SLEEP STUDY REPORT

Patient: [Full name, date of birth, sex]
Record number: [Medical record number]
Study date: [Night of the study]
Study type: [Diagnostic polysomnogram, split-night, CPAP or bilevel titration, or home sleep apnea test]
Location: [Sleep laboratory, or the patient's home]
Referring clinician: [Name and specialty]
Scored by: [Sleep technologist name and credential]
Interpreting physician: [Name and credentials]
Report date: [Date]

REFERRAL AND HISTORY
Referral question: [What the referring clinician needs to know]
Symptoms: [Snoring, witnessed apneas, sleepiness, waking short of breath, insomnia, leg symptoms, or behaviors in sleep]
Epworth Sleepiness Scale: [Score out of 24]
Relevant history: [BMI, neck size, and conditions such as heart failure, atrial fibrillation, stroke, lung disease, or opioid use]
Study night: [Medicines, alcohol, and caffeine that evening, and whether sleep was typical for the patient]

RECORDING
Channels: [In-lab: EEG, EOG, chin and leg EMG, ECG, airflow, effort, oximetry, position, snoring, and video. Home test: device type and channels]
Times: [Lights off and lights on, total recording time, or valid monitoring time on a home test]
Scoring rules: [AASM scoring manual version, and the hypopnea rule: 3% desaturation or arousal, or 4% desaturation]
Technical quality: [Adequate, or signal loss, how long, and how it was handled]
Technologist notes: [Events observed, interventions, and the patient's comments in the morning]

SLEEP ARCHITECTURE
Total sleep time: [Minutes, or not measured on a home test]
Sleep efficiency: [Percent of time in bed spent asleep]
Sleep latency and REM latency: [Minutes for each]
Stages: [N1, N2, N3, and REM as a percent of total sleep time]
Wake and arousals: [Wake after sleep onset in minutes; arousal index per hour]

RESPIRATORY EVENTS
AHI or REI: [Events per hour of sleep, or REI per hour of monitoring time on a home test]
Event types: [Obstructive, central, and mixed apneas; obstructive and central hypopneas; central events as a share of all events]
Position: [AHI supine and non-supine, with the time in each]
REM and NREM: [AHI in REM and in NREM sleep, or not measured on a home test]
Breathing patterns: [Cheyne-Stokes breathing, hypoventilation, snoring, or none]

OXYGEN SATURATION
Baseline: [Awake saturation before sleep]
Nadir: [Lowest saturation]
Time below 90%: [Minutes, and percent of sleep or monitoring time]
Oxygen desaturation index: [Desaturations per hour, with the threshold used]

HEART RHYTHM, LIMB MOVEMENTS, AND BEHAVIORS
ECG: [Rhythm, rate range, pauses, and arrhythmias, or pulse rate only on a home test]
Periodic limb movements: [PLM index per hour, and how many caused arousals]
Behaviors: [Findings on video such as dream enactment, REM sleep without atonia, parasomnia, or seizure-like events, or none]

PAP TITRATION, IF DONE
Device and mask: [CPAP or bilevel, backup rate if used, mask type and size]
Pressures: [Starting and highest pressure, and the AHI at each level]
Best pressure: [Pressure that controlled events, whether it was tested supine and in REM, or not reached]
Residual events: [Central events that persisted or emerged, leak, and comfort]

INTERPRETATION
Diagnosis: [Normal study, obstructive sleep apnea, central sleep apnea, or another finding]
Severity: [Adults: mild, AHI 5 to 14; moderate, 15 to 29; severe, 30 or more]
Pattern: [Positional, REM-related, or Cheyne-Stokes breathing]
Other findings: [Oxygen, rhythm, limb movement, or behavior findings that matter]
Limits: [Short sleep, little REM or supine sleep, home test underestimation, or signal loss]

RECOMMENDATIONS
Treatment: [CPAP or auto-CPAP with pressures, oral appliance, positional therapy, surgical referral, or other]
Further testing: [Titration, in-lab study, MSLT, a study on treatment, or none]
Related care: [Weight, alcohol, sedating medicines, heart failure, or other conditions]
Driving and safety: [Advice given about drowsy driving and safety-sensitive work]
Follow-up: [Sleep clinic visit and device download, and when]
