IRONICS Chapter 3 Specifications Features Descriptions and Theory of Operation 3 4 Functional Description The BiPAP Synchrony is a noninvasive pressure support ventilator used to augment the breathing of adult patients gt 66lbs gt 30 kg suffering from acute or chronic respiratory insufficiency or to maintain airway patency and provide ventilatory support to patients who experience obstructive sleep apnea The Synchrony is not intended to provide the total ventilatory requirements of the patient The Synchrony is intended for use in the home but may be also be used in the hospital or other institutional settings The Synchrony is intended for use with nasal masks and full face masks as recommended by Respironics Bi level ventilation with the Synchrony Ventilatory Support System helps you to breathe by supplying two levels of air pressure The Synchrony provides a higher pressure known as IPAP Inspiratory Positive Airway Pressure when you inhale and a lower pressure known as EPAP Expira tory Positive Airway Pressure when you exhale The higher pressure makes it easier to inhale and the lower pressure makes it easier to exhale while still keeping your airway open Integral to the generation of air flow is the blower assembly Ambient air is drawn through the air intake filter and pressurized by the energized blower Ultimately therapeutic pressure is provided to the patient via the patient circuit The control circu
