What’s the Difference Between CPAPs, APAPs and BiPAPs?


CPAPs: One Set Pressure

CPAP stands for Continuous Positive Airway Pressure

CPAPs are ”titrated“ to blow air at a constant set pressure that will keep air passages open. They are the most common way to treat Sleep Apnea.

APAPs: Best Pressure Within Set Range

APAP stands for Automatic Positive Airway Pressure

APAPs are set to disperse air at a range of pressures, constantly adjusting to the minimum pressure needed to keep airways open. The breath-by-breath adjustments maximize comfort. A CPAP prescription can be used to buy an APAP.

BiPAPs: Different Inhale/Exhale Pressures

BiPAP stands for BiLevel Positive Airway Pressure. Sometimes they are called BiLevel Machines.

BiPAPs blow air at two distinct pressures: one at inhalation and another at exhalation. BiPAPs require a specific prescription.
