And it’s not as bad as it sounds. I suffer from sleep apnea, and I have an CPAP machine which records all sorts of data. Including Central Sleep Apnea.
Anyhow, onto the web links:
SecondWindCPAP (I purchased a Resmed S9 APAP machine, which I’m very happy with)
SleepyHead – software which allows you to read sleep data from some machines.
