Definition
SleepImage is an FDA-cleared home sleep study using cardiopulmonary coupling (CPC) analysis to quantify sleep quality.
-
Single-channel ECG-based
A single ECG derivation is analysed to derive respiratory and autonomic signals — no nasal cannula required.
-
FDA-cleared for OSA
Cleared as a home sleep apnoea test for detecting sleep-disordered breathing in adults and children.
-
Adult + paediatric
Validated across adults and paediatric populations, including school-age children too small for full PSG.
-
Repeat monitoring at low cost
Simple, wearable and low-burden — well suited to serial monitoring of treatment response.
-
Complements PSG and Nox T3
Not a replacement for in-lab polysomnography or Nox T3 in complex cases — a rapid, quantitative screen.
How it works
From consultation to structured plan — what happens, in order.
One consultant sleep physician from first appointment through to interpretation and plan.
- 01
Before
Sleep consultation
Symptom review with a consultant sleep physician — snoring, apnoea, daytime somnolence, paediatric presentation.
- 02
Before
Device fitted at home
The SleepImage recorder is couriered or collected. Simple self-application — no clinic visit required.
- 03
On the night
Overnight recording
A single night in your own bed. ECG signal captured continuously, with optional pulse oximetry.
- 04
On the night
CPC analysis
Cardiopulmonary coupling analysis derives sleep quality, stability and respiratory event data from the ECG.
- 05
After
Sleep-disordered breathing index
Apnoea–hypopnoea index (AHI), sleep quality index and central vs obstructive split are calculated.
- 06
After
Consultant report
A written report from a consultant sleep physician — with paediatric interpretation where relevant.
- 07
After
Structured plan
CPAP, MAD, ENT referral, weight-management or MDT review — the plan follows the numbers.
What it shows
What SleepImage measures.
From a single ECG derivation, SleepImage returns a quantitative sleep quality index alongside standard AHI and event classification.
-
Sleep quality index
A quantitative measure of stable, unstable and wake sleep across the night.
-
AHI events
Apnoea–hypopnoea index — the standard measure of sleep-disordered breathing severity.
-
Central vs obstructive
Distinguishes central from obstructive respiratory events, guiding therapy choice.
-
REM vs NREM cycles
Estimates REM and NREM distribution — useful when REM-related events dominate.
-
Paediatric OSA screening
Low-burden alternative to full PSG in children with suspected obstructive sleep apnoea.
-
CPAP response
Serial studies quantify how well CPAP is controlling events and improving sleep quality.
-
Post-adenotonsillectomy check
Objective post-surgical assessment in children after adenotonsillectomy for OSA.
-
Red flag: severe OSA in child — urgent ENT
Severe paediatric OSA warrants urgent ENT and paediatric sleep-medicine review.
Treatment options
What can follow a positive SleepImage study.
The right treatment depends on severity, event type and patient factors — the numbers guide the plan.
-
CPAP for OSA
Continuous positive airway pressure remains first-line for moderate-to-severe obstructive sleep apnoea.
-
Positional therapy
For supine-dominant OSA, devices and training that discourage supine sleep can materially reduce events.
-
Adenotonsillectomy
First-line surgical treatment for most children with obstructive sleep apnoea and adenotonsillar hypertrophy.
-
Mandibular advancement device (MAD)
Custom oral appliance option for mild-to-moderate OSA or CPAP-intolerant adults.
-
Weight loss + lifestyle
Weight reduction, alcohol timing and sleep hygiene reduce event burden and improve CPAP tolerance.
-
ASV
Adaptive servo-ventilation for selected central and complex sleep-disordered breathing (with cardiac caveats).
-
Sleep follow-up
Repeat SleepImage at 3–6 months to objectively confirm treatment response.
-
MDT review
Complex, paediatric or cardiac-comorbid cases discussed across sleep, ENT, cardiology and respiratory.
Red flags
When home testing isn’t enough.
Situations that need urgent escalation, MDT review, or a full in-lab polysomnogram rather than a home study alone.
-
Severe OSA in child
Severe paediatric OSA warrants urgent ENT and paediatric sleep-medicine referral.
-
Severe OSA + heart failure
Coexisting severe OSA and heart failure needs joint cardiology and sleep review.
-
Central sleep apnoea
A predominantly central pattern requires targeted work-up — cardiac, neurological and drug review.
-
Obesity hypoventilation
Daytime hypercapnia and hypoventilation need urgent respiratory input beyond home testing.
-
Occupational driving
HGV, PSV and commercial drivers with moderate-to-severe OSA carry statutory reporting duties.
-
Post-stroke OSA
OSA after stroke worsens recurrence risk — treatment should not be delayed.
-
Refractory hypertension
Hypertension resistant to three drugs is strongly associated with underlying OSA.
-
Complex parasomnia
Injurious or complex parasomnia usually warrants full in-lab polysomnography.
-
REM behaviour disorder
Suspected REM sleep behaviour disorder needs neurology-led video-PSG assessment.

Frequently asked
Everything we get asked about SleepImage.
Quick answers on what SleepImage is, how it compares with PSG and Nox T3, paediatric use, and reporting.
-
What is SleepImage?
SleepImage is an FDA-cleared home sleep study that uses cardiopulmonary coupling (CPC) analysis of a single ECG derivation to quantify sleep quality and detect sleep-disordered breathing in adults and children.
-
How is SleepImage different from a standard home sleep study?
Traditional home sleep studies rely on nasal flow, effort belts and oximetry. SleepImage derives respiratory and autonomic information from the ECG alone, giving a quantitative sleep quality index alongside AHI — with a simpler, lower-burden set-up.
-
Can SleepImage be used in children?
Yes. SleepImage is validated in paediatric populations and is widely used as a low-burden screen for obstructive sleep apnoea in school-age children who would tolerate a full in-lab study poorly.
-
When should I have a polysomnogram (PSG) or Nox T3 instead?
Full PSG or Nox T3 is preferred for complex parasomnia, suspected REM sleep behaviour disorder, seizure vs event differentiation, and where central sleep apnoea or ventilation problems need detailed characterisation.
-
How do I get results?
A consultant sleep physician reports the study and returns a structured plan, typically within a few working days of the recording.
-
Is SleepImage covered by insurance?
Cover for private sleep studies depends on your policy and clinic. We confirm with your insurer before booking.

In practice, in London
Why private sleepimage moves differently in London
With sleepimage, the London question is usually about report turnaround and the radiologist reading it — not whether the scan is available. Public provision for sleepimage is competent but constrained by capacity. Private London clinics tend to have shorter diaries and longer appointment slots, so you get the same specialists with more time. For people who’ve been going round in circles with primary care, that first proper conversation is often what shifts things.
The mechanics are straightforward: a consultant appointment, any tests done at a nearby CQC-registered site, and a written report back within a few days. London’s density of private diagnostics — Marylebone, the City, Chelsea, Canary Wharf — means most patients can find something that fits around work without a cross-town trek. For sleepimage specifically, the difference between a routine report and a sub-speciality read is where private care earns its keep.
The value of going through a concierge for sleepimage isn’t access — anyone with an insurer or a credit card can get a private appointment in London. The value is knowing which consultant reads this particular presentation best, which unit turns reports around fastest, and which pathway won’t hit a dead end if the findings point somewhere unexpected.
