Learning About Bilevel Positive Airway Pressure (BPAP)

What is BPAP?

BPAP stands for bilevel positive airway pressure. (You might also hear it called BiPAP.) It's a machine that gives you air through your nose, mouth, or both. It uses different pressures when you breathe in and out. Higher pressure is used when you breathe in. It may have a mask that covers your nose and mouth (this may be called a full face mask) or a mask that covers only your nose. It could also have a nasal pillow that covers only the openings of your nose.

Why is it used?

BPAP is used to treat conditions that make it hard to breathe. It can be used to treat obesity hypoventilation syndrome and certain lung conditions. Some people with obstructive sleep apnea use it instead of CPAP. It's sometimes used instead of a machine that requires a breathing tube in your windpipe.

How can you care for yourself at home?

  • Be sure the mask, nasal mask, or nasal pillow fits well.
  • If needed, see if the doctor can adjust the pressure of your BPAP. Some have air pressure that adjusts on its own.
  • If your nose or mouth is dry:
    • Set the machine to deliver warmer or wetter air.
    • Use a room humidifier or raise the room temperature. Follow the directions for cleaning the humidifier.
    • Try using a mask that covers your nose and mouth, if you're not already doing so.
    • Try heated tubing.
  • If your nose is runny or stuffy, talk to your doctor about using a decongestant medicine or steroid nasal spray. Be safe with medicines. Read and follow all instructions on the label. Do not use the medicine longer than the label says.
  • Your doctor may be able to help you with other problems like swallowing air, gas pain, or bloating. You can also get help with claustrophobia.
  • Talk to your doctor if you're still having problems. You may be able to try a different mask or make other changes to help you sleep through the night. If these things don't help, you might try a different type of machine.
