CPR Compressions Indicator
This rectangular bar shaped figure provides a quick,
overall indicator of how well the rescuer’s combined rate
and depth of chest compressions match the AHA/ERC
recommendations for adult CPR.
Before chest compressions begin (and after each
shock), the Chest Compression Indicator is displayed as
a hollow outline. This indicator starts to fill as
compressions begin (filling from left to right), and
becomes fully filled when consistent chest compression
depth exceeding 1.75 inches and rate exceeding 90
compressions per minute (cpm) are achieved
simultaneously. Should the chest compression rate or
depth begin to fall below the AHA/ERC recommended
levels, the indicator will only partially fill to indicate the
need for more vigorous efforts. Following the cessation
of compressions, the indicator’s fill level gradually
decreases until a hollow outline is displayed after a short
period of time.
When complete filling of the CPR Compression Indicator
has not been achieved due to diminished compression
rate or depth, the M Series will display the letter R for
Rate and/or the letter D for depth to assist the rescuer in
determining whether chest compression rate or depth
should be increased. When an appropriate rate and
depth have been achieved, these letters will disappear
from the display field.
CPR Idle Time Display
This display indicates the elapsed time in minutes and
seconds since the last detected chest compression.
When compressions are being delivered at a rate of 11
cpm or higher, the idle time will not be displayed. Ten
seconds following the cessation of compressions, the
idle time will be displayed in place of the Compression
Indicator bar. As soon as a new compression is
detected, the idle time is removed from the screen. If no
compressions have been delivered for more than 20
minutes, dashes (---) will be displayed in this time field.
CPR Metronome
The M Series can be configured to include a CPR
metronome feature that can be used to encourage
rescuers to perform chest compressions at the AHA/
ERC recommended rate of 100 compressions per
minute. This metronome can operate in both semi-auto
and manual mode, or in semi-auto mode only.
When activated, the metronome beeps at the AHA/ERC
recommended rate to provide a compression rhythm for
rescuers to follow. The metronome is silent when no
chest compressions are being detected by CPR
equipped hands free electrodes.
In manual mode, the metronome only beeps when chest
compressions are detected and their rate falls below the
AHA/ERC recommended levels. When compressions
are being performed at 80 compressions per minute or
higher, the metronome is silent. Should the detected
compression rate fall below this level, the metronome will
begin beeping until recommended compression rates
are consistently achieved over several compression
cycles. The metronome stops beeping approximately 2
seconds after the last chest compression is detected.
In semiautomatic mode, the metronome is enabled
during all CPR periods. It begins to beep following
detection of the first few compressions and continues to
beep until the CPR period has ended or until
compressions have stopped for more than a few
seconds. If compressions are resumed during a CPR
period, the metronome will resume beeping following the
first few compressions.
