The DreamStation BiPAP Auto is an evolved, sleek and modern, low-profile machine offering important advanced features users were looking for to increase therapy effectiveness and comfort. This unit is a bilevel machine that provides one distinct higher pressure for inhalation, and a separate lower pressure for exhalation. During therapy the machine will monitor the user on a breath-by-breath basis and remain at a lower pressure until an event is detected. When an event is detected that requires a higher pressure, the machine will automatically increase to the needed pressure and return to a lower pressure when the event has concluded.
