I've had my 1st sleep study very recently and they don't give the AHI, but they do give the RHI but know how to compare it.
Quote:
The patient had respiratory disturbance index of 58.2 and had a large number of sleep apneas of 26 averaging 48.4/hour of sleep with a mean duration of 23.8 seconds, the longest being 36.7 seconds. The patient also has 41 of central apena averaging 7.5 per hour of sleep with a mean duration of 16.3 seconds and the longest duration of 24.7 seconds. Oxygen saturation was 85%. The patient's RDI got rather severe in the supine position at 92.5 and the patient spent 61.5 of sleep in the supine position.
Quote:
The patient had a large number of arousals averaging 57.6 per hour of sleep, majority of which are respiratory arousals that is 51.6 per hour of sleep.
Good news at least - average heart rate of 68 - an no arrhythmias documented.
The raw numbers scare me a bit, 41 central, 266 obstructive, and 11 mixed apena events over the sleep study.
I do know what obstructive apena is but still trying to learn about central apena and is 41 central apena (also had 11 mixed (central+obstructive) normal / what are some causes for central.
This is all new to me. I go for CPAP / sleep study tomorrow in fact. I'm very happy I've found this forum. How bad is this?
