CPAP (continuous positive airway pressure) is a common treatment that uses mild air pressure to keep the airways open. CPAP typically is used by people who have breathing problems, such as obstructive sleep apnea . It includes a small machine that supplies a constant and steady air pressure, a hose, and a mask or nose piece.
A Bilevel positive airway pressure (or BiPAP) machine builds to a higher pressure when you inhale and decreases to a lower pressure when you exhale. This device is most appropriate for central sleep apnea, a condition where the brain loses its drive to breathe. A BiPAP device looks and fits very much like a CPAP device, but the functionality is different.
An oxygen concentrator is a device providing oxygen therapy to a patient at higher concentrations than available in ambient (room) air. Concentrators are used as a safer, less expensive, and more convenient alternative to tanks of compressed oxygen.
Cushion/Pillows - Cushion/Pillows are the parts that touch your skin and create a seal for your CPAP or Bi-Level Therapy. These can typically be replaced monthly.
Mask Frame - Mask frame is typically the less-flexible plastic portion of the interface that the cushion fits into. New technology has changed the way that many mask frames look recently – but believe it or not, each and every CPAP interface does have a mask frame. Typically, you can replace your mask frame every 3 months.
