  • Page 11: Warnings And Cautions

    • To avoid injury to the patient airway, DO NOT use the BiPAP Focus where ambient room temperature is above 95 °F (35 °C) because outlet gas temperature may exceed 106° F (41°C).
  • Page 12 Explosion hazard. Do not operate the ventilator in the presence of flammable anesthetic agents. • To avoid the risk of fire, use only Respironics-approved batteries. All battery connectors are keyed to ensure proper connection. Do not attempt to connect a battery incorrectly.

  • Page 13: Cautions

    If a 343 error code is displayed, remove the battery and charge it using the BiPAP Focus battery charging cable (P/N 1040421). This cable provides the initial charge required so that the ventilator can recharge a depleted battery. Refer to the battery charge instructions supplied with the cable.

  • Page 14: Notes

    Chapter 2 Warnings and Cautions 2.3 Notes • Refer to the BiPAP Focus Operator’s Manual for product use, additional warnings, cautions, and notes. • Service calibration procedures require a printer to be assigned to the service PC: this can be an internal print location (for example, using Adobe PDF) or a printer connected to the PC.

  • Page 15: Theory Of Operation

    AC power conditions occur. The system displays a real- time estimated delivered pressure bar graph. The BiPAP Focus includes alarm silence and alarm pre-silence features. A fully charged backup battery provides a minimum of 45 minutes of backup power at default settings in case AC power is not available (for example, during transport within the hospital).
