My sleep study was done in July, it was a split-study. Here are the results...

Results without CPAP:
The first portion of the study was done without CPAP and lasted a total of 248 minutes,
sleep latency 3 minutes
REM latency 234 minutes
sleep efficiency 91%
total sleep time: 225 minutes

sleep distribution: 6% stage 1; 81% stage 2; 10% stage 3; 3% stage REM

Snoring was mild. There were a total of 66 scorable events, primarily hypopneic and 55 respiratory related arousals. The respiratory disturbance index was 32, supine 59. Oxygen saturation was well maintained. The arousal index was 37 with reactive cyclic tachycardia/bradycardia

Results with CPAP:
applied a total of: 155 minutes
sleep latency: 22 minutes
REM latency: 79 minutes
sleep efficiency: 85%
total sleep time: 131 minutes

sleep distribution: 12% stage 1; 50% stage 2; 20% stage 3; 18% stage REM

CPAP was titrated to as high as 6 cm which was maintained for 7 mins. 5 cm was maintained for 88 minutes, associated with a respiratory disturbance index of 10, and arousal inidex of 12 and included supine REM.

The overall arousal index was 15. PLM activity was reduced from 28 to 14. Reactive cyclic tachycardia/bradycardia seemed to be reduced. Review of the sleep hypnogram shows improved REM progression and sleep consolidation under pressure.

Lab Impression:
1. Severe positional sleep apnea documented the first portion of the study evidenced by mild snoring, a respiratory disturbance index of 32, supine 59 with sleep fragmentation, reactive cyclic tachycardia/bradycardia.
2. Near successful CPAP titration
3. Insufficient sleep syndrome with the patient averaging 5 to 6 hours of sleep per night

Recommendations:
This patient appears to have an insufficient sleep syndrome and underlying anxiety based mood disorder. She will be counseled about an appropriate sleep period of 7 to 8 hours. Further evaluation and pharmacotherapy forh er underlying anxiety may also be of benefit.

My questions:
1. Could someone explain my Sleep Distribution?

2. What the heck is reative cyclic tachycardia/bradycardia? I remember my doc saying that if I had not been dx with osa, that he thought in the future I would probably have a heart attack/stroke. He said that my heart would increase during an episode. But still not sure if I understand this or not.

3. What is pharmacotherapy? and is insufficient sleep syndrome the same as OSA?

Thanks for your help.

Now AHI=2.3 woohoo

Bradycardia = slow heartbeat characterized by a pulse rate below 60 beats per minute
Cyclic = periodic, occurring in cycles
Insufficient sleep syndrome = you are getting insufficient sleep. And quite likely insufficient bed time. You MUST allow for enough bed and sleep time. You need to go to bed at an hour that allows for at least 8 hours sleep before the time you MUST get up.
Pharmacotherapy = the use of medicine in the treatment of disease
Reactive = responding to stimulus
Tachycardia = abnormal rapidity of heart action; usually defined as a heart rate greater than 100 beats per minute in adults
