What are the differences between BIPAP and CPAP devices?

Have you been diagnosed with sleep apnea? Then BIPAP or CPAP these terms are very familiar for you. BIPAP refers to the Bilevel positive airway pressure, while CPAP refers to the Continuous Positive Airway Pressure.

Hence knowing about the difference between these two types of therapy is very important if you want to ensure that you are receiving the proper level of treatment through your device. However, which one works better for you? Hence, we are here to discuss the BIPAP devices and CPAP devices so that you can have a clear idea about which one to use. Have a look:

What is BIPAP therapy?

BIPAP or the BPAP devices are known to deliver the Bilevel Positive Airway Pressure. This machine comes with a very similar function to CPAP therapy. However, there are some striking differences. BIPAP and CPAP machines are quite similar in design and function, which makes them a compatible component for the non-invasive form of therapy for sleep apnea patients. Similar to CPAP treatments, the BPAP treatment keeps the airways from collapsing and allows the users to have very easy breathing during sleep.

What makes the BIPAP and CPAP devices different from each other?

Though the BIPAP and CPAP devices are quite similar in functionality, it comes with a variety of differences which makes each of the therapies and devices distinct in trait. Here are the differences:

  • BIPAP machines come with the two-pressure setting:

The primary difference between the BIPAP and CPAP devices is, the BIPAP comes with two pressure settings. Usually, it includes two parts for the settings. One part of the pressure is for inhalation, which is known as IPAP, and the lower pressure comes for exhalation, which is known as EPAP.

The BIPAP machines come with a design that increases the pressure when you inhale to prevent the airways in your nose and throat from closing while you are sleeping. Also, it provides a very lower pressure during the exhalation, which is great for maintaining an open airway. Hence most of the patients prefer BIPAP more comfortably than the single pressure delivery of the CPAP devices.

On the other hand, the CPAP devices come with a singular pressure setting, which oftentimes causes some irritation with breathing. Exhaling becomes much more challenging for the patients who use the CPAP devices with higher pressure settings.

  • BIPAP machines and CPAP machines work to serve different needs:
  • People who have problems with their nerves and muscles seek to benefit from the BIPAP machines. BIPAP machines are easy to set to ensure that the users are berating a set number or timer for each minute. Moreover, the difference in inhalation and exhalation pressure reduces the stressful breathing and lets the person have a very comfortable sleep.
  • The CPAP devices, on the other hand, are used to treat mild or moderate sleep apnea conditions. Based on the severity of sleep apnea, if you need a moderate level of pressure setting, the CPAP machines are the most comfortable one’s for you. On the other hand, if you have severe sleep apnea, then your doctor may recommend you to opt to form the BIPAP machines for a high level of pressure setting.

When should you pick the BIPAP machine over CPAP?

To receive the proper level of treatment for your comfort during sleep, you need to choose the right machine for you. Both the use of the BIPAP machine and CPAP machine is based on your needs for the pressure settings. Each of the devices responds differently to its respective treatment methods.

So, if you are having a moderate to a mild level of sleep apnea, then the CPAP machines are going to be the suitable choice for you. The CPAP devices offer a very moderate and steady pressure setting which is great to treat your needs for single pressure needs.

On the other hand, the BIPAP machines work with the double pressure ways, which deliver a very comfortable pressure of the air when you have severe obstructive sleep apnea. Moreover, if you are facing problems during exhaling through your CPAP machine, then it is time to consult your physician to make your switch to the BIPAP devices.


Both the BIPAP and CPAP devices work very conveniently as per your need. All you need to ensure is, you are picking the right device for your proper pressure setting so that you can get the constant delivery of the comfortable airflow so that you can have a satisfactory healthy sleep every time.
