Airflow
Nasal / Oral airflow
A small sensor under the nose senses the air moving in and out as you breathe.
Sleep assessment Nepal
A clinically guided sleep assessment can help uncover breathing interruptions, oxygen changes and other signals that may be affecting how you sleep and how you feel during the day.
A typical night can include moments your body struggles to breathe.

Waveforms are illustrative, not recorded patient data.
Interactive
Every night, your body tells a story through signals. Explore each signal to understand what your sleep assessment can look for.

Nasal / Oral airflow
Recorded in both home studies
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 signs we look for when evaluating sleep-disordered breathing.
What it can help show
Example airflow pattern
Recorded in both the focused home sleep apnea assessment and the comprehensive home sleep study.
Chest & abdomen effort
Recorded in both home studies
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.
What it can help show
Example breathing effort pattern
Recorded in both the focused home sleep apnea assessment and the comprehensive home sleep study.
Oxygen saturation (SpO2)
Recorded in both home studies
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.
What it can help show
Example blood oxygen pattern
Recorded in both the focused home sleep apnea assessment and the comprehensive home sleep study.
Pulse rate (BPM)
Recorded in both home studies
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.
What it can help show
Example heart rate pattern
Recorded in both the focused home sleep apnea assessment and the comprehensive home sleep study.
EEG
Comprehensive home study only
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.
What it can help show
Example brain activity pattern
Recorded in the comprehensive home sleep study only. The focused home sleep apnea assessment does not record it.
EOG
Comprehensive home study only
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.
What it can help show
Example eye movement pattern
Recorded in the comprehensive home sleep study only. The focused home sleep apnea assessment does not record it.
EMG
Comprehensive home study only
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.
What it can help show
Example muscle activity pattern
Recorded in the comprehensive home sleep study only. The focused home sleep apnea assessment does not record it.

Eight questions about snoring, tiredness and a few background factors. Your answers stay in your browser - nothing is sent to us or saved.
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
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.
Select a symptom to read more.
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.
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.
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.
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.
A dull headache in the first hour or two after waking, easing through the morning.
Sometimes reported alongside disturbed night-time breathing.
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.
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.
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.
I sleep fine.
You
I noticed you stopped breathing for a moment.
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
A sleep assessment records selected physiological signals through the night. Which signals are recorded depends on the study - not every test records every channel.

The equipment
Select a part of the device to see what it does.
Illustrative schematic of a portable sleep-test monitoring device, not a photograph of the equipment.
A light cannula that rests under the nose and senses the air you move.
A soft elastic belt that senses whether your chest is still working to breathe.
The small box that stores the night. It sits on the chest or beside the bed.
A soft clip that estimates blood oxygen and records your pulse.
Used only in the comprehensive home sleep study, which adds sensors for brain activity, eye movement and muscle activity.
The equipment is a portable sleep-test monitoring device. The comprehensive home sleep study adds sensors for brain activity, eye movement and muscle activity.
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.
Follow the preparation instructions you are given for the test: avoid caffeine after 2 PM, avoid alcohol on the test day, skip daytime naps, wash your face and avoid creams or oils where the sensors will sit, wear loose comfortable sleepwear, and keep your overnight essentials ready.
The sensors go on a few minutes before you sleep, following the instructions provided with the device.
Sleep in your usual position. You can turn over, and you can get up to use the bathroom - the recording continues.
Remove the sensors and follow the agreed return instructions. Note anything unusual about the night - it helps whoever reviews the recording.
Step by step
From the first conversation to the discussion about what your result means.
We talk through your symptoms and history, and a clinician decides whether home testing is appropriate for you.
The equipment is prepared and you are shown exactly how to fit it, with written instructions to keep.
You use the equipment overnight, at home, in your own bed.
You remove the sensors and follow the agreed collection or return instructions.
The recording is checked for technical quality and then reviewed by a certified sleep specialist.
Your report is prepared and delivered with a 24–72 hour delivery target, written to be understandable, not just technically complete.
You discuss the result and appropriate care with a qualified healthcare professional.
Choosing
Home testing suits many people, but not everyone. Some situations call for a more comprehensive evaluation in a sleep laboratory.
Appropriate for selected patients
May be more appropriate when
Neither is universally better. Which one fits you is a clinical judgement, based on your symptoms and medical history.
Guided
Three questions. The answer is a suggested starting point for a conversation, not a clinical decision.
Records airflow, breathing effort, blood oxygen and heart rate overnight at home. Appropriate only where the clinical criteria for home testing are met.

The result
A readable summary of the night, with the numbers explained in plain language.
Select a term to see what it means.
AHI (Apnea-Hypopnea Index) counts apneas and hypopneas per hour of measured sleep, so it needs a study that records sleep itself. REI (Respiratory Event Index) counts the same events per hour of monitoring time, which is why a home sleep apnea test that does not record sleep stages reports REI rather than AHI. Your report uses the index that matches the study you had.
AHI, REI and related respiratory indices are important measurements, but no single number represents 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
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 certified sleep specialist reviews what was recorded.
Usually because of symptoms such as loud snoring, witnessed breathing pauses, or persistent daytime sleepiness - or because a healthcare professional has suggested it.
Home testing is appropriate for selected people, so a clinical assessment comes first. If a referral or order is needed for your situation, our team will explain that when you book.
For many people, yes. Whether home testing is suitable for you depends on your symptoms and medical history.
One night. The sensors go on shortly before you sleep and come off in the morning; the setup itself takes minutes.
Follow the preparation instructions you are given: avoid caffeine after 2 PM, avoid alcohol on the test day, skip daytime naps, wash your face and avoid creams or oils where the sensors will sit, wear loose comfortable sleepwear, and keep your overnight essentials ready.
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.
Yes. Turn over, change position, sleep how you normally sleep.
Yes. Follow the instructions provided with your device for anything that needs unclipping, and refit it when you return to bed.
That happens, and it is usually still a usable recording. If too little was recorded to interpret, the reviewer will say so and advise on what to do next.
Yes - that is the point. The recording is most useful when the night is as normal as possible, apart from the preparation instructions.
Refit it as shown in your instructions and carry on sleeping. Note it in the morning so the reviewer knows; a short gap usually does not spoil the recording.
Do not try to repair it. Note what happened and the time, and tell our team in the morning on +977 9812771487. If the recording cannot be interpreted, we will explain the options.
The delivery target is 24–72 hours after the recording is returned.
The recording is checked for technical quality and then reviewed by a certified sleep specialist through the sleep-testing provider.
The Apnea-Hypopnea Index: apneas and hypopneas per hour of measured sleep. It applies to studies that record sleep itself. It is one important number among several, not a diagnosis on its own.
The Respiratory Event Index: the same events counted per hour of monitoring time. A home sleep apnea test that does not record sleep stages reports REI rather than AHI. Your report uses the index that matches the study you had.
Reports 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.
The usual options are repeating the recording or moving to a more comprehensive study. A negative home test does not necessarily rule out sleep apnea when symptoms persist. Our team will explain what applies to you, including any cost, before anything is repeated.
The reviewer will say so plainly rather than interpret unusable data. Our team will then explain the options, which usually means repeating the night.
No. It suits selected people with a fairly straightforward clinical picture. Other situations need a laboratory study or a different evaluation.
When the clinical situation is complex, when another sleep disorder is suspected, when a home assessment was negative or inconclusive despite ongoing clinical suspicion, when it was technically inadequate, or when your clinician judges that a fuller evaluation is necessary.
Sleep testing in children is handled differently from adults. Contact our team to discuss whether a suitable pathway exists for your child.
Tell whoever assesses you. A focused home test is aimed at sleep-disordered breathing; other conditions may need a different or additional evaluation.
