What Does a CPAP Machine Do?
If you’ve been diagnosed with sleep apnea or are curious about CPAP therapy, you might be wondering: What does a CPAP machine actually do? At its core, a CPAP (Continuous Positive Airway Pressure) machine is a simple yet life-changing device designed to help you breathe more freely during sleep. It keeps your airway open, reduces sleep disruptions, and helps you wake up feeling refreshed and energised.
In this comprehensive guide, we’ll unpack exactly how a CPAP machine works, its key components, and why it’s such an essential part of sleep apnea therapy. We’ll also explore comfort features, compliance tips, and answer some of the most common questions our patients ask at Sove CPAP Clinic. Whether you’re new to therapy or looking to fine-tune your experience, we’re here to help you get the most out of every night’s sleep.
The Basics: How Does a CPAP Machine Help?
A CPAP machine delivers a constant stream of pressurised air through a mask to keep your upper airway open while you sleep. When you sleep, the muscles in your throat naturally relax. For people with obstructive sleep apnea (OSA), these relaxed muscles can collapse inward, blocking the airway and stopping airflow. This leads to apnea events—pauses in breathing—that can happen dozens or even hundreds of times per night.
A CPAP machine prevents this collapse by gently pushing air into your throat. Think of it as an “air splint” that props the airway open. This constant airflow stops the tissues from collapsing, allowing you to breathe normally throughout the night.
Real-world benefit: With CPAP therapy, you’ll likely experience fewer awakenings, reduced snoring, and improved blood oxygen levels—key for feeling rested and alert during the day.
Core Components of a CPAP Machine
A CPAP machine may look simple, but it’s a carefully designed system made up of several interconnected parts:
Main Unit (Airflow Generator): This is the heart of the machine, containing a quiet motor that generates pressurised air. Modern devices, like the ResMed AirSense 10 or Philips DreamStation, are compact, lightweight, and whisper-quiet.
Air Filter: Removes dust, allergens, and particles from the air before it reaches your airway. Regular filter replacement ensures clean, safe therapy.
Humidifier: Optional but highly recommended, a humidifier adds moisture to the airflow, helping prevent dry nose, mouth, and throat. Many modern models feature integrated heated humidifiers for maximum comfort.
Tubing: A flexible hose that carries the pressurised air from the machine to your mask. Heated tubing options can prevent condensation (known as “rainout”).
Mask: The interface that delivers air to your airway. Options include nasal masks (covering just the nose), nasal pillow masks (resting at the nostrils), and full-face masks (covering nose and mouth).
Each component plays a crucial role in effective therapy. At Sove CPAP Clinic, we help patients select, fit, and maintain these parts to ensure the best possible experience.
How the CPAP Machine Knows When to Work
Modern CPAP machines use smart sensors to detect your breathing patterns. When you put on your mask and start to breathe, the machine senses the airflow and pressure changes. This triggers the machine to deliver the prescribed pressure.
Some advanced models, like the ResMed AirSense 11 AutoSet or Philips DreamStation Auto, are auto-adjusting (APAP) devices. They can automatically increase or decrease pressure in response to your needs throughout the night. For example, if your airway starts to narrow, the machine will increase pressure to keep it open. If your breathing is stable, it might decrease pressure slightly to maximise comfort.
This technology means the machine adapts to your sleep stages, position, and even nasal congestion—helping maintain effective therapy all night.

Comfort Features that Make a Difference
Early CPAP machines were noisy and basic, but today’s devices are packed with features designed to make therapy as comfortable as possible. Here are some of the most popular features and how they help:
Ramp Function: Starts at a lower pressure and gradually increases to your prescribed level, making it easier to fall asleep.
Expiratory Pressure Relief (EPR or Flex): Eases the pressure when you breathe out, making exhalation more comfortable.
Heated Humidifier: Adds warmth and moisture to prevent dryness and irritation.
Heated Tubing: Maintains air temperature, reducing condensation in the hose.
Quiet Operation: Most modern CPAPs are extremely quiet—ideal for both you and your bed partner.
Data Tracking and Apps: Machines like the AirSense 10 with myAir or DreamStation with DreamMapper provide detailed sleep reports, helping you track progress and compliance.
Tip: At Sove CPAP Clinic, we often help patients adjust these features for maximum comfort—sometimes a small tweak to the humidifier or EPR settings can make a world of difference.
CPAP and Therapy Compliance: Why Consistency Matters
Using your CPAP machine every night is essential for effective therapy. Skipping nights can lead to a return of symptoms, fragmented sleep, and health risks like high blood pressure, heart disease, and daytime sleepiness.
Sticking with therapy every night—even during naps—helps train your body to adapt to the therapy. Most users find that, after an initial adjustment period, they can’t imagine sleeping without it.
Real-world tip: If you’re having trouble adjusting, try wearing your mask while reading or watching TV to get used to the feeling. And if you’re still struggling, book a follow-up appointment with Sove CPAP Clinic. We can help troubleshoot and make adjustments that make therapy easier to stick with.

Common Questions About CPAP Machines
What Does a CPAP Machine Actually Do?
A CPAP machine delivers a steady stream of pressurised air through a mask to keep your airway open while you sleep. This prevents airway collapse and helps you maintain normal breathing patterns throughout the night. By reducing or eliminating apnea events, it not only improves your oxygen levels but also promotes deeper, more restorative sleep. Over time, this can reduce daytime sleepiness, improve focus, and support better overall health.
How Does a CPAP Machine Know When I’m Asleep?
CPAP machines can’t directly detect sleep stages like a sleep lab EEG, but they use sophisticated sensors to monitor your breathing. These sensors detect changes in airflow and breathing patterns. For example, during sleep, your breathing typically becomes more regular and slower. The machine uses this information to maintain optimal therapy. Auto-adjusting models can even respond in real-time, increasing or decreasing pressure based on your needs, which helps keep your therapy comfortable and effective all night.
Can a CPAP Machine Tell If I Stop Breathing?
Yes, modern CPAP machines are equipped with technology that senses pauses in breathing (apneas) or partial blockages (hypopneas). They monitor airflow resistance and patterns to detect when you’re not breathing effectively. When an event occurs, auto-adjusting machines can automatically raise the pressure to reopen the airway. In addition, the machine logs these events, providing valuable data for you and your healthcare team to assess the therapy’s effectiveness and make adjustments if needed.
What If I Feel Claustrophobic Wearing a Mask?
It’s common to feel a bit claustrophobic when first starting CPAP therapy. The sensation of wearing a mask can take some getting used to. Start by wearing the mask during the day while reading or watching TV to acclimate yourself to the feeling. Choosing the right mask type—such as a nasal pillows mask that sits at the nostrils instead of covering the entire nose or mouth—can also help. At Sove CPAP Clinic, we specialise in mask fittings and can guide you through selecting the most comfortable option for your needs. Remember, adjusting to CPAP is a journey, and our team is here to support you every step of the way.
How Do I Keep My CPAP Machine Clean?
Keeping your CPAP machine and accessories clean is essential for maintaining therapy effectiveness and hygiene. Wash the mask, tubing, and humidifier chamber at least weekly using warm water and mild soap. Rinse thoroughly and let them air dry completely before reassembly. The air filter should be checked regularly and replaced as recommended by the manufacturer. Sove CPAP Clinic offers maintenance tips, replacement parts, and cleaning guidance to make sure your equipment stays in top condition. Regular cleaning not only prolongs the life of your machine but also helps prevent infections and ensures you’re getting the best therapy every night.
