Display Screen
The display screen shows the following items (depending on the activity in progress):
Elapsed time — Shows the total time (in hours, minutes, and seconds) since the unit was
turned on. The counter resets to 00:00:00 after 23 hours, 59 minutes, and 59 seconds, or when
the unit is turned off.
ECG size — Shows the amplitude scale for the displayed ECG in centimeters per millivolt
(cm/mV). The device adjusts the scale automatically. The ECG scale marker always indicates
the size of a 1 mV peak-to-peak signal.
Heart rate and heartbeat symbol — (Manual and ECG monitoring modes only) Shows the
current heart rate in beats per minute. The symbol flashes with each detected heartbeat.
Chest compression depth gauge— Shows the depth of chest compression during CPR when
ZOLL CPR-D•padz are connected. The bar extends downward as the depth of compression
increases, with scale marks representing 0, 2.0 inches, and 2.4 inches.
Softkey labels — Labels for the softkeys appear at the bottom of the display directly above
each softkey to indicate its function.
Text prompts and messages — In semiautomatic mode, text prompts guide the rescuer. In all
modes, messages alert the operator about problem conditions.
ECG rhythm — Displays the patient’s ECG.
Shock symbol and number of shocks delivered — Shows the number of shocks delivered
since the unit was powered on.
