APAP vs. CPAP And BiPAP: What’s The Difference?

A poorly fitting mask, a bad night’s sleep, or a change in your sleep pattern may lead to sleep apnea. A sleep apnea dentist can help you get the diagnosis and treatment that you need to get the best sleep possible. A pillow mask might be a good option for people with allergies, skin irritations, or breathing problems. A CPAP machine is a common option to help people breathe at night while they sleep. BiPAP machines are typically carried out when someone has both an apnea problem and heart disease. APAP stands for auto-PAP, a machine used to help people breathe by changing the pressure of the air in their lungs. Sleep apnea can be a treatable disease and can cause you to feel tired during the day. Learning about sleep apnea is important for both you and your dentist.

APAP- Automatic Positive Airway Pressure

APAP machine is a breathing machine that your physician prescribes to treat sleep apnea. APAP machines typically have three different pressures that can be adjusted on the machine. The first pressure setting is a positive pressure, which keeps the airways open and prevents muscle collapse during sleep. The second pressure setting is usually a negative pressure, which helps simulate normal breathing during sleep. The third pressure setting is a positive pressure that helps relax the airways and prevent muscle collapse.

CPAP- Continuous Positive Airway Pressure

CPAP machine is a breathing machine that your physician prescribes to treat sleep apnea. CPAP machines have one pressure setting. The pressure is set at a constant positive level and increases gradually during sleep. They are typically used to treat mild to moderate obstructive sleep apnea and snoring. Moreover, CPAP machines are used to treat both obstructive and central sleep apnea. APAP machines can be combined with CPAP machines to increase treatment options and improve effectiveness.

BiPAP- Bilevel Positive Airway Pressure

BiPAP machines are breathing machines that your physician prescribes to treat sleep apnea and heart disease. BiPAP machines can treat both apnea and heart disease. There are two different pressure settings for each exhalation and inhalation. During the exhalation, the airway pressure is set at a low level to help decrease resistance in the airways, while turning up the pressure to a high level during inhalation to help open the airways.

APAP vs. CPAP and BiPAP: What’s the difference?


The APAP machine works by directing air pressure at the back of the throat and soft palate to help open a blocked airway. The airways are then free from obstruction so that breathing is not obstructed during sleep.

The CPAP machine helps create a controlled airflow through the nose, mouth, and throat to keep your lungs open to breathe and maintain healthy oxygen levels throughout your body.

The BiPAP machine is actually a mixture of CPAP and APAP machines. It can be a machine that provides both CPAP and APAP, or it can be used to treat heart failure or sleep apnea.


Both APAP machines and CPAP machines are used in the treatment of sleep apnea.

The BiPAP machine is usually prescribed when someone has both sleep apnea and heart failure. It is applied when a person can use the good effects of both the APAP and CPAP machines.

Special Considerations

While some people find comfort from using a CPAP machine, others need to use an APAP or BiPAP machine instead. It is important to find the right machine that suits your needs and helps treat sleep apnea.

How Sleep Apnea Affects Your Life

Sleep apnea is a treatable condition that can negatively affect your quality of life. You might feel tired during the day and often have trouble concentrating. You could have car accidents due to lack of sleep, you may forget things, or even suffer from mood swings. If you are diagnosed with sleep apnea, your dentist can recommend a CPAP machine or a BiPAP machine to help you breathe better while you sleep. You may be able to get the treatment you need at a sleep studies center. You should be able to ask your dentist if they work with the specialists at a sleep study center.


There are several different options to help treat sleep apnea, including CPAP machines and BiPAP machines. Learning about the effects of different types of treatment can help you get the right diagnosis and treatment that is right for you. Moreover, it will help your dentist make sure the treatment will be effective for your needs.
