Introduction |
| If there are alarm conditions sounding when they shouldn’t be, or if alarms are not sounding when they should be, you will need to use this guide to reset the audio of the Puritan Bennett 540. You will not need any tools or parts besides the ventilator itself. There are no difficult steps, but please pay close attention to the warnings before starting this guide. | | | | | '''Warnings:''' | | | # When an alarm is triggered, or there is evidence of a patient-ventilator problem, examine the patient first before examining the ventilator. | | # Handle respirator with care, as it may be very hot. | | # Double-check the alarm volume after you have finished working on the alarms, it should be loud enough for the patient’s caretaker to hear. |
