Severe obstructive sleep apnia during baseline.(Titration of cpap showed improvement with the best pressure at 17cwp)only minimal supine sleep was obtained during the night.
Severe periodic limb movements of sleep with an index of 50.6. The overall periodic limb movements of sleep are likely higher and that it was underscored due to frequency of the obstructive events during baseline.
128 apneas and hypopneas
02 saturation of 83%
RERAs 75
RDI     77
Is there any other number from the report to be able to help me see the level of severity of the sleep disorder.

Normal sleep is defined w/an AHI under 5; mild sleep apnea is an AHI 0f 5 -15, moderate sleep apnea is an AHI of 15-30 and an AHI of more than 30 is classified as severe.

AHI = the number of apneas and hypopneas PER HOUR OF SLEEP.

Most people experience a higher number of apneas/hypopneas per hour during REM sleep and whilst supine (sleeping on their back). RERAs are Respiratory Effort Related Arousals. The PLM index of 50.6 indicates that many limb movements per hour. PLMs can disturb sleep and cause arousals from sleep as well. They CAN be caused by OSA or be due to other causes. Your RDI (respiratory disturbance index) is 77, MORE THAN ONE PER MINUTE during your sleep!

Your 02 saturation should NEVER go below 90% for ANY length of time when you are at rest. Of more importance than how low your desaturations went is HOW LONG it remained at that level and HOW OFTEN.

You might say "you've got it bad and that ain't good" to coin an old phrase.

Hi awakehate,

You might look to see how different is AHI compared to RDI (if your report includes AHI).
They're both likely severe, but I'm guessing your RDI is higher than your AHI due to your RERAs.  
But it's a moot point because mild, moderate and severe sleep apnea is still sleep apnea and needs to be treated.
Some reports identify several AHI numbers.  There's an overall AHI (or RDI); there's an AHI during only REM, and an AHI during non-REM.  
As to the oxygen saturation number is not clear.  It could be an overall average for your sleep time.  Or it could be the nadir, or lowest recorded saturation.  Knowing both gives you a better idea of how bad are your oxygen levels.

So when are you getting your cpap?
