At Secondwind CPAP, we want to make sure you have all the information you need to make the best decision for your treatment.

What Is A CPAP Machine?
CPAP stands for Continuous Positive Airway Pressure. A CPAP machine helps people who suffer from sleep apnea by blowing air into their lungs through a mask to keep their airway open.

How Does A BiPAP Machine Differ From A CPAP Machine?
Instead of continuous, a BiPAP machine is a Bi-Level Positive Airway Pressure. It is similar to a CPAP machine in that it also blows air into the lungs through a mask, but the BiPAP has two different settings — one for inhaling and one for exhaling. This can make it more comfortable for some people to use than a CPAP machine.

How Often Do I Need to Replace My CPAP or BiPAP Supplies?
It is recommended that you replace your CPAP mask every three to six months and your CPAP filter every month. However, this will depend on how often you use your machine and what type of filter you have.
