Just got the study results.
AHI 0
RDI 23.5
Titration portion was cut short as I woke up at 3 and couldn't get back to sleep on CPAP but showed RDI from 17.5 at 5cm for 45 minutes, 17.0 at 6 for 33 minutes, and 10.6 at 7 for 33 minutes.
Hadn't expected but perhaps a little hoped the "after" numbers would be better but I suppose in the worst case 80 disturbances a night is better than 180.
I didn't exaclty take to CPAP like a fish to water. First week at home I got at most 2 1/2 hours. On night eight I decided getting used to it was more important than getting anything out of it so I turned on the epr at 3 and made it a little longer. Last night I slept 3:40 then woke up, got up for 20 minutes to avoid feeling like I was fighting with it, then went back and slept another 3:40. Still quite tired on waking but I know at this stage I should expect to be. At least made it the whole night on the machine.
So far only one obstructive apnea logged by the machine (11 seconds) and a handful of centrals (11 to 24 with one 42). It seems to want to ramp up to the max but so far I haven't gotten used to more than 7 so I guess I'll leave it there with the epr on for a while and collect data while getting used to it.
Thanks to all for reading and for the feedback.
1041: Thanks for asking. Short form, tired but fine, with a shiny new 4-letter acronym
ps:
[from the report]
Findings:
Sleep/EEG: Awake, with eyes closed, the patient had a poorly formed alpha rhythm. [not sure what this means other than I was half awake]
Cardiac analysis: The EKG was sinus rythm with an average heart rate during the diagnostic portion of the study of 57.4, during the therapeutic portion it was 56.5, and no significant ectopy was observed.
Tibialis/EMG: Total limb movement indiex was 0
Interpretation:
EKG was unremarkable.
The patient has sleep disordered breathing in the form of snoring and respiratory effort-related arousals consistent with a diagnosis of upper airway resistance syndrome.
