Recording time = 389 minutes
Total sleep 346
Sleep efficiency 89.1%
Stage Awake =10.9%
Stage I = 10.4%
Stage II = 85.7%
Stage III and IV = 0%
REM = 3.9%
Sleep Latency = 7 min.
REM Latency = 357 min

1 obstructive apnea, 281 hypopneas
apnea/hypopnea index = 48.8 events per hour

AHI REM 57.8 events per hour
Longest respiratory 20.5 seconds

Low saturation = 83%

Can someone tell me what this meas in laymans term and how severe is my apnea.
Thanks

Hi Zeek!
To classify the severity of OSA, I kinda like this format:

Quote:

Mild:  An apnea-hypopnea index from 5 to 14.  An oxygen saturation of at least 86%.  Unwanted sleepiness or involuntary sleep episodes occur during activities that require little attention.  Examples include sleepiness that is likely to occur while watching television, reading, or traveling as a passenger.  Symptoms produce only minor impairment of social or occupational function.
Moderate:  An index from 15 to 30.  An oxygen saturation of 80% to 85%.  Unwanted sleepiness or involuntary sleep episodes occur during activities that require some attention.  Examples include uncontrollable sleepiness that is likely to occur while attending activities such as concerts, meetings or presentations.  Symptoms produce moderate impairment of social or occupational function.
Severe:  An index greater than 30.  An oxygen saturation of 79% or less.  Unwanted sleepiness or involuntary sleep episodes occur during activities that require more active attention.  Examples include uncontrollable sleepiness while eating, during conversation, walking, or driving.  Symptoms produce marked impairment in social or occupational function.

AHI and EDS references from:
Flemons WW. Sleep-related breathing disorders in adults: recommendations for syndrome definition and measurement techniques in clinical research. Sleep 1999;22(5):667-89.

So, figure in your level of sleepiness, but you're pretty severe.  In the CPAP study which I'm SURE you're heading out for, look for some increases in REM sleep (barring any medications that might upset that) and hopefully a little boost in the Stage 3/4.

As well as getting rid of all those pesky respiratory events.
