Using the LIFEPAK 500 AED
3 Using the LIFEPAK 500 AED
You will hear the MOTION DETECTED, STOP MOTION voice prompt, followed by a warning tone. If the
motion ceases within 20 seconds, analysis will continue. If the motion does not cease within
20 seconds, analysis will stop. You must then push
ANALYZE (if button present) to restart analysis. If
AUTO ANALYZE 2 is selected and in LIFEPAK 500 AEDs that do not have an ANALYZE button, analysis will
restart automatically. Refer to troubleshooting on page 6-2 for possible causes and suggested actions.
If the AED is configured with
MOTION DETECTION OFF, the ECG analysis proceeds uninhibited by the
presence of motion. There is no motion detected verbal or text prompt if motion is present during ECG
analysis.
Continuous Patient Surveillance System — Check Patient Alert
The Continuous Patient Surveillance System (CPSS) is active immediately after the AED is turned on
when the patient is connected, and after CPR time. In addition, CPSS may be configured to be active
during CPR time.
Note: CPSS is not active if
AUTO ANALYZE 2 is selected or in LIFEPAK 500 AEDs without an ANALYZE
button.
If the CPSS detects a potentially shockable rhythm, the AED displays this message:
You will hear the
PUSH ANALYZE voice prompt accompanied by a warning tone. You should:
• Stop all patient and vehicle movement.
• Confirm that the patient is in cardiac arrest.
•Press
ANALYZE. Stay clear of the patient and allow the AED to analyze the patient’s rhythm.
• Follow the screen messages and voice prompts provided by the AED.
Electrodes Off Detection
If the AED detects that the electrodes are not properly connected to the AED or the patient, the AED
displays this message:
You will hear the
CONNECT ELECTRODES voice prompt followed by three warning beeps. Refer to
troubleshooting on page 6-2 for possible causes and suggested actions.
Asystole Detector
If the AED has been configured for the asystole detector to be active, the AED displays this message
after
NO SHOCK ADVISED decisions occur with asystole present and when the asystole detector time
interval has been reached.
You will hear the
ASYSTOLE voice prompt, which will repeat periodically until the next analysis.
