I hope someone out there can interpret these figures so I can begin understanding my diagnosis. Thanks in advance!

Study results:
Sleep Parameters:
Patient achieved 276 minutes of total sleep time. During diagnostic portion efficiency was 62%. During treatment 71%. No REM sleep
until after CPAP, with CPAP REM accounted for 40% of total sleep.

Respiratory Parameters:
Diagnostic phase, loud snoring. In first 104 minutes of testing, there were 2 obstructive apneas lasting 18-19 seconds. 252 obstructive
hypopneas with a max. duration of 41 seconds. Total Apnea/Hypopnea index (AHI) of 146.5 respiratory events per hour. Oxygen saturation
nadir was 78.4%
Treatment phase, CPAP was titrated from 4-13 cm H2O. At 10 cm H2O her AHI was 0.0 events per hour and SaO2 remained above 92%.

ECG revealed unifocal premature ventricular contractions 1 to 6 times per minute.

No REM sleep

That pretty much says it all.  An AHI of 30 events per hour is the threshold for severe OSA, and your AHI is very high.  The low oxygen level during the night is not a good thing and can take a toll on your organs and brain.  I hope you're adapting to CPAP because if those were my results I would be determined to make therapy work.  Good luck with your therapy.  I'm sure others will chime in.

Hi sleepytimebunny!

You have severe sleep apnea consisting mosty of episodes of reduced airflow (hypopneas).  Sleep efficiency is probably the effect of trying to sleep in the lab (time in bed verses time asleep normally arround 85%).  

I do not know what to make of the REM comments.  REM is normally 20% of sleep - you seem to have gone into "REM rebound" right away given the CPAP.  REM rebound occures since Sleep Apnea tends to steal REM time so there is often a time where the body catches up on all that dreaming it missed.

CPAP seems to do very well for you.  I hope you do well with it!

Sweet dreams!

The important data is that CPAP set at 10 cms of pressure totally elimimated ALL apneas AND hypopneas AND there were no other sleep disorders such as Periodic Limb Movements, central apneas, etc. SUCCESS! CONGRATULATIONS!

You might want to ask about the unifocal premature ventricular contractions 1 to 6 times per minute and their significance, IF ANY.
