cpap Rassessment Polysomnography Assessment help

Post by countman88 » Mon May 26, 2008 9:07 pm

Have just rec'd a copy of my study and would like feedback as to how it looks. Excerpts as follows:
Procedure: A full psmg was performed measuring EEG,EOG,EMG,ECG, snoring, oximetry, cpap pressure and airflow, abdominal and thoracic effort, and limb movements.
Leg Movements: Nil abnormal leg movements
Average Heart Rate: 54bpm
Architecture: There were adequate periods of REM and NREM sleep for analysis. Several prolonged periods of consolidated sleep. Total time spent awake after sleep on-set was 34 mins. (I should add here that quite a bit of the time awake was caused by them adjusting equipment etc.)
Sleep Stats: Total Sleep Time 408 mins, sleep latency 16mins, Efficiency 89.1%, REM latency 78 min, MREM sleep 326 min (80%), Supine Sleep 211 mins (58%, REM Sleep 82 mins (20%), Lateral Sleep 197 mins(48%), Awakenings: 20
Stage 1, 6min, 2, 232 mins, 3, 9 mins, 4, 78 mins, REM 82 mins.
Arousal Index #per hour, total 7.1, NREM 4.2, REM 18.3.
SpO2% stats.: NREM REM
Baseline% 95 95
Mean % 94 94
This data reflects the entire duration of the study and therefore includes respiratory events and arousals that occurred at sub optimal cpap pressures

Cpap Titration- cpap was well tolerated and Mr D. achieved a sleep efficiency of 89%. Cpap of 9cmH20 proved sufficient to eliminate snoring and almost all obstructive respiratory events and maintain a satisfactory SpO2%.
Suggested management: Reduce to 9cmH20 CPAP

I don't understand a great deal of this and would appreciate some views on how I appear to be going.

In one of you recent posts you mentioned that you've been a satisfied user of a cpap for 6 years, and a pressure of 12.

Look like the PSG agrees you do well - but thinks you can do with less.

Good, means NO PLM or RLS syndromes.

Average Heart Rate: 54bpm

Looks good to me, no racing heart

Architecture: There were adequate periods of REM and NREM sleep for analysis. Several prolonged periods of consolidated sleep. Total time spent awake after sleep on-set was 34 mins. (I should add here that quite a bit of the time awake was caused by them adjusting equipment etc.)
Sleep Stats: Total Sleep Time 408 mins, sleep latency 16mins, Efficiency 89.1%, REM latency 78 min, MREM sleep 326 min (80%),

Sleep positions tested:
Supine Sleep 211 mins (58%, REM Sleep 82 mins (20%), Lateral Sleep 197 mins(48%), Awakenings: 20
Stage 1, 6min,
Stage 2, 232 mins,
Stage 3, 9 mins,
Stage 4, 78 mins,
REM 82 mins.

above looks like normal sleep architecture to me (means there wasn't many arousals to destroy it).

Arousal Index #per hour, total 7.1, NREM 4.2, REM 18.3.

A little high for me but not bad.

SpO2% stats.: NREM REM
Baseline% 95 95
Mean % 94 94

Baseline is your awake sample SAO2 rate, Mean is your avg. during sleep so you only dropped by 1% which is good.

This data reflects the entire duration of the study and therefore includes respiratory events and arousals that occurred at sub optimal cpap pressures

Cpap Titration- cpap was well tolerated and Mr D. achieved a sleep efficiency of 89%. Cpap of 9cmH20 proved sufficient to eliminate snoring and almost all obstructive respiratory events and maintain a satisfactory SpO2%.

Try to find out if the recommended pressure took into acoung your REM sleep.

hi,

your sleep architecture seem fine and normal. but where is the ahi score?

**tips: sleep on your and your pressure will drop event more due to reductions of gravity pull to clsoe up your airway.

snoredog is right.

Thanks everyone for your comments. Snoredog, is the "Arousal Index # per hour" another term for AHI?
Bit confused by Total 7.1. NREM 4.2, REM 18.3
When you say many of the categories are normal, do you mean that I am achieving similar sleep to someone without sleep apnea?
Also, Guest?, you appear to have missed out a critical word with your suggestion to sleep on your ???. Is this side? I am surprised the study indicated I spent 211 mins on my back and 197 on my side, as when I go to sleep I am always on my side, and when I wake, nearly always on my side. Presumed I slept almost completely on my side. May have to resort to the golf ball sown into a pocket on my back.
