Limited time: $150 off selected CPAP machines

    Published 21 August 2026 · Comooz clinical team, Singapore

    Quick answer

    An automatic CPAP machine, also called APAP, adjusts pressure within a prescribed range during sleep to treat confirmed obstructive sleep apnoea more flexibly than fixed-pressure CPAP. In Singapore, the best buying path is diagnosis first, then mask fit, humidification, follow-up support, and current bundle pricing such as ResMed AirSense 11 AutoSet at $2,068 nett and AirSense 10 AutoSet at $1,868 nett.

    What is an automatic CPAP machine?

    An automatic CPAP machine is a PAP device that adjusts pressure within a clinician-set range as breathing changes through the night. It is commonly called APAP, and it is usually considered after a doctor or sleep physician confirms obstructive sleep apnoea (OSA) and recommends PAP therapy.

    OSA happens when the upper airway narrows or collapses during sleep. This can cause snoring, oxygen desaturation, repeated brain arousals, and symptoms such as daytime sleepiness, unrefreshing sleep, morning headache, and poor concentration.

    Collapsed airway during obstructive sleep apnea

    A simple definition is this: an automatic CPAP machine does not diagnose or manage OSA, but it delivers positive airway pressure that helps splint the airway open while the therapy is being used. A sleep study may be a lab polysomnography test or a home sleep test, including Type 2 or Type 3, depending on the case.

    How CPAP pressure splints the airway open

    If you are comparing devices after diagnosis, see Comooz’s current CPAP machines in Singapore.

    How an automatic CPAP machine works during sleep

    An automatic CPAP machine analyses breathing signals and adjusts pressure within a prescribed minimum-to-maximum range. The goal is to provide enough pressure to reduce obstructive events without staying unnecessarily high all night.

    In practice, the device responds to patterns such as snoring, flow limitation, and obstructive breathing changes. Pressure needs may rise when a person sleeps on the back, enters REM sleep, or has nasal congestion, then fall again later.

    This is why APAP can feel more comfortable for some users than fixed-pressure CPAP. It still requires proper setup, and treatment decisions should be reviewed by a doctor or sleep physician rather than made from machine data alone.

    Automatic CPAP vs fixed-pressure CPAP: key differences

    An automatic CPAP machine and a fixed-pressure CPAP both treat OSA with positive airway pressure, but they deliver that pressure differently. The right choice depends on the sleep study, titration result, symptoms, comfort, and clinician advice.

    FeatureAutomatic CPAP machine (APAP)Fixed-pressure CPAP
    Pressure deliveryAdjusts within a prescribed range during sleepDelivers one set pressure all night
    ComfortMay feel easier for some users because pressure can stay lower when less support is neededCan work very well when one pressure is clearly effective and tolerated
    ResponsivenessResponds to airflow changes, snoring, flow limitation, and obstructive patternsDoes not automatically change pressure during the night
    Best fitUsers whose pressure needs vary by sleep stage, body position, or nasal blockageUsers with stable pressure needs after titration
    Follow-up dataOften used with AutoSet-style event and leak trackingAlso records therapy data, but without auto-adjusting pressure
    Clinical cautionNot a substitute for diagnosis; not suitable for every breathing disorderAlso requires correct prescription and setup

    If a patient needs a different pressure relationship between inhalation and exhalation, a clinician may consider bilevel therapy instead. In bilevel treatment, settings such as EPAP and pressure support become more important than standard APAP behaviour.

    Who may benefit from an automatic CPAP machine

    An automatic CPAP machine may suit people whose pressure requirements change during the night. It is usually discussed for confirmed obstructive sleep apnoea, not for self-treating snoring without testing.

    You may be a reasonable APAP candidate if you have:

    • Confirmed obstructive sleep apnoea
    • Symptoms such as snoring, witnessed pauses, daytime sleepiness, or morning headache
    • Pressure needs that vary with position, REM sleep, or congestion
    • A clinician recommendation after a sleep study, follow-up review, or titration

    A useful measure here is AHI, the apnea-hypopnea index. AHI is the number of apneas and hypopneas per hour of sleep, and it helps classify severity.

    Apnea-hypopnea index severity scale

    AHI levelSeverity
    5-14.9Mild OSA
    15-29.9Moderate OSA
    30 or moreSevere OSA

    Who this is for and not for

    This guide is for adults in Singapore comparing APAP purchase, trial, or rental after suspected or confirmed OSA. It is not for self-diagnosing sleep apnoea, managing suspected central apnoea, or replacing medical review when symptoms are complex.

    What to check before buying an automatic CPAP machine in Singapore

    Before buying an automatic CPAP machine in Singapore, confirm the diagnosis, machine type, bundle contents, and support after setup. The safest purchase follows a proper clinical pathway rather than a snoring-only assumption.

    Confirm the diagnosis first

    A doctor consultation should come before machine selection. OSA is usually confirmed with polysomnography or a home sleep test.

    Comooz provides information on home sleep test options in Singapore. Comooz states that Type 3 home sleep tests are available on demand, while Type 2 tests are arranged manually with a trained specialist.

    Know whether you need APAP, fixed CPAP, or bilevel

    Machine choice should follow the sleep report and clinical recommendation. Some users do well on AutoSet therapy, while others need fixed CPAP or bilevel support where EPAP and pressure support are part of the prescription.

    Review the pressure plan and titration pathway

    Ask whether setup will use a prescribed pressure range or a single fixed pressure. Also ask whether the plan came from formal titration, physician review, or a guided PAP setup based on your sleep test.

    Check humidification and comfort features

    Built-in humidification matters because dryness, congestion, and nasal irritation can reduce adherence. This is especially relevant for users sleeping in air-conditioned rooms in Singapore.

    Ask what support is included

    Mask fitting, troubleshooting, setup guidance, and follow-up help matter as much as the machine itself. Comooz, a Singapore CPAP provider (UEN 201808754M), positions support as part of the PAP pathway rather than just a box sale.

    Diagnosis and setup: what should happen before you start

    Before starting an automatic CPAP machine, a doctor or sleep specialist should confirm whether OSA is present and whether PAP therapy is appropriate. The aim is to match treatment to the breathing disorder, not just to buy a machine quickly.

    A typical pathway may include:

    1. Symptom review, such as snoring, witnessed pauses, daytime sleepiness, or morning headache.

    2. A sleep assessment with polysomnography or a home sleep test.

    3. Review of AHI, oxygen desaturation patterns, event types, and sleep history.

    4. Recommendation for APAP, fixed-pressure CPAP, or another therapy.

    5. Setup of the pressure range, mask, humidifier, and follow-up plan.

    If there are concerns about central events, poor PAP tolerance, or more complex respiratory issues, machine choice may need closer physician review. That is one reason diagnosis-first buying is safer than choosing based on online price alone.

    Masks, comfort and adherence: what affects success

    Mask fit is one of the biggest predictors of success with an automatic CPAP machine. A good machine can still fail in practice if the mask leaks, feels claustrophobic, or does not match the user’s breathing pattern.

    There are three common mask categories:

    Mask typeCommon use caseExamples discussed here
    Nasal pillowsMinimal-contact option for users who prefer a light feelResMed AirFit P10, AirFit P30i
    Nasal mask / cradleGood for many nose-breathers who want stability with less facial coverageResMed AirFit N20, AirFit N30, AirFit N30i
    Full face maskOften considered for mouth breathing, congestion, or when a nasal mask is unsuitableResMed AirFit F20, AirTouch F20, AirFit F30i

    ResMed AirFit P30i nasal pillows CPAP mask with top-of-head tube

    A nasal pillow vs full face decision usually depends on whether you mainly breathe through your nose, whether you have persistent congestion, and how much facial coverage you can tolerate. A fitted mask matters more than category labels alone.

    Mask styleUsually a better fit forTrade-off to consider
    Nasal pillowsUsers who want minimal facial contact and mainly nose-breatheCan be harder if nasal dryness or blockage is significant
    Nasal cradle / nasal maskUsers who want a balance of comfort and stabilityStill relies on reasonably good nasal breathing
    Full faceUsers with frequent mouth breathing or persistent congestionMore facial coverage and potentially more contact points

    Nose versus mouth breathing during sleep

    People who mainly nose-breathe often prefer lighter masks such as nasal pillows or nasal cradle styles. People with regular mouth breathing may need a full face option, though a proper fitting is still essential.

    Humidification also affects adherence. Dryness, congestion, air leaks, and skin irritation can all reduce nightly use, so small setup changes can make a large practical difference.

    Which mask style is usually the best starting point?

    For many adults with confirmed OSA who mostly breathe through the nose, a nasal interface is often the simplest starting point. For users with frequent mouth breathing, persistent nasal blockage, or poor seal on nasal options, a full face mask may be more practical.

    Key takeaways before choosing an automatic CPAP machine

    An automatic CPAP machine is usually best chosen after proper sleep evaluation, not from snoring alone. The right setup depends on diagnosis, pressure range, mask fit, humidification, and support after you start.

    For most buyers in Singapore, the practical checklist is simple: confirm OSA with a doctor or sleep physician, compare automatic CPAP machine options against fixed CPAP, understand bundle pricing, check what the trial or rental terms actually include, and make sure the mask has been properly fitted.

    Frequently asked questions

    What is the difference between an automatic CPAP machine and a regular CPAP machine?

    An automatic CPAP machine, or APAP, adjusts pressure within a prescribed range based on breathing changes during sleep. A fixed-pressure CPAP delivers one set pressure all night. APAP may feel more comfortable for some users, but the best option depends on the sleep study, titration approach, symptoms, and a doctor’s recommendation.

    How much does an automatic CPAP machine cost in Singapore?

    At Comooz, the ResMed AirSense 11 AutoSet Bundle is $2,068 nett and the AirSense 10 AutoSet Bundle is $1,868 nett. A 5-night CPAP trial is not free and includes a deposit, mask cost, and $98 return fee. Monthly rental is also available with 3-month offset rules toward purchase.

    Do I need a sleep test before buying an automatic CPAP machine?

    You should not self-diagnose sleep apnoea based only on snoring or tiredness. A doctor or sleep specialist will usually recommend a sleep assessment, such as polysomnography or a home sleep test, to confirm OSA, review AHI and event type, and decide whether PAP therapy is appropriate.

    Is an automatic CPAP machine safe to use every night?

    CPAP therapy is widely used and generally safe when prescribed and set up properly, but it remains a medical treatment. Common issues include dryness, mask leaks, aerophagia, skin irritation, and discomfort. If you have persistent symptoms, central apnoea concerns, lung disease, or poor tolerance, follow up with your doctor promptly.

    Can I rent or try an automatic CPAP machine before buying?

    Yes, some patients prefer a supervised trial or rental before purchase. At Comooz, the 5-night CPAP trial includes a deposit, mask cost, and $98 return fee, and monthly rental is available with 3-month offset rules toward purchase. Always confirm what is refundable and what counts toward a later purchase.

    Which masks work best with an automatic CPAP machine?

    There is no single best mask for everyone. Nasal pillows, nasal masks, and full face masks suit different sleeping habits, facial structures, and breathing patterns. The most important factors are seal, comfort, and consistent use. If you breathe through your mouth or have congestion, ask your clinician which style may be more suitable.
