What is a Level 3 or Type III home sleep apnoea test?
A Level 3 Home Sleep Apnoea Test, also called a Type III HSAT, is a limited-channel overnight breathing study performed in the patient’s home. It records selected respiratory and oxygen-related signals while the patient follows their usual sleep routine.
The test is mainly used to investigate suspected obstructive sleep apnoea in appropriately selected patients. It may record airflow, respiratory effort, blood-oxygen saturation, pulse or heart-rate trend, snoring and body position where supported by the selected device configuration.
Level 3 is not full polysomnography. It does not record the complete EEG, EOG and chin-muscle signal set required for full sleep staging. Because actual sleep time is generally not directly measured, the report commonly uses a Respiratory Event Index based on usable recording time rather than an EEG-confirmed total sleep time.
Why choose Okto for a Level 3 home sleep test?
The usefulness of a home sleep study depends on appropriate patient selection, reliable signal collection, careful data review and responsible clinical interpretation. Okto provides more than equipment delivery by coordinating a professionally installed and doctor-governed testing workflow.
Biomedical engineer installation
A trained biomedical engineer performs the home setup—not an untrained delivery person who only drops off the recorder.
Study-appropriate placement
The Level 3 airflow, effort and oxygen-related sensors are positioned carefully for the selected equipment configuration.
Signal-quality verification
Connected sensors and recording status are checked before the biomedical engineer leaves the patient’s home.
Post-installation biocalibration
Short patient actions help verify that the connected physiological signals respond appropriately before recording begins.
Clear patient guidance
Patients receive instructions on recorder care, sleeping position, sensor protection and what to do if a sensor becomes loose.
Defined disinfection protocol
Reusable equipment and applicable components are cleaned and disinfected according to Okto’s defined protocol between patients.
Equipment pickup
Okto arranges equipment collection after the overnight recording for secure data download and quality review.
Doctor-governed reporting
Technology-assisted screening is followed by human quality review, specialist manual scoring and final interpretation under sleep-medicine doctor oversight.
Quality-controlled recording, scoring and interpretation
Doctor-Governed Sleep Study Reporting
A sleep study is only as useful as the quality of its recording, scoring and clinical interpretation. Okto combines biomedical engineer-led home installation with signal verification, post-installation biocalibration, specialist manual scoring and a structured, doctor-governed reporting process.
- Biomedical engineer-led home installation
- Study-appropriate Level 3 sensor placement
- Signal-quality verification before monitoring begins
- Post-installation biocalibration to confirm sensor response and recording quality
- Technology-assisted screening to organise recorded data and support quality review
- Human review of signal quality, artefacts, respiratory events and recorded patterns
- Manual scoring by a trained sleep-scoring specialist
- Final clinical interpretation and signed report under sleep-medicine doctor oversight
- Defined escalation workflow when potentially significant findings are identified
- The final diagnosis and treatment decision remain with the patient’s treating doctor
Technology supports study organisation, quality review and event triage. It does not independently diagnose sleep apnoea and does not replace manual specialist scoring, human verification or doctor oversight.

What is post-installation biocalibration?
Biocalibration is a practical signal check performed after the Level 3 sensors are connected. Depending on the recorder and connected sensors, the biomedical engineer may ask the patient to perform short actions such as taking a normal breath, taking a deeper breath, briefly changing position or making another simple movement.
The purpose is to check whether the relevant recorded signals respond in an appropriate way before the overnight study begins. This may help identify an obvious connection or placement concern while the engineer is still present.
Biocalibration does not guarantee a perfect recording and cannot prevent every possible sensor issue. A sensor may still shift or loosen while the patient is asleep.
What may the Level 3 sleep study measure?
The exact signal set depends on the selected Level 3 recorder and configuration. Applicable measurements may include:
- Airflow: records changes in breathing through an appropriate airflow sensor.
- Respiratory effort: records chest and abdominal breathing effort where the configured effort sensors are available.
- Blood-oxygen saturation: tracks overnight SpO₂ trends and oxygen desaturation events.
- Pulse or heart-rate trend: records pulse-related changes during the monitoring period.
- Snoring: records snoring-related information where supported.
- Body position: records sleep position where the selected device supports this signal.
- Respiratory events: supports identification and scoring of apnoea and hypopnoea patterns from usable respiratory data.
Who may be considered for a Level 3 OSA test?
A Level 3 test may be considered for suitable adults with symptoms or clinical features suggesting obstructive sleep apnoea. These may include:
- Loud or habitual snoring
- Witnessed pauses in breathing during sleep
- Choking or gasping during sleep
- Excessive daytime sleepiness
- Morning headaches or dry mouth
- Poor concentration or non-restorative sleep
- Frequent night-time awakenings
- High blood pressure with suspected sleep apnoea
Level 3 testing is not suitable for every patient. A treating doctor may recommend Level 2 home polysomnography or an attended laboratory study when another sleep disorder is suspected, when the medical history is complex, when significant comorbidities are present or when a previous Level 3 study is negative or inconclusive despite ongoing symptoms.
Strengths of Level 3 testing
- Performed in the patient’s usual sleep environment
- Focused assessment of sleep-related breathing signals
- Less complex sensor arrangement than full polysomnography
- May be appropriate for selected adults with suspected OSA
- Professional installation and signal checks at home
When a different study may be advised
- Suspected sleep disorder other than uncomplicated OSA
- Need for EEG-based sleep staging
- Complex neurological, cardiac, respiratory or neuromuscular history
- Significant insomnia or unusual sleep behaviours
- Negative or inconclusive Level 3 study despite persistent symptoms
- Insufficient usable recording data
A higher-level test is not automatically better for everyone. The appropriate test depends on symptoms, suspected sleep disorder, medical history, comorbidities, the clinical question and the treating doctor’s recommendation.

Equipment cleaning and disinfection
Reusable sleep-study equipment and applicable reusable components are cleaned and disinfected according to Okto’s defined protocol between patients. This supports responsible equipment handling and consistent service quality.
Single-use or disposable components are handled separately and are not described as reusable. The term “sterile” is not used unless a specific item and process are genuinely sterile.
What may be included in the Level 3 report?
Exact report contents depend on the connected Level 3 sensors, successful recording of those signals and the amount of usable data. The structured digital report may include:
- Total recording time and usable evaluation time
- Respiratory Event Index, as applicable
- Observed apnoea and hypopnoea patterns
- Oxygen saturation trends and desaturation events
- Snoring patterns where recorded
- Body-position-related findings where supported
- Pulse or heart-rate trends
- Signal-quality observations, artefacts and recording limitations
- Clinical impression and recommendations under doctor oversight
Technology-assisted screening may help organise recorded data and support quality review. It does not independently diagnose the patient. The study undergoes human verification and manual scoring by a trained sleep-scoring specialist before final clinical interpretation and signing under sleep-medicine doctor oversight.
Report turnaround is confirmed at booking and begins after successful equipment pickup, data download and confirmation that sufficient usable recording data is available. If the recording is technically incomplete, the team may recommend repeating part or all of the study before the report is finalised.
Safety during a home sleep study
A home sleep study is a diagnostic recording and is not a live emergency-monitoring service.
The recorder is not continuously watched as live clinical surveillance and does not provide an emergency response. For severe breathlessness, persistent chest pain, collapse, bluish discolouration, severe confusion or another medical emergency, seek urgent medical help immediately. Do not wait for Okto, equipment pickup or the sleep-study report.
