Display Energy
The DISPLAY ENERGY option determines whether or not the energy of the last shock is displayed during
use. The factory default setting is
ON.
Auto Analyze
The AUTO ANALYZE options are OFF, 1, or 2.
AUTO ANALYZE OFF: The operator must press ANALYZE to start every analysis.
AUTO ANALYZE 1: The second and third rhythm analyses of each three-shock set start
automatically without requiring the operator to press
ANALYZE. (The operator
must always press
ANALYZE to start the first analysis of a three-shock set and to
analyze after a
NO SHOCK ADVISED message or CPR cycle.) The factory default
setting is
AUTO ANALYZE 1.
AUTO ANALYZE 2: ALL analysis cycles are initiated automatically. LIFEPAK 500 AEDs that do not
have an
ANALYZE button operate in this mode.
CPR Time
The CPR TIME 1 AND 2 options define a time period during which you are prompted to perform CPR. The
choices are: 0, 15, 30, 45, 60, 90, 120, and 180 seconds and 999 (infinite CPR Time). For all selections
except 0 and 999, the AED prompts you to perform CPR and then displays a countdown timer. If CPR
Time 999 is selected, the AED prompts you to perform CPR, but does not display the countdown timer.
The AED will not prompt you to
PUSH ANALYZE, although you may do so at any time to initiate an
analysis.
CPR Time 1 defines the CPR period following each 3-shock set. CPR Time 2 defines the CPR period
following a
NO SHOCK ADVISED message. Check your local protocol for the appropriate CPR Time.
The
CPR TIME 1 AND 2 factory default settings are 60 seconds each.
Note: When a
NO SHOCK ADVISED message occurs immediately after a shock, the CPR period is the
same as CPR Time 1.
Note: CPR Time 0 is not available if
AUTO ANALYZE 2 is selected on AEDs that have an ANALYZE
button or on AEDs that do not have an
ANALYZE button. CPR Time 999 is not available on AEDs that
do not have an
ANALYZE button.
Pulse Prompt
The PULSE PROMPT option appears only on AEDs distributed in the English language.
This option determines which voice prompt (and LCD message) is presented to tell the user to check
the patient for signs of circulation. Checking for signs of circulation is important after a
NO SHOCK
ADVISED
decision, after three sequential shocks, and after a CPR interval.
If
PULSE PROMPT 1 is selected, the following voice prompts will be heard and LCD messages displayed:
CHECK FOR PULSE; IF NO PULSE, START CPR and CHECK FOR PULSE; IF NO PULSE, PUSH ANALYZE.
If
PULSE PROMPT 2 is selected, the following voice prompts will be heard and LCD messages displayed:
CHECK FOR SIGNS OF CIRCULATION; IF NO SIGNS OF CIRCULATION, START CPR and CHECK FOR SIGNS OF
CIRCULATION; IF NO SIGNS OF CIRCULATION, PUSH ANALYZE
.
The factory default setting is
PULSE PROMPT 2.
