LIFEPAK 15 Monitor/Defibrillator Operating Instructions
Acquiring a 12-Lead ECG
6. Encourage the patient to remain as still as possible.
7. Press 12-LEAD . The 12-LEAD / AGE menu appears, prompting you to enter the patient’s age.
Use the SPEED DIAL to select the age. Always enter the patient’s age if the patient is 15 years old
or younger. If you do not enter an age, the default value of 50 years is used by the interpretive
analysis program and annotated on the 12-lead ECG report.
8. The 12-LEAD / SEX menu appears, prompting you to enter the patient’s sex.
Use the SPEED DIAL to select the patient’s sex. If you do not enter the sex, the default of male is
used by the interpretive analysis program and is annotated on the 12-lead ECG report.
The monitor acquires, analyzes, and automatically prints the 12-lead ECG. An ECG leads-off
condition for any lead is indicated on the report by a dashed line.
Note: If 15 years or less is entered for patient age, the 12-lead ECG prints at diagnostic frequency
response of 0.05–150 Hz, even when 0.05–40 Hz is set up as the print default.
Note: When 12-LEAD is pressed, internal pacemaker detection is automatically enabled, even if the
function is set up to be OFF.
ECG Override
If the monitor detects signal noise while acquiring data (such as patient motion or a disconnected
electrode), the screen displays the message: NOISY DATA! PRESS 12-LEAD TO ACCEPT . The message
remains and 12-lead ECG acquisition is interrupted until noise is eliminated. Take appropriate
action to eliminate the signal noise. This message remains as long as signal noise is detected.
When signal noise is eliminated, the monitor resumes acquiring data. To override the message and
acquire the 12-lead ECG in spite of the signal noise, press 12-LEAD again. The 12-lead ECG will be
acquired and printed with no interpretive statements. Any 12-lead ECG report acquired in this way
is annotated with the following statement: ECG OVERRIDE: DATA QUALITY PROHIBITS INTERPRETATION .
If the signal noise persists for longer than 30 seconds, 12-lead ECG acquisition stops. The screen
displays EXCESSIVE NOISE–12-LEAD CANCELLED . You must then press 12-LEAD to restart 12-lead ECG
acquisition.
Note: If 12-LEAD is pressed immediately after ECG electrodes are applied, the message NOISY DATA
may occur. This message is due to the temporary instability between the electrode gel and the
patient’s skin that is not viewable on the ECG monitor screen, but is detected as noisy data. In
WARNING
POSSIBLE INACCURATE DIAGNOSIS
If age and sex are not entered when a 12-lead ECG is obtained, the interpretive
statements are based on a default of a 50-year-old male and may provide incorrect
analysis for that patient.
