CPAP Machines—short for continuous positive airway pressure machines—are the most common and effective treatment for Obstructive Sleep Apnea (OSA). These devices deliver a steady stream of pressurized air through a mask, keeping your airway open so you can breathe normally throughout the night.

What is a CPAP Machine?
A CPAP machine is a medical device that treats obstructive sleep apnea by sending continuous pressurized air through a mask worn over the nose, mouth, or both. This airflow acts like a splint, preventing the airway from collapsing during sleep. As a result, CPAP therapy improves oxygen levels, reduces snoring, prevents apnea events, and enhances overall sleep quality.
Because CPAP machines are regulated medical devices, most require a prescription after a sleep study determines your breathing patterns and pressure needs.
How CPAP Machines Work
CPAP therapy uses consistent air pressure to:
- Keep the airway open
- Prevent breathing pauses
- Support normal airflow
- Reduce nighttime awakenings
- Improve daytime alertness
Modern CPAP machines are quiet and come with features like:
- Heated humidifiers (much needed for Canadian climates)
- Mask-fit check tools
- Auto-adjusting pressure
- Wireless data tracking
These enhancements improve comfort, accuracy and long-term adherence to therapy.
Types of CPAP Machines
- Standard (Fixed Pressure) CPAP: delivers one constant air pressure throughout the night.
- Auto-Adjusting CPAP (APAP): adapts pressure automatically depending on sleep stage, position, and breathing changes.
- BiLevel Machines (BiPAP): provides higher pressure on inhalation and lower pressure on exhalation. BiPAP is ideal for individuals with Central Sleep Apnea or difficulty exhaling against continuous pressure.
- Travel CPAP Machines: compact, ultra light options designed for portability and frequent travel.
Key Components of a CPAP Machine
A CPAP consists of:
- Motor: Generates air pressure
- Humidifier: Adds moisture to prevent dryness
- Tubing: Connects the machine to the mask
- Mask: Ensures a sealed air path
- Filter: Cleans the incoming air
- Headgear: Holds the mask securely in place
Each component plays a critical role in comfort and performance, and routine replacement is essential for safe and effective sleep therapy.
Filters are important as its job is to purify the air by blocking dust, pollen, allergens and debris from entering your airway and machine. Dirty filters can cause congestion, dryness, and poor machine performance.
Benefits of CPAP Therapy
CPAP therapy can:
- Eliminate or reduce snoring
- Improve oxygen intake
- Restore normal sleep cycles
- Reduce morning headaches
- Boost daytime alertness
- Lower the risk of heart disease and stroke
- Improve overall long-term health
Consistency is key for full therapeutic benefit.
Common Side Effects and How to Fix Them
Some users experience:
- Dry mouth
- Nasal congestion
- Mask discomfort
- Skin irritation
- Air leaks
Solutions include:
- Heated humidification
- Mask fit adjustments
- Switching mask styles
- Replacing worn parts
- Gradual acclimation
Tips for Comfortable CPAP Use
- Choose a mask style that matches your breathing habits
- Use a ramp feature to ease into pressure
- Clean and replace parts regularly
- Try mask liners for reduced irritation
- Wear the mask during the day briefly to acclimate
- Keep a consistent nightly routine
Troubleshooting Common CPAP Issues
If you're experiencing leaks, noise or discomfort:
- Tighten or refit the mask
- Replace cushions or headgear
- Check tubing for cracks
- Adjust humidity settings
- Consult your sleep clinic or provider
How to Choose the Right CPAP Machine
Consider:
- Your type of sleep apnea (OSA, CSA, Complex)
- Pressure Needs
- Mask compatibility
- Noise level
- Humidification options
- Data-tracking features
- Travel needs
- Budget and insurance coverage
Some brands also offer ultra-compact travel models for convenience.
