that a shock is needed, the AED will prompt, IF YOU WITNESSED THE ARREST, PUSH
CANCEL , which provides the opportunity to end CPR early and proceed directly to delivering
a shock.
• The CPR FIRST setting prompts the user to perform CPR immediately after the defibrillator is
powered on. The AED will also prompt, IF YOU WITNESSED THE ARREST, PUSH CANCEL ,
which provides the opportunity to end CPR early and proceed directly to analysis.
Organizations that choose to implement this option should develop a protocol and provide
training to responders instructing them when to end the initial CPR interval early. Potential
situations for instructing responders to end CPR early include:
• The patient's collapse was witnessed by the responder.
• The responder ascertains that fewer than four or five minutes have elapsed since the patient's
collapse.
• The patient exhibits agonal breathing, an indicator of a short downtime.
• The responder ascertains that CPR of adequate quality and duration has already been
provided before attaching the AED electrodes.
Initial CPR Time
The INITIAL CPR TIME option applies when INITIAL CPR is set to ANALYZE FIRST or CPR
FIRST . It sets the CPR time for that CPR period. The time choices for INITIAL CPR TIME are: 15 ,
30 , 45 , 60 , 90 , 120 , and 180 SECONDS . The default setting is 120 SECONDS .
PreShock CPR Time
The PRESHOCK CPR time option inserts prompting for CPR when a shockable ECG rhythm is
detected and during the time the AED is charging. It applies only when analysis results in
SHOCK ADVISED decisions. When INITIAL CPR is set to OFF or CPR FIRST , PRESHOCK CPR
time applies to the first and all subsequent shocks. When INITIAL CPR is set to ANALYZE FIRST ,
PRESHOCK CPR time applies to the second and all subsequent shocks. The choices for
PRESHOCK CPR time are: OFF, 15, and 30 SECONDS . To prompt for CPR only for the time the
capacitor is charging, select the 15-seconds CPR interval. The SHOCK button is not enabled
until charging and CPR time are completed. The default setting for PRESHOCK CPR time is OFF .
Note: Although the SHOCK button is disabled during the PRESHOCK CPR interval, it
becomes active as soon as the PRESHOCK CPR interval ends. To minimize the interval
between the final chest compression and shock delivery (while maintaining responder
safety), protocols that select this option should provide specific training and protocols to
address the rapid transition from
PRESHOCK CPR to shock delivery.
Stacked Shocks
When set to OFF , the STACKED SHOCKS option inserts prompting for CPR after each (a single)
shock. This eliminates the three-shock stack. CPR is prompted after the shock regardless of the
ECG rhythm. The CPR time following the shock is determined by the
CPR TIME 1 setting
selected. Choices for the STACKED SHOCKS option are ON or OFF . The default setting is OFF .
When this option is set to ON , the defibrillator follows the previously traditional stacked shock
protocol and delivers up to three consecutive shocks, as necessary, without interposed CPR.
