definitely connect him and my sleep doctor.
As for my sleep study: I just started seeing a new doctor, an expert in complex sleep apnea, and had a PSG last week (this was my 11th or 12th since 2000) which showed an AHI in the low 20's, consisting almost entirely of hypopneas, including both obstructive hypopeas during REM and central periodic-form hypopneas during Non-REM. These NREM hypopneas apparently involve periodic respirations with the hypopneas at the troughs, but there is some element of (partial) respiratory effort present as well, so they are being scored automatically as obstructive, though the doctors are calling them primarily centrally mediated, based on the incomplete respiratory effort and their periodic form. My desats are not too bad, a low of 84% and only 2 minutes spent below 87% during four hours of sleep. However, my sleep is badly fragmented, with 0 time in N3 and only 13 minutes in REM.
The doctors are describing my situation as "severe complex/mixed" with evidence of both REM-dominant obstructive disease and NREM-dominant centrally mediated disease. They are pescribing an extensive sent of interventions, some of which I've already been doing. The complete new regimen being recommended is: (1) auto-CPAP 8-12 range (I've currently been using fixed CPAP at low pressures, like 6 cm) to deal with the REM obstructive hypopneas without, hopefully, exacerbating the central hypopneas; (2) continued use of my mandibular advancement device and (3) "back pack" to keep me off my back--again for the obstructive component; to which they are adding (4) 100 cm of dead space to raise inspired PCO2 and (5) acetazolamide--both for the central component. On my own, I'm in the process of buying a recliner to see if sleeping semi-upright has any benefit (and it's likely to be helpful for when I have orthopnea in any case). Oh, by the way, I sleep with tape over my mouth for a bad mouth leak with my nasal mask (so far, I've not found a FFM that first well enough) and I recently started sleeping also with a foam cervical collar to prevent "neck tuck." I'm not a very appealing bed partner, as you can imagine.
If you have any comments, they're most welcome; you sound like someone with a good bit of knowledge and experience...
Thanks to all.
