CPR Voice Prompts
The X Series unit can be configured to issue voice prompts related to the depth of chest
compressions as feedback to rescuers performing CPR. Two voice prompts are available for
this purpose:
• Push Harder
• Good Compressions
When chest compressions are detected but their depth is consistently less than the target depth
(AHA/ERC 2005: 1.75, AHA/ERC 2010: 2.0), the device periodically issues the “Push Harder”
voice prompt. If the rescuer responds by increasing compression depth to more than the target
depth on a consistent basis, the unit issues a “Good Compressions” prompt.
CPR Metronome
The X Series unit includes 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.
The CPR metronome can be configured to operate in all modes (AED, Manual, and Advisory/
CPR Protocol), or in AED mode only. The CPR metronome can also be disabled for all modes.
When activated, the metronome beeps at the AHA/ERC recommended rate to provide a
compression rhythm for rescuers to follow.
The CPR metronome’s Constant Metronome feature allows the metronome to continue beeping
under certain circumstances. When Enable Metronome is set to Never in the Supervisor>CPR
menu, Constant Metronome is greyed out.
The CPR metronome can be configured as follows.
Constant Metronome Enabled
AED Mode
• If Enable Metronome is set to Always or AED Mode Only, the metronome is active when
chest compressions are first detected during the CPR interval. The metronome is silent when
the CPR idle timer starts.
• If set to Never, the metronome is silent.
Advisory/CPR Protocol or Manual Mode
• If Enable Metronome is set to Always, the metronome is active when chest compressions
are first detected during the CPR interval. The metronome is silent when the CPR idle timer
starts.
• If set to AED Mode Only or Never, the metronome is silent.
