What is sleep apnoea diagnosis and why it matters in Singapore

Sleep apnoea diagnosis is the medical process of confirming repeated abnormal breathing during sleep and grading how significant it is. A proper diagnosis matters because untreated sleep apnoea can affect daytime alertness, blood pressure, heart rhythm and quality of life.

Sleep apnoea includes obstructive sleep apnoea, where the airway narrows or collapses, and central sleep apnoea, where breathing effort becomes unstable because brain signalling is altered. These are different conditions, so the test and follow-up pathway may differ.

In Singapore, many people first seek help for loud snoring, witnessed pauses, morning headaches or non-refreshing sleep. Others are prompted to get checked after hypertension, obesity, atrial fibrillation or excessive daytime sleepiness is raised during a clinic review.

A clear sleep apnoea diagnosis helps a doctor decide whether you need lifestyle measures, ENT review, CPAP, pressure titration or a more detailed specialist work-up. For foundational reading, Comooz has sleep apnoea education guides.

When to suspect sleep apnoea: symptoms, risk factors and warning signs

You should suspect sleep apnoea when snoring is paired with choking, witnessed pauses, fragmented sleep or excessive daytime tiredness. Symptoms raise suspicion, but they do not confirm the diagnosis without a sleep study.

Common warning signs include loud habitual snoring, gasping, dry mouth on waking, morning headache, poor concentration, irritability and unrefreshing sleep. Some people mainly notice drowsiness in meetings, during commutes or while driving.

Doctors also assess risk factors for obstructive sleep apnoea. These include obesity, larger neck size, nasal obstruction, family history and male sex, although women and people who are not overweight can still have sleep apnoea.

It is more important to seek assessment when symptoms occur together with:

• hypertension

• type 2 diabetes

• atrial fibrillation

• resistant fatigue

• safety-sensitive work

• drowsy driving risk

Who this is for and who it is not for

This article is for adults in Singapore who want to understand how sleep apnoea diagnosis works, what tests are used and what results may mean. It is especially relevant if you have snoring plus sleepiness, witnessed breathing pauses or related medical risks.

This article is not a substitute for a doctor’s diagnosis. If central sleep apnoea, serious heart or lung disease, neurological disease, unusual nighttime behaviours or major insomnia symptoms are concerns, a sleep physician may prefer a more comprehensive assessment.

How doctors diagnose sleep apnoea step by step

Doctors diagnose sleep apnoea in a sequence: clinical review, examination, sleep study, interpretation and treatment planning. The aim is to determine whether the breathing problem is obstructive, central or mixed, and how severe it is.

First, the doctor takes a focused history. This includes snoring, witnessed apnoea, choking, insomnia symptoms, daytime sleepiness, medicines, alcohol use, shift work and medical conditions such as heart failure or neurological disease.

Second, the doctor examines airway and risk features. This may include weight, neck size, nasal airflow, jaw structure, tonsils and blood pressure.

Third, the doctor orders a sleep study. In Singapore, this may be a home sleep test or full polysomnography, depending on how straightforward or complex the case appears.

A home sleep test is a portable overnight test performed outside the lab. At Comooz, Type 3 home sleep testing is available on demand through the home sleep test service, while Type 2 home testing is arranged manually with a trained specialist.

Fourth, the study is interpreted by a doctor. The report looks at airflow reduction, respiratory effort, oxygen desaturation, pulse trends and the overall clinical context.

Fifth, the doctor discusses next steps. If obstructive sleep apnoea is confirmed, options may include CPAP, positional measures, weight management, ENT review or pressure titration. If central sleep apnoea is suspected, more specialist evaluation may be needed before choosing therapy.

Home sleep test vs in-lab polysomnography: what is the difference?

A home sleep test and in-lab polysomnography are both valid ways to investigate sleep apnoea, but they are not interchangeable in every case. A home sleep test is usually simpler and more convenient, while polysomnography is more comprehensive.

A Type 3 home sleep test usually focuses on breathing-related signals such as airflow, effort and oxygen levels. A Type 2 home sleep test is more elaborate and is arranged manually when a trained specialist setup is needed.

Polysomnography is the reference study when sleep stages, unusual events, limb movements, parasomnias or central breathing instability need closer review. If your symptoms are straightforward, a home test may still be a sensible first step.

How sleep apnoea severity is measured: AHI, oxygen levels and symptoms

Sleep apnoea severity is measured with more than one datapoint. Doctors combine the AHI, oxygen desaturation and symptom burden to understand risk and decide how urgently treatment should be discussed.

The apnoea-hypopnoea index, or AHI, estimates how many apnoeas and hypopnoeas occur per hour of sleep or recording time. In adults, common severity bands are:

• 5 to 14: mild

• 15 to 29: moderate

• 30 or more: severe

Oxygen desaturation also matters. Repeated or deeper drops in oxygen may make the case more clinically important, even when one summary number does not tell the whole story.

Symptoms matter too. A person with daytime sleepiness, morning headaches or safety concerns may need quicker treatment planning even if the AHI is not in the highest range.

This is why a sleep report should be interpreted by a doctor rather than read in isolation. Sleep apnoea diagnosis is a clinical decision built from test metrics plus real-world symptoms.

What your diagnosis may mean: mild, moderate and severe sleep apnoea

A mild, moderate or severe diagnosis helps guide treatment intensity, follow-up and urgency. It does not mean every person in the same AHI band will feel the same or need the same plan.

Mild sleep apnoea can still be important if you are very sleepy, have oxygen drops or have cardiovascular risks. Doctors may discuss lifestyle measures, positional strategies, ENT factors and sometimes CPAP.

Moderate sleep apnoea usually leads to a more active treatment conversation. Many patients in this group are considered for CPAP because symptom burden and physiological load are more likely to be meaningful.

Severe sleep apnoea generally warrants prompt review because the breathing disturbance is frequent. If significant oxygen desaturation, hypertension or atrial fibrillation is also present, treatment planning becomes more urgent.

Central sleep apnoea is different from obstructive sleep apnoea. If central events are suspected, the doctor may investigate medication effects, neurological causes or cardiac conditions before deciding on titration or device type.

Conditions linked with sleep apnoea that doctors also consider

Doctors assess sleep apnoea in context, not in isolation. Related conditions can increase suspicion, influence risk and affect which test or treatment pathway makes the most sense.

Common linked conditions include hypertension, obesity, atrial fibrillation and type 2 diabetes. These do not prove sleep apnoea, but they increase the importance of a proper sleep assessment.

Doctors also consider whether another sleep disorder may be present. Insomnia, parasomnias, restless legs symptoms or suspected narcolepsy may push the decision toward polysomnography instead of a simpler home test.

ENT issues can also matter. Persistent nasal blockage, enlarged tonsils or anatomical narrowing may affect both diagnosis and later treatment practicality, including mask tolerance and pressure comfort.

What happens after a diagnosis: treatment options and follow-up

After sleep apnoea diagnosis, treatment depends on the type of sleep apnoea, severity, symptoms and your doctor’s plan. CPAP is a common treatment for obstructive sleep apnoea, but it is not the only pathway.

CPAP works by delivering pressure that splints the airway open during sleep. Auto-adjusting devices such as ResMed AutoSet machines change pressure within a prescribed range, while humidification improves comfort for dryness and nasal irritation.

If CPAP is recommended, Comooz’s current bundle pricing is:

The ResMed AirSense 11 AutoSet has a full-colour touchscreen, Climate Control with integrated humidifier, over-the-air updates and Care Check-in. The ResMed AirSense 10 AutoSet uses a monochrome display with dial, integrated HumidAir chamber and built-in cellular connectivity for the myAir app.

Mask fit affects comfort and adherence. In general, nasal pillow masks suit people who want a minimal interface, while full face masks may suit mouth breathers or those with persistent nasal blockage.

Some patients need formal pressure titration. Others may need bilevel therapy, where inspiratory pressure and EPAP are set differently, especially if standard CPAP is not suitable. These decisions should be made with a doctor or sleep physician.

Sleep apnoea diagnosis costs in Singapore: what people should expect

Sleep apnoea diagnosis costs in Singapore vary by provider, setting and test type. The main cost difference is usually between a home sleep test and in-lab polysomnography, with more detailed studies typically involving more setup and coordination.

A Type 3 home sleep test is often the more accessible starting point when obstructive sleep apnoea is strongly suspected. A more detailed test such as polysomnography or manually arranged Type 2 testing may cost more because it involves broader monitoring and specialist workflow.

If treatment is recommended after diagnosis, machine pricing and trial policies also matter.

For current machine options after sleep apnoea diagnosis, see ResMed CPAP machines in Singapore.

Frequently asked questions

How is sleep apnoea diagnosed in Singapore?

Sleep apnoea is usually diagnosed by a doctor using your symptoms, medical history and a sleep study. This may be a home sleep test or in-lab polysomnography. The final interpretation considers breathing pauses, oxygen drops, AHI and your symptom burden rather than relying on snoring alone.

Can a home sleep test diagnose sleep apnoea accurately?

A home sleep test can help confirm suspected obstructive sleep apnoea in many adults, especially when symptoms and risk factors are clear. However, it may miss some cases or be less suitable if you have major heart, lung or neurological disease, suspected central sleep apnoea or another sleep disorder. A doctor should decide the right test.

What is the AHI and what numbers count as mild, moderate or severe?

AHI stands for apnoea-hypopnoea index, which estimates how many breathing interruptions happen per hour of sleep or recording time. In adults, doctors commonly classify 5 to 14 as mild, 15 to 29 as moderate and 30 or more as severe, while also considering oxygen levels, symptoms and overall clinical context.

Do I need to see a specialist if I snore loudly?

Not everyone who snores has sleep apnoea, but loud habitual snoring with choking, witnessed pauses, morning headaches or daytime sleepiness should be assessed. It is especially important to seek medical advice if you also have high blood pressure, obesity, diabetes, atrial fibrillation or excessive sleepiness affecting driving or work.

How much does it cost to get tested and treated after diagnosis?

Testing costs vary by provider and by whether you need a home sleep test, Type 2 study or in-lab polysomnography, so ask for an itemised quote. If CPAP is recommended after diagnosis, reference bundle pricing includes the AirSense 11 AutoSet Bundle at $2,068 nett and the AirSense 10 AutoSet Bundle at $1,868 nett, with separate trial and rental terms.

Can a smart watch or phone app diagnose sleep apnoea?

Consumer devices may flag snoring, restless sleep or possible oxygen changes, but they do not replace a medical sleep study. They can be useful prompts to seek assessment, but they cannot confirm or rule out sleep apnoea. If symptoms are concerning, speak to a doctor or sleep specialist for formal evaluation.
