    • The Synchrony should be used only with masks and connectors recommended by Respironics or with those recommended by the health care professional or respiratory therapist. See Chapter 12 for approved patient circuits. A mask should not be used unless the Synchrony is turned on and operating properly.
  • Page 10 Respironics or an authorized service center. • Repairs and adjustments must be performed by Respironics or an authorized service center. Service done by inexperienced or unqualified personnel, or installation of unauthorized parts could cause injury, invalidate the warranty, or result in costly damage.

  • Page 11: Cautions

    Warnings (continued) • Verify that the Patient Disconnect alarm is active if required for medical reasons. 1.2 Cautions • The Synchrony may only be operated at temperatures between 5°C and 35°C. • Do not immerse the Synchrony or allow any liquid to enter the enclosure or the inlet filter.

  • Page 12: Intended Use

    The Synchrony is intended for use with nasal masks and full-face masks as recommended by Respironics. WARNING! Do not connect any equipment to the Synchrony unless recommended by Respironics or the health care professional. Verify that an exhalation port is present to exhaust CO from the circuit.

  • Page 15: Chapter 2: Introduction

    The Synchrony is available in two models. The BiPAP Synchrony Lab System is for use by clinicians in a sleep lab setting. The BiPAP Synchrony Ventilatory Support System is for use in a hospital or home setting. Throughout this manual, references to “Synchrony” will apply to both the Lab System and the Ventilatory Support System unless otherwise noted.

  • Page 16: Modes Of Operation

    2.2 Modes of Operation 2.2.1 CPAP M In the Continuous Positive Airway Pressure (CPAP) mode, the Synchrony delivers a continuous pressure support ventilation at one pressure level. 2.2.2 The Spontaneous (S) mode of the Synchrony delivers bi-level pressure support. The unit triggers to Inspiratory Positive Airway Pressure (IPAP) in response to spontaneous inspiratory effort and cycles to Expiratory Positive Airway Pressure (EPAP) during exhalation.

  • Page 17: S/T Mode

    2.2.3 S/T M The Spontaneous/Timed (S/T) mode of the Synchrony is similar to the S mode, except that it also can deliver a machine-triggered breath if the patient does not spontaneously breath within a set time. The S/T mode ensures that patients will receive a minimum number of breaths per minute based on the Rate setting.

  • Page 19 Volume Trigger The volume trigger is one method used to trigger IPAP during spontaneous breathing in the S, S/T, and PC modes. The volume trigger threshold is 6 cc of (EPAP to IPAP) accumulated patient inspiratory volume. When patient effort generates inspiratory flow causing 6 cc of volume, IPAP is triggered.
  • Page 20 Spontaneous Expiratory A second method used to cycle off IPAP during spontaneous breathing in the S, S/T, and PC modes is called Spontaneous Expiratory Threshold (SET). The Threshold SET rises in proportion to the inspiratory flow rate on each breath. When the (IPAP to EPAP) Spontaneous Expiratory Threshold (SET) and actual patient flow value are equal, the unit cycles to EPAP.

  • Page 21: Access Levels

    2.4 Access Levels The Synchrony can be set to a Lockout mode so that certain settings and displays cannot be accessed. In the Lockout mode, the IPAP Rise Time can be adjusted if Bi-Flex is not enabled. If Bi-Flex is enabled, then it is adjustable in Lockout Mode.
