The Difference Between Machines
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.
