Diagnostic Polysomnogram
Patient Name: / Snorty McSleeperson / Study Date: / 12/9/2013
Dear.: / Dr. Smarty Pants
Objective Report Data
SLEEP DATA:
The patient Snorty McSleeperson underwent an overnight polysomnogram on 12/9/2013. Sleep efficiency was 98.3%. Sleep architecture included 385.8 minutes total sleep time, 24.0 minutes N3 sleep, and 81.3 minutes of REM sleep. The initial sleep latency time was 0.0 minutes.
RESPIRATORY DATA:
During the study the patient had a total of 296 obstructive apneas, 0 central apneas, and 36 obstructive hypopneas. This gives an average apnea-hypopnea index of 51.9 per hour (normal is < 5 per hour) with a Supine Index of 70.2. The AHI is the sum of all apneas and hypopneas divided by the total amount of sleep time. No snoring was noted during the study.
LEG MOVEMENT DATA:
There were 0 Periodic Leg Movements with an index of 0.0 per hour.
ECG DATA:
The average pulse rate during sleep was 92 bpm.
OXYGEN SATURATION DATA:
The patient’s SaO2 at the start of the study was 97%. The average oxygen saturation in Non-REM was 92% and REM was 89% and the lowest oxygen saturation was 73%.
Physician Interpretation:
Impressions:
  1. Obstructive Sleep Apnea Syndrome.
  2. Periodic Limb Movements of Sleep, Asymptomatic.

Recommendations:
  1. The patient should return for a complete-night titration to determine the potential effectiveness of this treatment modality.
  2. The patient follow-up with a sleep dentist to get fitted for an oral corrective device, or an otolaryngologist for possible surgery, to treat snoring if clinically indicated.
  3. The patient should return for a consultation with a sleep specialist to correlate the patient’s history with the clinical findings.
  4. Treatment of PLMD with a dopaminergic agent, such as Pramipexole or Ropinirole, if the patient has symptoms of restless legs syndrome.
  5. The patient should be cautioned about factors that may potentially exacerbate snoring and sleep-related problems, such as CNS depressants, especially at bedtime.
  6. The patient should also be cautioned about driving and operating dangerous machinery until the condition is treated and the daytime symptomatology is eliminated.
  7. Weight loss for the ideal body weight range is recommended.
Clinical Code:
  1. Obstructive Sleep Apnea (327.23).
  2. Periodic Limb Movement Disorder.
I certify that I have reviewed the raw data in accordance with the AASM guidelines for accreditation.
Thank you for asking AXG Sleep Diagnostics to evaluate this patient. Please feel free to discuss the results of the study with me at any time.

Sincerely,

Procedure:
Polysomnography was conducted on the night of 12/9/2013. The following were monitored: central and occipital EEG, electrooculogram (EOG), submentalis EMG, nasal and oral airflow, thoracic wall motion, anterior tibialis EMG, and electrocardiogram. Arterial oxygen saturation was monitored with a pulse oximeter. The tracing was scored using 30 second epochs. Sleep latency was defined as lights out to the first epoch of any sleep (AASM). Hypopneas were scored per AASM definition VII.4.A (4% desaturation). / Sleep Staging Data: /
