CPAP vs BiPAP Machines: Types, Features, Uses & Differences
Sleep-related breathing problems can affect sleep quality, daytime energy and overall quality of life. CPAP and BiPAP machines, commonly known as PAP therapy devices, are used to support breathing during sleep and are prescribed for different patient needs.
But what is the difference between CPAP and BiPAP? What types of machines are available? And what should you know before choosing a machine?
Let's look at the basics.
What Is a CPAP Machine?
CPAP stands for Continuous Positive Airway Pressure.
A CPAP machine delivers positive airway pressure through a mask while you sleep. The pressure helps keep the upper airway open and is commonly prescribed for people with obstructive sleep apnea.
Modern CPAP machines may include features such as automatic pressure adjustment, humidification, data recording and comfort settings.
What Is a BiPAP Machine?
BiPAP stands for Bilevel Positive Airway Pressure.
Unlike basic CPAP therapy, BiPAP provides two pressure levels:
IPAP – Inspiratory Positive Airway Pressure
EPAP – Expiratory Positive Airway Pressure
The pressure used during inhalation can therefore be different from the pressure used during exhalation.
BiPAP may be prescribed for certain patients who require bilevel therapy based on their medical condition and clinician's assessment.
CPAP vs BiPAP
The basic difference is that CPAP generally provides one continuous pressure level, while BiPAP provides separate inspiratory and expiratory pressure levels.
However, choosing between CPAP and BiPAP should not simply be based on personal preference. A healthcare professional should determine which type of therapy is appropriate.
Popular ResMed Machines
There are many PAP machines available today. Some commonly recognized ResMed models include:
ResMed AirSense 10 – A widely used CPAP/Auto CPAP platform.
ResMed AirSense 11 – A newer generation Auto CPAP platform with modern features and a touchscreen interface.
ResMed Lumis 150 – A bilevel therapy platform designed for patients who require more advanced ventilatory support.
The exact model and configuration required depend on the patient's prescription and clinical needs.
What Should You Consider Before Buying a CPAP or BiPAP?
Before purchasing a machine, consider:
- Your prescribed therapy type
- Required pressure settings
- Mask compatibility
- Humidification requirements
- Data and monitoring features
- Availability of replacement parts
- Warranty and after-sales service
- Repair and maintenance support
- Availability of masks and accessories
Buying a machine is only one part of successful PAP therapy. Correct mask fitting, regular cleaning and proper maintenance are also important.

Final Thoughts
Understanding the differences between CPAP and BiPAP machines can make it easier to discuss your therapy options with your healthcare provider.
If you are using a PAP machine, don't change pressure or other prescribed therapy settings on your own. Always follow the recommendations of your doctor or qualified sleep/respiratory professional.
Better understanding can lead to better use of your prescribed therapy—and potentially better sleep.
