Acquiring a 12-Lead ECG

LIFEPAK 15 Monitor/Defibrillator Operating Instructions
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 general, it is best to wait at least 30 seconds after applying the last electrode before pressing
the
12-LEAD
button, to allow for electrode/skin stabilization. Also, good skin preparation
shortens the stabilization time.
Computerized ECG Analysis
Computerized ECG analysis statements are automatically printed on 12-lead ECG reports.
Printing of the interpretive statements is a setup option and may be turned off in Setup mode.
For information on how to change this setup option, see the
LIFEPAK 15 Monitor/Defibrillator
Setup Options provided with your device.
