AED OPERATION WITH cprMAX TECHNOLOGY
The following paragraphs describe AED operation with cprMAX technology setup options.
Initial CPR
The INITIAL CPR option prompts the user to perform an initial period of CPR. The choices are:
OFF, ANALYZE FIRST and CPR FIRST. The factory default is OFF.
• The
OFF setting has no prompting for an initial CPR period.
• The
ANALYZE FIRST setting prompts for analysis and then CPR. If the analysis determines
that a shock is needed, the AED will prompt,
IF YOU WITNESSED THE ARREST, PUSH
ANALYZE
, 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 ANALYZE,
which provides the opportunity to end CPR early and proceed directly to analysis.
Hospitals 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.
Refer to Continuous Patient Surveillance System for a more detailed description of the AED
prompting sequence for each
INITIAL CPR option.
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 apples 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), hospital
protocols that select this option should provide specific training and protocols to address the
rapid transition from
PRESHOCK CPR to shock delivery.
