Choose a Level 3 home sleep apnoea test or a more detailed Level 2 unattended home polysomnography study—with biomedical engineer installation, signal verification, post-installation biocalibration, specialist manual scoring and doctor-governed reporting.
Biomedical engineer installed. Signals verified. Manually scored. Doctor interpreted.
The biomedical engineer charge covers home installation, study-appropriate skin preparation, sensor placement, signal-quality verification, post-installation biocalibration and patient guidance. Equipment pickup, manual specialist scoring and a signed digital report are included in the applicable test charge.
Level 3 and Level 2 sleep-study options
Level 3 and Level 2 studies are different tests designed to answer different clinical questions. Level 3 is a limited-channel home sleep apnoea test. Level 2 is unattended polysomnography performed at home with sleep staging and a wider range of physiological signals.
A higher-level test is not automatically better for every patient. The appropriate study depends on symptoms, the suspected sleep disorder, medical history, relevant comorbidities, the clinical question and the treating doctor’s recommendation.

Why choose Okto for a home sleep study?
The usefulness of a home sleep study depends on correct test selection, careful sensor placement, usable overnight signals, responsible scoring and appropriate clinical interpretation. Okto coordinates these quality steps through a biomedical engineer-led and doctor-governed workflow.
Biomedical engineer installation
A trained biomedical engineer performs the home setup—not an untrained delivery person who only drops off the recorder.
Proper skin preparation
The skin is prepared as required before sensors and electrodes are placed to support adhesion and reduce avoidable artefact.
Study-appropriate sensor placement
Only sensors relevant to the selected Level 3 or Level 2 configuration are applied and connected.
Signal-quality verification
Connected signals and recording status are checked before the biomedical engineer leaves the patient’s home.
Post-installation biocalibration
Short patient actions are used to confirm that the connected signals respond appropriately before overnight recording begins.
Patient guidance
Patients receive clear instructions on equipment 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.
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
- Proper skin preparation and study-appropriate 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 sleep-related 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 or another sleep disorder 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 sensors are connected. Depending on the selected study and its sensors, the biomedical engineer may ask the patient to perform short actions such as opening and closing the eyes, looking in different directions, taking a breath, moving a limb, changing position or making another simple movement.
The aim is to check whether the relevant recorded signals respond in the expected way before monitoring begins. This additional quality-control step may help identify connection or placement concerns before the patient goes to sleep.
Biocalibration does not guarantee a perfect overnight recording and cannot prevent every possible sensor issue. Sensors may still loosen or shift during sleep, which is why patients also receive device-specific guidance.
What may the sleep study measure?
Level 3 home sleep apnoea test
Level 3 is a limited-channel study. Depending on the selected equipment configuration and usable signals, it may record:
- Airflow
- Chest and abdominal respiratory effort
- Blood-oxygen saturation
- Pulse or heart-rate trend
- Snoring
- Body position where supported
- Apnoea and hypopnoea events estimated from recorded breathing data
Level 3 does not provide full EEG-based sleep staging. Because actual sleep time may not be directly measured, the report may use a Respiratory Event Index based on usable recording time.
Level 2 home polysomnography
Level 2 uses a wider signal set. Depending on the configured channels and successfully recorded data, it may include:
- EEG brain-wave activity for sleep staging
- EOG eye-movement signals
- Chin-muscle activity
- ECG or heart-rate signal
- Airflow and respiratory effort
- Blood-oxygen saturation and pulse trend
- Snoring and body position
- Limb-movement signals where configured
- Sleep stages, arousals and respiratory events where supported by usable data
Blood-pressure or ABPM recording is not included as a standard sleep-study parameter. Where separately available and clinically requested, it should be treated as an optional add-on and not as continuous blood-pressure monitoring unless the specific device provides that capability.

- Note relevant events or unusual sleep interruptions accurately.
- Sleep in your usual position unless your treating doctor advises otherwise.
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 process is intended to support safe equipment handling and consistent service quality.
Single-use or disposable components are handled separately and are not represented as reusable. The term “sterile” is not used unless a particular item and its validated process are genuinely sterile.
What may be included in the sleep-study report?
Exact report contents depend on the selected test level, connected sensors, successful recording of those signals and the amount of usable data. Depending on the study, the report may include:
- Recording time and technical recording observations
- Total sleep time where sleep staging is supported
- Sleep efficiency and sleep-stage distribution for a usable Level 2 study
- Apnoea–Hypopnoea Index or Respiratory Event Index, as applicable
- Oxygen saturation trends and desaturation events
- Snoring patterns
- Body-position-related findings where recorded
- Heart-rate trends
- Respiratory-event patterns
- Arousal information where supported
- Limb-movement findings where supported
- Artefacts, signal limitations and other technical observations
- Clinical impression and recommendations under doctor oversight
Technology-assisted screening supports study organisation and quality review. It is followed by human verification, manual specialist scoring and final clinical interpretation under sleep-medicine doctor oversight. Technology does not independently diagnose the patient.
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 the service 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.

Who installs the sleep-study equipment?
A trained biomedical engineer performs skin preparation, study-appropriate sensor placement, signal-quality verification and post-installation biocalibration before providing equipment-care guidance.
What is sleep-study biocalibration?
Biocalibration involves asking the patient to perform short actions, depending on the test and connected sensors, to check whether the recorded signals respond appropriately before monitoring begins. It does not guarantee that no sensor issue will occur during sleep.
Is the sleep-study report manually scored and doctor governed?
Yes. Technology-assisted screening supports study organisation and quality review, followed by human verification, manual scoring by a trained sleep-scoring specialist and final interpretation with a signed report under sleep-medicine doctor oversight.
Is a home sleep study watched live?
No. A home sleep study is a diagnostic recording and is not a live emergency-monitoring service. Recorded data is reviewed after successful equipment pickup and data download.
Can a normal home sleep study exclude every sleep disorder?
No. A normal or inconclusive home study does not always exclude a sleep disorder. Results may be affected by sensor displacement, artefacts, unusual sleep, inadequate recording time or insufficient usable data. Repeat testing or a different study may be advised.
When will the sleep-study report be available?
Report turnaround is confirmed at booking and begins after successful equipment pickup, data download and confirmation that sufficient usable recording data is available.
