By delivering a constant stream of pressurised air through a mask, Cpap machines increase the pressure inside the upper airway just enough to keep the soft tissues from falling inward.

By delivering a constant stream of pressurized air through a mask, Cpap machines increase the pressure inside the upper airway just enough to keep the soft tissues from falling inward.

The invention provides an improved design for a CPAP machine. In doing so, it ensures the machine can operate even during a power outage. As a result, it increases safety.
