What is Bi-level Ventilation?

Bi-level ventilation with the Synchrony VentilatorySupport System helps you to breathe by supplying twolevels of air pressure. The Synchrony provides a higherpressure—known as IPAP (Inspiratory Positive AirwayPressure)—when you inhale, and a lower pressure—known as EPAP (Expiratory Positive Airway Pressure)—when you exhale. The higher pressure makes it easier toinhale and the lower pressure makes it easier for you toexhale.

The Synchrony can also provide a single pressure level,known as CPAP (Continuous Positive Airway Pressure).

If you require a higher level of ventilatory support, theSynchrony can be upgraded to provide modes ofventilation that reinforce your breathing with machine-triggered breaths.

What is the Synchrony?

The Synchrony, shown in Figure 2-2, supplies air pressurethrough a breathing circuit. The circuit, shown in Figure2-3, consists of:

• circuit tubing to deliver the air from the Synchrony toyour interface (e.g., mask)

• a mask or other interface to deliver the prescribedpressure to your nose or nose and mouth, depending onwhich interface has been prescribed for you

• an exhalation port to vent exhaled air from the circuit

NOTE: The exhalation port may be part of the mask ormay be part of a separate exhalation device.

The system senses your breathing effort and changespressure levels when you inhale and exhale depending onthe mode of operation.

The Synchrony can operate on AC or DC power. The DCpower option is not intended as a battery backup. WhenDC power is obtained from a vehicle battery, the Syn-chrony should not be used while the engine of the vehicleis running.
