Updated June 2026 12 min read Sleep Apnoea Treatment
If you've recently been diagnosed with sleep apnoea, your healthcare provider has likely recommended CPAP therapy. For many beginners, starting treatment can feel overwhelming — there are machines, masks, hoses, cushions, settings, and replacement schedules to learn about.
The good news? Millions of people successfully use CPAP therapy every night and enjoy better sleep, improved energy, and healthier lives. This guide covers everything you need to know to get started with confidence.
Understanding CPAP
What is CPAP therapy?
CPAP stands for Continuous Positive Airway Pressure. It's one of the most effective treatments for sleep apnoea available today.
A CPAP machine delivers a gentle stream of air through a mask while you sleep. This airflow keeps your airway open and helps prevent breathing interruptions caused by obstructive sleep apnoea (OSA).
Without treatment, sleep apnoea can contribute to:
🔊
Loud snoring
Disrupts sleep for you and your partner
😴
Excessive daytime fatigue
Constant tiredness and low energy levels
🧠
Poor concentration
Difficulty focusing at work or in daily activities
🤕
Morning headaches
Waking up with persistent head pain
❤️
High blood pressure
Increased cardiovascular strain and risk
The Mechanism
How CPAP therapy works
Understanding the process helps you see why consistency matters.
When you sleep, the muscles in your throat naturally relax. For people with sleep apnoea, this relaxation can cause the airway to partially or completely collapse, creating repeated pauses in breathing.
A CPAP machine prevents this by providing constant air pressure that keeps your airway open throughout the night. This helps:
✓
Reduce snoring
Open airways eliminate the vibrations that cause snoring sounds.
✓
Improve oxygen levels
Consistent airflow ensures your brain and body get adequate oxygen overnight.
✓
Promote deeper sleep
Without breathing interruptions, you stay in deeper sleep stages longer.
✓
Improve daytime alertness
Better sleep quality leads to more energy and focus during the day.
Getting Started
Essential CPAP equipment you'll need
Here's what comes with your therapy setup — and what matters most.
1. The CPAP Machine
The machine generates and delivers pressurised air. Three main types exist:
⚙️
Fixed Pressure CPAP
Delivers one consistent pressure level throughout the night
🔄
Auto CPAP (APAP)
Automatically adjusts pressure based on breathing patterns
↔️
BiLevel (BiPAP)
Provides different pressures for inhalation and exhalation
Your healthcare provider will recommend the best option based on your needs.
2. The CPAP Mask
The mask is often the most important factor in therapy success. A comfortable mask makes the difference between treatment success and frustration. Three main styles exist:
😷
Full Face Masks
Cover both nose and mouth. Best for mouth breathers, higher pressure settings, and those with nasal congestion. Popular choice: ResMed AirFit F20.
👃
Nasal Masks
Cover only the nose. Best for side sleepers and those who primarily breathe through their nose.
💨
Nasal Pillow Masks
Sit directly under the nostrils. Best for minimal contact, active sleepers, and those who dislike larger masks.
3. Tubing
CPAP tubing connects your machine to the mask and delivers airflow throughout the night. Standard diameter tubing fits most machines.
4. Humidifier
Many modern CPAP machines include heated humidification. A humidifier can help reduce dry mouth, nasal dryness, and throat irritation — all common early adjustments.
Critical Decision
Choosing the right CPAP mask
Finding the right mask is often the biggest factor in long-term CPAP success.
Look for these key features:
✓
Comfortable cushion material
✓
Easy cleaning and maintenance
