Airflow
Nasal / oral airflow
A small sensor under the nose senses the air moving in and out as you breathe.
Why it matters
Reduced or absent airflow during sleep is one of the key events a sleep assessment looks for. These changes can affect oxygen levels and sleep quality.
Recorded when
Typically recorded in both focused home assessments and comprehensive studies, where clinically appropriate.
Breathing effort
Chest & abdomen effort
A soft belt around the chest or abdomen senses whether your body is still trying to breathe.
Why it matters
It separates a pause where the body keeps trying to breathe from one where the effort stops. Clinically those mean different things.
Recorded when
Typically recorded in both focused home assessments and comprehensive studies, where clinically appropriate.
Blood oxygen
Oxygen saturation (SpO2)
A clip on the finger shines light through the skin to estimate how much oxygen your blood is carrying.
Why it matters
Changes in oxygen levels during sleep can be one of the signals evaluated when assessing sleep-disordered breathing.
Recorded when
Typically recorded in both focused home assessments and comprehensive studies, where clinically appropriate.
Heart rate
Pulse rate (BPM)
The same finger sensor records your pulse through the night.
Why it matters
Heart rate often shifts around a breathing event, which adds context to the rest of the recording.
Recorded when
Typically recorded in both focused home assessments and comprehensive studies, where clinically appropriate.
Body position
Position & movement
The recording unit senses whether you are on your back, side or front, and how much you move.
Why it matters
Some people have far more events on their back than on their side, and that can change what is advised.
Recorded when
Recorded where the device supports it. [VISIONX CONFIRM: whether the VisionX device records position.]
Brain activity
EEG
Small sensors on the scalp record brain activity so sleep stages can be scored.
Why it matters
It shows how much you actually slept, rather than how long the device was recording - which changes how some numbers are calculated.
Recorded when
Only in a comprehensive sleep study. A focused home assessment does not record EEG.
Eye movement
EOG
Sensors beside the eyes pick up the small movements your eyes make during sleep.
Why it matters
Eye movement is one of the things used to tell REM sleep apart from the other stages.
Recorded when
Only in a comprehensive sleep study. A focused home assessment does not record EOG.
Muscle activity
EMG
Sensors on the chin and sometimes the legs record muscle tone and leg movements.
Why it matters
Muscle tone changes with sleep stage, and repeated leg movements can be relevant to how you sleep.
Recorded when
Only in a comprehensive sleep study. A focused home assessment does not record EMG.

Check your sleep risk
Eight questions about snoring, tiredness and a few background factors. Your answers stay in your browser - nothing is sent to us or saved.
See the 8 questions and how they are scored
- Do you snore loudly? Loud enough to be heard through a closed door, or loud enough that someone next to you nudges you to stop.
- Do you often feel tired, fatigued or sleepy during the day? For example, struggling to stay awake while reading, sitting in a meeting, or waiting in traffic.
- Has anyone seen you stop breathing, choke or gasp during your sleep? A partner or family member is usually the one who notices this.
- Do you have high blood pressure, or are you being treated for it? Count it as yes if you take medicine for blood pressure, even if it is well controlled now.
- Is your body mass index above 35? BMI relates weight to height. If you are not sure, use the calculator - it works entirely in your browser.
- Are you older than 50?
- Is your neck size large? Measured around the Adam's apple: 43 cm (17 inches) or more for men, 41 cm (16 inches) or more for women. Your shirt collar size is a good guide.
- Were you assigned male at birth? The instrument scores this because sleep-disordered breathing is diagnosed more often in men. It is one factor among eight, not a verdict.
Each "yes" scores one point, out of 8. 0–2: Lower apparent risk. 3–4: Elevated risk. 5–8: Higher risk.
Screening items and scoring follow the published STOP-Bang questionnaire (Chung F et al., University Health Network, University of Toronto). Used here for education and screening only.
This is an educational screening check, not a diagnosis. A questionnaire cannot determine whether you have a sleep disorder. The appropriate test and its interpretation should be decided by a qualified healthcare professional based on your symptoms and medical history.
Why it matters
You sleep every night.
But are you actually resting?
Breathing, oxygen and sleep quality are linked. When breathing is interrupted often enough, the effects can show up the next day rather than at night - which is why the problem is easy to miss.

Signs people tend to notice
Select a symptom to read more.
Loud snoring
Snoring loud enough to be heard through a closed door, or loud enough that a partner moves to another room.
Common, and not always a problem on its own - but worth mentioning alongside other symptoms.
Witnessed breathing pauses
Someone has seen you stop breathing during sleep, or you wake with a gasp or a choking sensation.
One of the more specific things to raise with a healthcare professional.
Waking unrefreshed
You sleep a full night and still wake up feeling as though you barely slept.
Has many possible causes; disturbed breathing is one of them.
Daytime sleepiness
Falling asleep during quiet activities - reading, sitting in a meeting, waiting in traffic.
If you have ever felt sleepy while driving, raise it with a doctor promptly.
Morning headache
A dull headache in the first hour or two after waking, easing through the morning.
Sometimes reported alongside disturbed night-time breathing.
Dry mouth on waking
Waking with a very dry mouth or sore throat, often from breathing through the mouth all night.
Also caused by blocked nasal breathing and by some medicines.
Poor concentration
Losing your thread mid-task, re-reading the same line, or feeling foggy through the afternoon.
Non-specific, but often the reason people finally seek help.
Irritability & low mood
Feeling short-tempered or flat in a way that eases when you happen to sleep well.
Worth mentioning to a healthcare professional, who can consider the wider picture.
Sometimes the person who notices your sleep problem isn't you.
I sleep fine.
You
You stopped breathing.
Your partner
People are often unaware of breathing interruptions, gasping or choking during their own sleep. A partner or family member may have noticed something worth mentioning to a healthcare professional.
The signals
Your body keeps talking while you sleep.
A sleep assessment records selected physiological signals through the night. Which signals are recorded depends on the study - not every test records every channel.
Breathing effort
Chest & abdomen effort
A soft belt around the chest or abdomen senses whether your body is still trying to breathe.
Blood oxygen
Oxygen saturation (SpO2)
A clip on the finger shines light through the skin to estimate how much oxygen your blood is carrying.
Heart rate

You don't have to perform for the test.
The goal is to sleep as normally as possible. The equipment records selected physiological signals while you sleep. You may notice the sensors, especially during the first few minutes, but you should try to follow your normal bedtime routine.
Before bed
Eat, wash and wind down as you normally would. Avoid lotions or oils on the finger and face so the sensors sit properly.
During setup
The sensors go on a few minutes before you sleep, following the instructions provided with the device.
While sleeping
Sleep in your usual position. You can turn over, and you can get up to use the bathroom - the recording continues.
When you wake
Remove the sensors and follow the agreed return instructions. Note anything unusual about the night - it helps whoever reviews the recording.
Step by step
How a home sleep assessment works
From the first conversation to the discussion about what your result means.
-
01
Assessment
We talk through your symptoms and history, and a clinician decides whether home testing is appropriate for you.
-
02
Setup
The equipment is prepared and you are shown exactly how to fit it, with written instructions to keep.
-
03
Sleep
You use the equipment overnight, at home, in your own bed.
-
04
Morning
You remove the sensors and follow the agreed collection or return instructions.
-
05
Data review
The recording is checked for technical quality and then reviewed clinically, following the service workflow.
-
06
Report
You receive a report written to be understandable, not just technically complete.
-
07
Next step
You discuss the result and appropriate care with a qualified healthcare professional.
Choosing
The right test depends on the person.
Home testing suits many people, but not everyone. Some situations call for a more comprehensive evaluation in a sleep laboratory.
Home sleep assessment
Appropriate for selected patients
- Your own bed, your own routine
- No overnight stay away from home
- Convenient for people with straightforward symptoms
- Records a focused set of signals
Laboratory sleep study
May be more appropriate when
- The clinical picture is complex
- Another sleep disorder is suspected
- A home test was inconclusive or technically inadequate
- Your clinician decides a fuller evaluation is necessary
Neither is universally better. Which one fits you is a clinical judgement, based on your symptoms and medical history.
Guided
Which assessment may be appropriate for you?
Three questions. The answer is a suggested starting point for a conversation, not a clinical decision.
Focused home sleep apnea assessment
Records a focused set of breathing-related signals overnight at home. Appropriate only when the clinical criteria for home testing are met.
Book a Sleep AssessmentComprehensive sleep assessment
Records more physiological signals, where available, for situations that need a fuller picture than a focused home test provides.
Book a Sleep AssessmentClinical consultation first
A conversation with a qualified healthcare professional before any test, so the right assessment is chosen for your situation.

Select a term to see what it means.
- AHI
- Apnea-Hypopnea Index - the average number of apneas and hypopneas per hour of sleep or recording time, depending on the test and how it is calculated.
- SpO2
- Oxygen saturation - an estimate of how much oxygen your blood is carrying, sampled continuously through the night.
- ODI
- Oxygen Desaturation Index - the average number of times per hour that oxygen saturation fell by a set amount from its recent baseline.
- Heart rate
- Your pulse through the night, recorded by the same finger sensor that estimates oxygen.
- Airflow
- The movement of air in and out through the nose and mouth, sensed at the nostrils.
- Recording quality
- How much of the night produced usable signal. A report says this plainly, because a recording with too little usable data cannot be interpreted reliably.
AHI, explained simply.
AHI stands for Apnea-Hypopnea Index. It represents the average number of apneas and hypopneas per hour of sleep or recording time, depending on the test and how it is calculated.
AHI is important, but it is not the entire clinical picture. Symptoms, oxygen levels, medical history and other findings all matter, which is why a number on its own is not a diagnosis.

FAQ
Questions people ask us
Before the test
What is a sleep test?
A way to understand what your body is doing while you sleep. Sensors record selected signals - such as airflow, breathing effort and blood oxygen - through the night, and a clinician reviews what was recorded.
Why would I need one?
Usually because of symptoms such as loud snoring, witnessed breathing pauses, or persistent daytime sleepiness - or because a healthcare professional has suggested it.
Do I need a doctor's recommendation?
Home testing is appropriate for selected patients, so a clinical assessment comes first. [VISIONX CONFIRM: whether VisionX requires a referral before booking.]
Can I take the test at home?
For many people, yes. Whether home testing is suitable for you depends on your symptoms and medical history.
During the test
Will it hurt?
No. The sensors sit on the skin - a clip on a finger, a light tube under the nose, a soft belt around the chest. Nothing breaks the skin.
Can I move around?
Yes. Turn over, change position, sleep how you normally sleep.
What if I don't sleep well?
That happens, and it is usually still a usable recording. If too little was recorded to interpret, whoever reviews it will say so and advise on what to do next.
Can I use the bathroom?
Yes. Follow the instructions provided with your device for anything that needs unclipping, and refit it when you return to bed.
Results
How long does the report take?
[VISIONX CONFIRM: report turnaround time.]
Who reviews the result?
The recording is checked for technical quality and then interpreted by a qualified clinician. [VISIONX CONFIRM: name and credentials of the reviewing clinician.]
What is AHI?
The Apnea-Hypopnea Index: the average number of apneas and hypopneas per hour of sleep or recording time, depending on the test and how it is calculated. It is one important number among several, not a diagnosis on its own.
What does low oxygen mean?
Reports usually describe how far and how often oxygen saturation fell during the night. What that means for you depends on the rest of the recording and on your medical history, which is why a clinician interprets it rather than a number alone.
What if the result is inconclusive?
It can happen - a sensor comes loose, or too little of the night is usable. The usual options are repeating the recording or moving to a more comprehensive study. [VISIONX CONFIRM: repeat-test policy and any cost.]
Clinical
Is home testing appropriate for everyone?
No. It suits selected patients with a fairly straightforward clinical picture. Other situations need a laboratory study or a different evaluation.
When is a laboratory study needed?
When the clinical situation is complex, when another sleep disorder is suspected, when a home test was inconclusive or technically inadequate, or when your clinician judges that a fuller evaluation is necessary.
Can children take this test?
Sleep testing in children is handled differently from adults. [VISIONX CONFIRM: whether VisionX offers paediatric sleep testing and from what age.]
What if I have another sleep disorder?
Tell whoever assesses you. A focused home test is aimed at sleep-disordered breathing; other conditions may need a different or additional evaluation.
