Routine Maintenance
1. On a routine basis, check the CPRmeter’s status light. If the status light is
not flashing green every 5 seconds: See Chapter 7, Troubleshooting Guide.
2. On a routine basis, check that the CPRmeter has a patient adhesive in place
and that the liner remains on it. Replace the patient adhesive at least every
2 years if it is not used.
3. Replace the battery at least every 2 years. Replace the patient adhesive
every time the rear cover is opened.
Battery Monitoring
The CPRmeter continuously monitors the power of its battery. If the
remaining power is less than that required for an entire CPR event, the
following visual indicators signal that the battery should be replaced before
the next use:
– The green status light does NOT flash green
every 5 seconds when the CPRmeter is turned
off.
– A small battery-low icon is shown in the upper
right corner of the display when the CPRmeter
is being turned on.
– A large battery-low icon is shown on the display
when the CPRmeter is being turned off.
IMPORTANT NOTE: If the remaining battery
power during use becomes too low to sustain further operation, the battery-
low icon is shown for 10 seconds and then the CPRmeter turns itself off.
WARNING: Do not interrupt CPR to replace the battery. Continue CPR
without feedback from the CPRmeter.
Battery Replacement
1. Remove the CPRmeter patient adhesive from the back of the CPRmeter.
2. Unscrew the rear cover using a flathead screwdriver (not supplied) or a
coin, and lift out the cover.
3. Remove the old battery and discard.
4. Insert a new battery into the battery well, in the orientation as directed
by the battery symbol inside the well. See Chapter 12, Specifications, for
battery specifications.
5. Ensure that the rear cover’s vent membrane is not soiled or broken.
6. Position the rear cover on the CPRmeter. Thread the screws through the
washers and into the cover, and tighten the screws.
7. Apply a new CPRmeter patient adhesive to the CPRmeter as described in
Chapter 2, Setup.
