INTRODUCTION
BIPAP SYNCHRONY VENTILATORY SUPPORT SYSTEM OVERVIEW
The BiPAP Synchrony, shown in Figure A, is a low-pressure, electronically driven ventilator system
with electronic pressure control. The device’s pressure controls are adjusted to deliver pressure
support for patient ventilatory assistance.
FIGURE A: BIPAP SYNCHRONY DEVICE
The BiPAP Synchrony is intended to augment patient breathing by supplying pressurized air through a
patient circuit. It senses the patient’s breathing effort by monitoring airflow in the patient circuit and
adjusts its output to assist in inhalation and exhalation. This assistance is provided by the
administration of two levels of positive pressure. During exhalation, pressure is variably positive or
near ambient. During inspiration, pressure is variably positive and always equal to or higher than the
expiratory level.
The BiPAP Synchrony responds reliably to patient flow rates that indicate movement to inhalation or
exhalation, even in the presence of most normal leaks in the patient circuit. Automatic adjustment of
this trigger threshold in the presence of leaks makes the system ideal for mask-applied ventilation
assistance. The patient-controllable Rise Time and Bi-Flex features may enhance patient-ventilator
synchrony and patient comfort.
The BiPAP Synchrony operates in the following modes: Continuous Positive Airway Pressure (CPAP),
Spontaneous (S), Spontaneous/Timed (S/T), Timed (T), and Pressure Control (PC).
In the Continuous Positive Airway Pressure (CPAP) mode, the BiPAP Synchrony delivers continuous
pressure support ventilation at one pressure level.
In the Spontaneous (S) mode, the BiPAP Synchrony delivers bi-level pressure support. The device
triggers to Inspiratory Positive Airway Pressure (IPAP) in response to spontaneous inspiratory effort
and cycles to Expiratory Positive Airway Pressure (EPAP) during exhalation. The level of pressure
support delivered is determined by the difference between the IPAP and EPAP settings. The
Spontaneous/Timed (S/T) mode of the BiPAP Synchrony is similar to the S mode, except that it also
can deliver a machine-triggered breath if the patient does not spontaneously breathe within a set time.
