Sleep Study Transcribed Sample Reports For Medical Transcriptionists

Sleep Study Transcribed Sample Report #1

DATE OF TEST / DATE OF STUDY: MM/DD/YYYY

REASON FOR THE TEST: Extreme daytime fatigue, somnolence and obstructive sleep apnea.

Sleep parameters showed total recording time of 414.5 minutes and total sleep time of 333 minutes with sleep efficiency of 82%. Latency to sleep onset was 10.5 minutes and latency to REM sleep was 116.5 minutes. Number of awakenings were 6 and awake after sleep onset was 55.5 minutes. Sleep parameters showed awake time of 66 minutes or 15.9% of total. Stage I was 172 minutes or 51.7% of total. Stage II was 144 minutes or 43.2% of total. Stage III and IV was 3.5 minutes or 1.1% of total. REM stage was 13 minutes or 3.9% of total. Cardiopulmonary parameters showed heart rate was 90 during awake and 91 during sleep time. Respiratory rate was 16 during awake time and 14 during sleep time. Periodic leg movements were 103 with no arousals and the index was 18.6 per hour. Respiratory data showed total number of apneas and hypopneas was 47 with 4 apneas and 43 hypopneas. Apnea index was 0.7 per hour and apnea/hypopnea index was 8.5 per hour. Arousal index was 1.8 per hour. The total number of REM events was 7. Desaturation profile showed 3 events with O2 saturation between 60-65%, 7 events with O2 saturation between 65-70%, 10 events with O2 saturation between 70-75%, 11 events with O2 saturation between 75-80%, 17 events with O2 saturation between 80-85%, 17 other events with O2 saturation between 85-90%, and 54 events with O2 saturation between 90-95%. The longest respiratory event was 38 seconds and the lowest desaturation was 60%. Snoring was recorded to be 3-4/10. Epworth sleepiness scale was 19/24.

IMPRESSION: This test shows:
1. Poor sleep efficiency, probably secondary to first-night effect.
2. Disturbed sleep architecture.
3. Mild obstructive sleep apnea.
4. Severe desaturation during the night.
5. Severe daytime somnolence as reported by the patient.

Sleep Study Transcribed Sample Report #2

DATE OF TEST:

REASON FOR TEST: Daytime somnolence, excessive sleepiness during the daytime and fatigue.

The total recording time was 479.3 minutes and total sleep time was 426 minutes. Sleep efficiency was 91%. Latency to sleep onset was 1.5 minutes. Latency to REM sleep was 104 minutes. Number of awakenings were 14. Awake after sleep onset was 41. Sleep percentages showed awake time was 42.5 minutes or 8.9% of total. Stage I was 97.5 minutes of total or 22.9% of total. Stage II was 206 minutes or 48.4% of total. Stage III and IV were 61 minutes or 14.3% of total. Cardiopulmonary parameters showed a heart rate of 55 during awake and 50 during sleep and a respiratory rate of 16 during awake and 12 during sleep. Periodic leg movements were 23 with no arousals and the PLMS index was 3.2 per hour. Arousal index was 0 per hour. Respiratory data showed total number of apneas and hypopneas of 9, number of apneas 3 and number of hypopneas 6. Apnea index was 0.4 per hour and apnea-hypopnea index was 7.3 per hour. Arousal index was 0.7 per hour. There were no REM events. Desaturation profile showed 3 events with O2 saturation between 50-55%, 3 events with O2 saturation between 55-60%, 2 events with O2 saturation between 60-65%, 3 events with O2 saturation between 65-70%, 3 events with O2 saturation between 70-75%, 1 event with O2 saturation between 75-80%, 5 events with O2 saturation between 80-85%, 15 events with O2 saturation between 85-90%, 41 events with O2 saturation between 90-95%, and 1 event with O2 saturation above 95%. The longest respiratory event was 21.3 seconds and the lowest desaturation was 24%. There was one event with O2 saturation between 30-35% and one event with O2 saturation less than 30%. There was no snoring during the night. The patient’s Epworth sleeping scale is reported to be 4/24.

IMPRESSION: This test shows:
1. Normal sleep architecture.
2. No obstructive or central sleep apnea.
3. Severe desaturation during the night, which explains the patient’s fatigue during the morning.

Sleep Study Transcribed Sample Report #3

DATE OF TEST:

REASON FOR TEST: Excessive daytime fatigue and sleepiness.

Total recording time was 450.8 minutes. Total sleep time was 256 minutes. Sleep efficiency was 58%. Latency to sleep onset was 90.5 minutes and latency to REM sleep was 252.5 minutes. Number of awakenings were 7 and awake after sleep onset was 94.5. Sleep percentages showed awake time 184.5 minutes or 40.9% of total. Stage I was 70 minutes or 27.3% of total. Stage II was 64 minutes or 25% of total. Stage III and IV were 95 minutes or 37.1% of total. REM stage was 26.5 minutes or 10.4% of total. Cardiorespiratory parameters showed heart rate of 73 during awake and 74 during sleep time. Respiratory rate was 60 during awake time and 20 during sleep time. Periodic leg movements showed total number of 74 with no arousals and PLMS index 17.3 per hour and number of periodic leg movement arousal index was 0. Respiratory data showed total number of apneas and hypopneas of 9 with no apneas and 9 hypopneas. Apnea index was 0 per hour and apnea-hypopnea index was 2.1 per hour. Arousal index was 0.5 per hour. Total number of REM events was 8. O2 saturation showed 1 event with O2 saturation between 80-85%, 18 events with O2 saturation between 85-90%, 29 events with O2 saturation between 90-95%. The longest respiratory event was 13.2 seconds and the lowest desaturation was 82%. Snoring was reported to be 1-2/10.

IMPRESSION: This test shows:
1. Poor sleep efficiency.
2. Disturbed sleep architecture.
3. Mild periodic leg movement, that was clear would not interfere with the patient’s sleep because there was no awakening.
4. No obstructive or central sleep apnea.
5. Few events with desaturation during the night.
