    I. PATIENT SAFETY , WARNINGS, CAUTIONS AND NOTES The CROSSVENT-3+ ventilator is intended for use only by a qualified practitioner, under the direction of a qualified physician. All personnel operating the ventilator must be completely familiar with the warnings and operating procedures in this manual prior to using the CROSSVENT-3+ with patients. As with any life support device, the patients on the CROSSVENT-3+ should be visually monitored by competent personnel at all times since life threatening conditions may arise that may not be detected by the alarms.
  • Page 8 • All safety measures must be observed when servicing this device. In particular, the ventilator must be turned off and the power supply disconnected. • Bio-Med Devices cannot be held responsible for any failure to adhere to the recommendations set forth in this manual.
  • Page 9 O N T . • Because this is a CE marked device, it must never be modified without prior expressed written consent from Bio-Med Devices. • When setting Pressure Trigger, auto-triggering or missed breaths may occur due to various conditions including, but not limited to, compliance, resistance, rate, flow, PEEP, I:E ratio, and circuit characteristics.

  • Page 10: Cautions

    After discharge of the battery, recharge fully before disconnecting the plug-in power supply. • Only replace the battery pack with Bio-Med Devices part #PRT4467. Do not substitute. The cells are non-standard high capacity. • When using an AC power source, only the power supply provided with the Crossvent is approved for use with this ventilator.

  • Page 11: Notes

    When this sensor is off, it may be disconnected while the ventilator is in use, without causing an alarm. • For blended gas, the Bio-Med Devices blender should be used. • It is recommended that an external filter/water trap be used at all times in order to provide greater protection to the internal components of the CROSSVENT.
  • Page 12 • Prior to disposal of any component, with particular attention to the battery and PCB, check with your local controlling authority for disposal regulations. • When first turned on, the unit displays “Bio-Med Devices, Inc.” until the initialization process is complete. If this does not clear, submit unit for service.
