A primary care doctor reads the first screen and knows the severity and the next step. Everything below the cover is for the doctor who wants depth. All values are placeholder data.

Home sleep test report

EEG + cardiopulmonary · 3 nights requested · Scored and interpreted

Patient: Denise R. · 56 · F
Ordering: Primary care (placeholder)
Nights: Mar 2–4, 2027
Reported: Mar 9, 2027

Severity

Moderate obstructive sleep apnea

18.3 breathing events per hour of EEG-confirmed sleep (AHI, 3% rule)

Recommended next step

Discuss treatment with the patient. The interpreting physician recommends a PAP therapy trial.

Refer to sleep medicine if the patient declines PAP or does not tolerate it.

of EEG-confirmed sleep, out of 15 h 18 m in bed on usable nights.

Consistent

Night 2 AHI 18.5 · Night 3 AHI 18.0. Same severity band both nights.

Findings, ranked by clinical significance

Obstructive events. AHI 18.3 per hour of sleep. Events are worse on the back (AHI 31.2 supine vs 9.4 non-supine).
Oxygen. Lowest SpO₂ 82%. Time below 90%: 4.1% of sleep.
Fragmented sleep. Arousal index 24 per hour. The EEG shows the patient woke 31 times; 58% of those wakings followed a breathing event.
Central events: low. Central apnea index 0.4. No sign of a central pattern.

What to tell the patient

"Your breathing stopped or got shallow about 18 times an hour while you slept."
"That is in the moderate range. It can explain the snoring and the daytime sleepiness."
"It is treatable. The usual first step is a mask that keeps your airway open at night."

Why the number is trustworthy

EEG measured real sleep, so the index uses sleep time

Denise spent 15 h 18 m in bed across the two usable nights but slept 11 h 30 m. A home test without EEG cannot tell sleep from lying awake, so it divides events by total recording time. The 3 h 48 m she lay awake would have diluted her index into the mild range.

Same 210 events, different denominator. AASM guidance notes that home tests without sleep measurement use monitoring time and may underestimate severity (Kapur et al., JCSM 2017). Values are illustrative.

Average of nights 2 and 3.
Measure	Value	What it says
Sleep efficiency	75%	A quarter of time in bed was awake.
Sleep onset latency	26 min	Normal time to fall asleep.
Wake after sleep onset	1 h 22 m	Long, broken by many short wakings.
Arousal index	24 / h	Fragmented sleep.

REM latency	94 min	Within typical range.

Methods

Devices: EEG headband and cardiopulmonary monitor (nasal pressure, effort belt, pulse oximetry). Scoring: hypopneas with ≥3% desaturation or EEG arousal. Scored by a registered sleep technologist and interpreted by a board-certified sleep physician (placeholders). Regulatory labeling, indications for use, and signature blocks would appear here unchanged.
