First of all, thanks to all the great people here.  This site has been a real blessing in a trying time.

I just got my sleep study results.  It was a split study.  Please help me to deciper.

Standard Summary
Total Sleep Time: 214 minutes
Sleep Efficiency: 70.6%
Sleep Latency: 10.3 minutes

REM Sleep: 3%
REM Latency: 169.0 minutes

Stage 1: 27.3%
Stage 2: 48.4%
Stage 3 & 4: 15.5%

** Patient was noted to have loud snoring during the study.

Central Apneas: 6
Obstructive Apneas: 168
Mixed Apneas: 61

Apnea Index: 65.9

Hypopneas: 44
Apnea-Hypopnea Index: 78.2

Supine Position: 27.7%
Supine AHI: 28.6
Non-Supine AHI: 86.8

REM AHI: 6.2
Non-REM AHI: 79.2

Lowest Saturation: 49.0%
O2 Saturation less than 90%: 29.7 minutes


CPAP Summary
Total Sleep Time: 134.5 minutes
Sleep Efficiency: 52.5%
Sleep Latency: 10.3 minutes

REM Sleep: 45.4%
REM Latency: 406.5 minutes

Stage 1: 16.7%
Stage 2: 26.4%
Stage 3 & 4:   6.1%

Central Apneas: 6
Obstructive Apneas: 0
Mixed Apneas: 0

Apnea Index: 2.7

Hypopneas: 27
Apnea-Hypopneas Index: 14.7

Supine Position: 24.7%
Supine AHI: 0.0
Non-Supine AHI: 15.6

REM AHI: 19.7
Non-REM AHI: 10.6

Lowest Saturation: 78.0%
O2 Saturation less than 90%: 6.9 minutes

CPAP Titration: Nasal CPAP was initiated at 4cmH20.  Pressure was slowly titrated to a pressure of 15cmH20 with an index of 17/hr remaining.

Impression: Obstructive Sleep Apnea, severe with severe O2 desaturations.

Recommendations:  
+Consider full night CPAP titration
+Consider Autotitrating Nasal CPAP to gain more information regarding pressure requirements
+Weight reduction might be helpful (Grade 2 obesity, 6'1'' 235lbs)
+Refrain from Driving Vehicle until daytime sleepiness eliminated
+Follow patient closely to assess efficacy of therapy

I have an appointment with the Medical Director that analyzed my Sleep Study next week.  In the meantime, they are setting me up with an APAP.

Any insights would be greatly appreciated!!!

Thanks,

Hi RS:
And I see from your other post you got the APAP.

With 2 "severe" in the same line, that pretty much tells it all.

In your list of things that were slow to materialize, you might ask how come with a severe RDI, severe desats, and a short time frame to work with in the split study format, they "slowly" titrated.  Shoot, crank that thing up.

But getting on the APAP this quickly is the right thing to do.  You could get the CPAP Titration table from the study, and the download results from the APAP.  I'd be looking to get that low limit of the APAP up, if they set it at the minimum, but that might be OK for a few days.  Also, you have to make sure that all your desats are covered by your final pressure.  The CPAP Titration table will give us a clue as to whether or not you need another PSG or at least a nocturnal oximetry (could be done at home).
