Hi, I am another newbie and need some help interpreting my sleep study.  My report doesn't seem to have as much info as others, but here goes:

Patient is a 56 yr old female, 5'5, 170 lbs.  Meds: coumadin, Xanax

Excessive daytime sleepiness, snoring and witnessed apneas

SLEEP DATA

the patient was monitered for a total of 417.5 min., and slept for 310.5 min., resulting in a sleep efficiency of 74.4%.  Latency to sleep onset was 20.8 min.,REM latency from sleep onset was 194.0 min.

STAGE 1    7.4%   23.0 mins

STAGE 2     72.5%   225.0 mins

STAGE 3     6.6%   20.5 mins

STAGE 4      0.0%   0.0 mins

REM  13.5%  42.0 mins


Sleep effiency was decreased
sleep onset delayed
REM onset delayed
Patient slept in all positions

RESPIRATORY DATA

Total of 145 respiratory events were observed during the analysis period as follows, 84 obstructive apneas, 4 central, 0 mixed, and 57 hypopneas: for a apnea/hypopnea index of 28.0, and 21.4 during REM.  The respiratory events were repetitive and were associated with oxygen desaturation and marked disruption of sleep.  The lowest oxygewn saturation recorded was 80.0. Respiratory events increased in supine position.  Pulse oximeter readings may be misleading at times.  Patient took xanax before study ( I didn't take it at all)

Snoring
Light to moderate

Cardiac data

variant heart and occasional PACs (???)

AROUSAL STATS

a total of 249 arousals were observed during the analysis period as follows: 115 respiratory arousals, 32 PLM arousals, 20 spontaneous arousals, and 82 RERA/UAR arousals with a REA index of 38.1

PLM STATS

a total of 62 limb movements in PLM sequence were observed, the longest being 4 seconds.  Total of 9 PLM sequences were observed , the longest being 342 secs>  (???)

Impressions

OBS as noted by an AHI of 28, treatment recommended

Thanks for your time,

Hi honda:
Gotta run right now (literally) but in the meanwhile, read Linda's Guide to Sleep Studies to get the basic stuff out of the way.

Hi sleepydave

Did my reading, Lindas' guide was very informative, thanks.  The cardiac stats,PLM sequences, are very vague, can you explain those?  

I have an appointment at the sleep center, a week from today, and would appreciate your imput on the previous study,(above) and any suggestions for the equipment and CPAP.It has been years,at least 7, since I felt as though I had a good nights sleep and woke up feeling refreshed.  

I am looking forward to the  CPAP, and hoping it will have a very positive effect on my over all health...

Hi honda:
Occasional Premature Atrial Contractions (PACs) are generally no big deal.  I don't know what "variant" refers to.

That's a low number of Periodic Limb Movements, if you're gonna have them (and they're quite common, occur in about 10% of patients) you usually have a couple hundred.  Wait till after the CPAP titration, and if they disappear, they weren't really PLMs, probably just some movement related to perhaps respiratory events; or, as sleep continuity is achieved with CPAP, they may come to fruition and you'll end up with bunches of the things.  Regardless, they're harmless unless they generate an arousal.

Wait till the titration till you decide on a machine, it may turn out that you'll need some feature that appears on one, or works better, than another, like expiratory relief.

Hi sleepydave,

Thanks for the comments, one other question though, do  the 4 central apneas have any significance ?

None whatsoever.
