Sleep apnea

Well the reason they wanted me to come in to discuss my results of the sleep study honestly really suprised me! I didnt move my limbs so no RLS like I thought but I was diagnosed with obstructed sleep apnea. Crazy.. I was suprised because I don't snore.. at all. Ever.
but was diagnosed with sleep apnea and start CPAP here this week.
Here is my report:

FINDINGS:

(skip to number 2.. the good stuff)

2. Sleep architecture: Sleep latency was 37.7 minutes, which is slightly increased. The patient slept for 279.3 minutes out of a recording time of 509.9 minutes, acheiving a sleep efficiency of 54.8% The patient spent 18.8% of the night in N1 sleep, 50.1% of the night in N2 sleep, 20.8% in N3, 10.3% in REM sleep. The REM latency was 364.5 minutes which is markedly increased. The patient had 239 arousals for an arousal index of 51.4, which is consistant with severe sleep framentation. 3. Cardiac: The patients initial heart rate was 90 and heart rate at the end of study was 81.
initial blood pressure 117/75. Cardiac rhythm was normal sinus rhythm througout.

4. MOTOR: The patient spent 40.3% supine and 59.7% on her right side. The patient had no
limb movements. The patient had 4 respiratory event related arousals for a respirartory
event related arousal index of 0.9.

5.RESPIRATORY: During the total of 279.3 minutes of sleep, this patient displayed no apneas
and 162 hypopneas, for an apnea hypopnea index of 34.8 and combined respiratory disturbance
index of 35.7. The patient did not demonstrate significant desaturation during the course of
the night.

6. CONCLUSION: Abnormal sleep architecture to include mildly increased sleep latency, increased
N1 sleep, decreased N2 sleep, and delayed REM latency. This is likely a combination of first
night effect as as for obstructive sleep apnea. There were no significant cardiac or motor
disturbances seen. The patient did demonstrate severe obstructive sleep apnea with an
hypopnea index of 34.8 without oxyhemoglobin desaturation.

Reccomendations: In light of the patients symptoms and the results of the polysomnogram, she
does meet criteria for a diagnosis of obstructive sleep apnea syndrome. She would likely
benefit from a CPAP titration. Weight loss is unlikely to have a significant benefit for this
patient as she allready has a BMI of only 19.9. If CPAP is not thought to be acceptable or
tolerated, other treatment options are oral surgery such as mandibular advancement or an
oral appliance, although these would not be felt to be as efficacious as CPAP in most
circumstances.

AXIS A: obstructive sleep apnea 780.53-0
AXIS B: Polysomnogram 89.17
