I had a 2 night sleep study completed due to some night time waking with gasping and panic. I'm not sleepy during the day as much as I am what I would describe as fatigued. The Dr recommended CPAP, but seemed somewhat noncommittal on a diagnosis other than greater that 5 events an hour is good enough for the insurance company. What surprises me the most is the number of arousals which were not attributed to apneas and the reduction in those with CPAP. Does that have significance? I’ve read a bit about UARS and RERA (which were not measured here), but can’t really match that to this study. I was hoping the informed members of this forum would be able to offer some feedback, info or pointers. Study follows:

Total Recording Time: 425.0 min
Total Sleep Time: 209.0 min
Sleep Efficiency: 50.6% <~~~This is pretty low. It means you slept poorly, but you probably knew that!  
Sleep Onset: 11:47:50 PM
Sleep Latency: 99.0 min <~~~~This is how long it took you to fall asleep. This is way above average.
REM Latency: 65.5 min <~~~~This is how long it took you from sleep onset to go into REM sleep. This is lower than average, which can be a sign of chronic sleepiness, or even narcolepsy (But it's usually just sleepiness, narcolepsy's fairly rare)
Wake after Sleep Onset Time: 104.5 min<~~This is how long it was from sleep onset until you woke for the first time.;

Stage 1: 31.5 min (13.2%)
Stage 2: 159.5 min (76.3%) <~~~This is higher than normal because you didn't get any Delta (or deeper) sleep (Probably because of your hypopneas).
Stage 3: 0.0 min (0.0%)
Stage 4: 0.0 min (0.0%)
Delta: 0.0 min (0.0%)
REM: 22.0 min (10.5%) <~~~This is lower than usual. Normal REM percentage is 20-25%

Sleep Disordered Breathing: <~~Apnea means your breathing stops, hypopnea means your breathing is shallower than it should be
Obstructive Apnea Events: 0
Central Apnea Events: 0
Mixed Apneas: 0
Total: 0
Hypopnoea Events: 41
TOTAL: 41
AHI: 11.8 <~~~This is how many times your breathing was abnormal per hour of sleep. 10-15 times per minute is considered "moderate"
NREM AHI: 13.2 <~~~~This is how many times your breathing was abnormal per hour of REM sleep.
REM AHI: 0.0

Arousal Summary: <~~~this is a summary of how many times you either woke up or went to a lighter sleep each hour
Spontaneous Arousal Index: 38.76/hr <~~~This means your sleep was really restless, you had arousals or awakenings for no apparent reason 38.76 times per hour.
Apena+Hypopnea Arousal Index: 11.77/hr <~~~This is how many times per hour your arousal was caused by your breathing problems.
PLM Arousal Index: 0.86/hr <~~~This is how many times per hour your arousals were caused by leg movements
Total Arousal Index: 42.49/hr <~~~This is the total number of arousals per hour

No serious desaturation (lowest > 2 sec 93%) and only mild snoring. <~~This means your oxygen levels are good!

Titration: <~~~This is the information gathered while you were wearing the CPAP
Sleep Architecture:
Lights off: 10:17:57 PM
Lights On: 5:01:57 AM
Total Recording Time: 423.0 min
Total Sleep Time: 291.5 min
Sleep Efficiency: 72.2% <~~~~This means you slept better with the CPAP on.
Sleep Onset: 11:17:27 PM
Sleep Latency: 59.5 min
REM Latency: 89.5 min
Wake after Sleep Onset Time: 52.5 min

Stage 1: 14.0 min (4.8%)
Stage 2: 180 min (61.7%)
Stage 3: 49.5 min (17.0%)<~~This means you got a lot more deep sleep with your CPAP
Stage 4: 0.0 min (0.0%)
Delta: 49.5 min (16.98%) <~~This means you got a lot more deep sleep with your CPAP
REM: 48.0 min (16.5%)

Obstructive Apnea Events: 0
Central Apnea Events: 0
Mixed Apneas: 0
Total: 0
Hypopnoea Events: 5
TOTAL: 5
AHI: 1.0 <~~~This means your breathing is within normal limits with your CPAP
NREM AHI: 1.2
REM AHI: 0.0

Arousal Summary:
Spontaneous Arousal Index: 10.70/hr
Apena+Hypopnea Arousal Index: 1.03/hr
PLM Arousal Index: 0.00/hr
Total Arousal Index: 13.79/hr <~~~This means you wake much less often with your CPAP

No serious desaturation (lowest > 2 sec 92%) and snoring resolved at CPAP pressure 8.

All-in-all, I think you're going to feel a lot better once you get used to your CPAP and get caught up on all the sleep you've been missing!  

Good luck!

Thats a lot of numbers to look at, I just had mine done March 26th.  My numbers were quite high as well, and My titration study is Saturday when I get my first results I'll post them , looks like I'll need a bit of help cyphering the results

Thanks so much for the help Donna! Sounds like CPAP is the way to go. Like I said, the Sleep Dr was kind of noncommittal on a diagnosis  and a little wishy-washy with his recommendation. I happened to see my GP this week and she was very insistent I get CPAP after seeing the results. She kept looking at my chart, shaking her head and saying, "All this will get better after a good night sleep."

I'm still wondering if anyone else has such a high number of arousals which are not attributed to apneas or hypopnea which are  reduced with CPAP. Does that have significance? Or is it just a coincidence of the testing?

Thanks,
Dex

A lot of the arousals that are for no apparent reason could have just been from your being in a strange bed with a bunch of wires on you. Chances are you don't do this at home. Once you get used to your CPAP and feel you're sleeping well at night, if you're still tired during the day, let your sleep doc know and ask if he thinks you need to be retested to check on those spontaneous arousals.

Good luck!
Donna
