My Sleep Study Results

[CpapedTexan]

Hi everyone,

Although I've been hanging around this forum for the past month, I am finally getting around to posting my sleep study results. This sleep study was preformed at UT Southwestern Hospital here in Dallas. The doctor said that my sleep apnea was mild, but what do you guys think based on this data??

Are those results from a diagnostic sleep study or from a titration or from a split-night study or other?

They are from a diagnostic sleep study. They did recommend a titration study which I had on Sept 9th. The doctor kept the results of the titration study, so I need to get another copy of those.

Well, I am no expert, but one of the experienced posters will definitely correct what I say if I am too far off. (They know I welcome that.)

Although your AHI (the average number of apnea and hypopnea events per hour ) is fairly normal, at 5, and your sleep architecture looks excellent (you must be young and fit), the number of arousals indicate that you might still get some benefit from PAP therapy, if you are having symptoms of excessive daytime sleepiness.

If your symptoms don't go away, you may want to ask your sleep doc about UARS and bilevel.

(There. If we're fortunate, that should stir up some responses from the more experienced posters. )

I think you nailed it, jnk.

Thanks for responding! The numbers from the titration study look a bit worse; I will post the results to those when I get a copy of the report Monday. I also have Pulmonary hypertension. I've been told that Cpap therapy could possibly reverse this.

The notation on my study report said that I should be warned that I will not feel the immediate effects of the Cpap therapy, but should improve with time. I'm hopeful.

DEFINITIONS:
APNEA = cessation of airflow for 10 seconds or greater.
HYPOPNEA =>50% decrease in airflow for 10 seconds or greater with a decrease in oxygen saturation of >3%.
APNEA/HYPOPNEA INDEX (AHI) = apnea plus (+) HYPOPNEA/hour of sleep.
RESPIRATORY AROUSAL INDEX (RAI) = AHI +snoring related EEG arousals/hour of sleep.
AHI/RAI** Scale =<5 events /hour = (none); 5-15 events/hour = (mild); 15-30 events/hour = (moderate); >30 events/hour = (severe).
Respiratory related sleep fragmentation: Sleep arousals due to respiratory events or snoring.
Desaturation = Drop in O2 oximetry distribution saturation by 3% below average saturation.
SaO2 scale: >89%=(none); 85-89%=(mild);80-84%=(moderate); <80% (severe).
EPWORTH SLEEPINESS SCALE =<10=(does not indicate EDS (Excessive Daytime Somnolence));10-15=(indicates daytime somnolence-not excessive);>16 (indicates EDS).
RESPIRATORY EFFORT RELATED AROUSALS (RERAs)=Sleep Arousals due to respiratory events characterized by pressure flow limitations in the airflow indicator channel without significant O2 desaturations.
StageIII and StageIV are combined and referred to as Deep Sleep.
Sleep Efficiency = Normal is >80%
As established by AASM/ABSM 1999.

Normal Sleep Architecture:
Stage1: 5%
Stage2: 50%
Stage3: 10%
Stage4: 10%
Stage REM: 25%

Stage3&4, REM decrease as we age.
