First Analysis Cycle
When you turn on the power and first apply electrodes to the patient, the AED will either analyze
automatically or prompt you to press
ANALYZE, depending on the auto analyze configuration.
If you hear the
PUSH ANALYZE voice prompt and see the ANALYZE LED flash, press ANALYZE.
When the AED begins to analyze the patient's ECG, the AED beeps twice and alternately displays two
messages:
You will hear the STAND CLEAR, ANALYZING NOW, STAND CLEAR voice prompt. The ECG analysis
requires about 9 to 13 seconds. The
ANALYZE LED (if present) is on during analysis.
Shock Advised
If the AED detects a shockable ECG rhythm, it displays this message:
You will hear the
SHOCK ADVISED voice prompt. The AED begins charging for Shock #1. A rising tone
indicates that the AED is charging.
When charging is complete, the AED alternately displays two messages:
You will hear the
STAND CLEAR, PUSH TO SHOCK voice prompt followed by the “shock ready” tone (a
loud, high-pitched, two-tone sound). The
SHOCK LED flashes.
• Check that no one is touching the patient.
•Press
SHOCK to discharge the AED.
• If you do not press
SHOCK within 15 seconds, the AED disarms the SHOCK button, and the CHARGE
REMOVED
message appears.
WARNING!
Possible misinterpretation of data.
Do not analyze in a moving vehicle. Motion artifact may affect the ECG signal resulting in an
inappropriate shock or no shock advised message. Motion detection may delay analysis. Stop vehicle
and stand clear of patient during analysis.
Possible misinterpretation of data.
Do not move the AED during analysis. Moving the AED during analysis may affect the ECG signal
resulting in an inappropriate shock or no shock advised decision. Do not touch the patient or the AED
during analysis.
