Frequently Asked Questions

  • What does a high priority alarm indicate?

    High-priority alarms require immediate attention to ensure patient safety. During a high-priority alarm, the red high priority indicator flashes rapidly, the high-priority audible alarm (a sequence of five tones that repeats twice, pauses, then repeats again) sounds, and the top of the upper screen flashes an alarm message. If a high-priority alarm goes away spontaneously (auto resets), its indicator remains lit (not flashing) until you press the alarm reset key.

    Refer to the Puritan Bennett™ 840 Operators and Technical Reference Manual's "How to Handle Alarms" section for more information.

  • What does a medium priority alarm indicate?

    Medium-priority alarms require prompt attention. During a medium-priority alarm, the yellow medium-priority indicator flashes slowly, the medium-priority audible alarm (a repeating sequence of three tones) sounds, and the upper screen flashes an alarm message. If a medium-priority alarm auto resets, the indicator turns off and the auto reset is entered in the alarm history log.

    Refer to the Puritan Bennett™ 840 Operators and Technical Reference Manual's "How to Handle Alarms" section for more information.

  • What does a low priority alarm indicate?

    Low-priority alarms tell you that there has been a change in the patient-ventilator system. During a low-priority alarm, the yellow low-priority indicator lights, the low-priority audible alarm (two tone, non-repeating) sounds, and the upper screen displays an alarm message. If a low-priority alarm auto resets, the indicator turns off and the auto reset is entered in the alarm history log.
