Understanding APAP Machines: How They Differ from CPAP and What’s Best for You
For people living with sleep apnea, choosing the right therapy device is one of the most important steps toward better sleep and long-term health. You’ve likely come across terms like CPAP and APAP — but what do they mean, and how do you know which one is right for you?
On this page, we’ll walk you through what APAP machines are, how they differ from standard CPAP machines, and why the choice between them can make a difference in your comfort and therapy outcomes. We’ll also share real-world usage tips and explain how Sove CPAP Clinic helps patients through every step — from diagnosis and setup to ongoing support.
An APAP Machine Automatically Adjusts Air Pressure
APAP stands for Auto-Adjusting Positive Airway Pressure. Unlike standard CPAP machines that deliver a fixed level of air pressure all night, APAP machines use smart technology to monitor your breathing in real time. They adjust the pressure level on a breath-by-breath basis to suit your needs.
This is particularly helpful because your breathing patterns can change throughout the night — depending on your sleep stage, body position, and nasal congestion. For example, you might need a higher pressure while sleeping on your back, or during REM sleep when apnea events are more likely. An APAP machine detects subtle changes in airflow and automatically raises or lowers the pressure to keep your airway open.
Devices like the ResMed AirSense 11AutoSet or the Fisher &Paykel SleepStyle+ Auto are popular. These models continuously respond to your breathing and are designed to provide the minimum effective pressure, reducing the chance of discomfort or unnecessary pressure spikes.
APAP machines are ideal for patients with variable pressure needs or for those undergoing an initial trial to determine optimal therapy settings. Sove CPAP Clinic offers expert consultations and support in choosing, configuring, and using APAP devices effectively.
A CPAP Machine Delivers a Constant, Fixed Air Pressure
While APAP machines auto-adjust, CPAP (Continuous Positive Airway Pressure) machines are set to deliver one specific pressure level throughout the night. This pressure is usually determined after a sleep study and titration process, either in a sleep lab or using an auto-adjusting machine for data collection.
Some patients respond very well to fixed pressure therapy. If your ideal pressure is consistent and your apnea is well-controlled, a CPAP machine may be the simplest, most effective option. Fixed-pressure therapy can also be beneficial for people who prefer predictable settings or are sensitive to fluctuations in airflow.
Machines like the ResMed AirSense 10 Elite provide this stable support. They’re often slightly more affordable and easier to operate for those who don’t need constant adjustment.
Sove CPAP Clinic helps patients transition between machine types as their therapy progresses. If you’ve started on an APAP and find that your pressure needs are stable, we can help you switch to a fixed CPAP — with clinician support and therapy reviews.
APAP and CPAP Machines Are Used to Treat Sleep Apnea and Snoring
Both APAP and CPAP machines are effective treatments for obstructive sleep apnea and can significantly improve quality of life. They work by delivering pressurised air that keeps your upper airway open while you sleep, preventing the collapse that causes breathing pauses, snoring, and oxygen drops.
Over time, consistent therapy with either machine type can help:
- Lower your Apnea-Hypopnea Index (AHI)
- Reduce or eliminate loud snoring
- Improve energy and alertness during the day
Your sleep physician or clinician will typically recommend a machine based on the results of a diagnostic sleep study. These studies can be conducted in-clinic or at home using modern home sleep testing kits.
Not sure which type of machine you need? Start with a home sleep study from Sove CPAP Clinic. We’ll analyse your sleep data and recommend the best solution tailored to your breathing patterns and lifestyle. To access a bulk billed sleep study through Sove CPAP Clinic, you’ll first need a referral from a medical doctor.

Frequently Asked Questions
Do I need a sleep study before using an APAP or CPAP machine?
Yes, a sleep study is essential to determine whether you have sleep apnea and how severe it is. This diagnosis informs your treatment plan and helps clinicians decide whether an APAP or CPAP machine is more suitable for you.
Sove CPAP Clinic offers both in-lab sleep studies and convenient home sleep study kits. These tests measure your breathing patterns, oxygen levels, and sleep disruptions. Once your data is reviewed, your clinician can recommend a therapy option and pressure settings tailored to your needs.
Using a CPAP or APAP machine without proper diagnosis and guidance can result in ineffective treatment. It’s always best to start with a comprehensive assessment.
Sove Tip: Book a home sleep study with Sove CPAP Clinic for a fast and easy way to start your treatment journey from the comfort of your own bed.
Is an APAP or CPAP machine covered by private health insurance?
In many cases, yes — private health insurance with extras cover may provide a rebate for CPAP or APAP machines, masks, and accessories. The amount depends on your fund, your level of cover, and whether you’ve served any waiting periods.
It’s a good idea to contact your health fund directly to ask about coverage for sleep apnea equipment. Most funds require a medical diagnosis and may ask for a quote or clinical recommendation.
Sove CPAP Clinic provides quotes, itemised receipts, and support letters to assist with claims. We’re happy to help you navigate your insurance process and maximise your entitlements.
Is there a trial or return policy for APAP and CPAP machines at Sove CPAP Clinic?
Yes, we offer a CPAP trial program so you can experience therapy before committing to a specific machine or mask. The program includes:
- A set trial period (usually 4 weeks)
- Machine setup and education
- Mask fittings and adjustments
- Ongoing support and pressure reviews
At the end of your trial, we review your data and comfort levels to help you choose the best long-term device. This reduces the risk of buying a machine that doesn’t suit your needs.
Ask about our trial packages, which include access to multiple mask types and brands so you can find the perfect fit before purchase.
Can I switch from an APAP to a CPAP machine if my pressure doesn’t need to change?
Yes, this is quite common. Some patients start with an APAP machine to gather detailed data over time. If the data shows your required pressure is stable throughout the night, your clinician may recommend switching to a fixed-pressure CPAP for simplicity.
This switch can make therapy more affordable and easier to manage. It’s important to do this under the guidance of a sleep professional to ensure continued effectiveness.
Sove CPAP Clinic reviews your therapy data and works with you and your doctor to decide if a machine switch is appropriate. We’ll help adjust your equipment and settings to match your ongoing needs.
Are the APAP and CPAP mask attachments and accessories the same?
Yes, in most cases, the masks, tubing, humidifiers, and filters are interchangeable between APAP and CPAP machines — especially if they’re from the same brand. Standard universal connections make it easier to upgrade or change your device without replacing all your accessories.
However, some machines have brand-specific components, so it’s always best to double-check compatibility before purchasing new parts.
Our team can help you choose the right accessories for your machine and ensure everything works together smoothly. We stock a wide range of parts and replacements for most major brands.
Does Sove CPAP Clinic offer support for APAP and CPAP troubleshooting?
Absolutely. Our support doesn’t stop when you leave the clinic. We offer:
- Telehealth consultations for therapy questions, comfort issues, or equipment problems
- In-clinic reviews to check pressure settings and machine performance
- Equipment servicing and cleaning advice
Whether you’re experiencing mask leaks, discomfort, or technical issues, our experienced team is just a call or visit away.
