9.11 Changing the ECG lead for signal optimization
When the used lead frequently causes false heart rate alarms, an-
other lead can be chosen. The default is lead I YE-RD, 3 (yellow–red,
3 electrodes). Signals can be optimized only when the patient is still
or sleeping.
Bear in mind when optimizing the ECG lead that there must be no
changes to the optimized positions of the red and yellow electrodes
for detecting the respiration signal. When optimization becomes
necessary, only the black electrode must be repositioned.
When replacing the electrodes, always choose the same electrode
position and color.
To avoid too much of a strain on the patient’s skin, you can also
arrange the electrodes in a small circle around the optimal position.
By changing the ECG lead you can
optimize separately the detection
of respiration and heart signals for
VitaGuard®.
Fig. 69 Heart rate menu \ “Lead, Nr. of electrodes” submenu
I YE-RD, 3 (yellow–red, 3 electrodes)
Both signals, the heart and the respiration signal, are measured
between <yellow> and <red>.
II BK-RD, 3 (black–red, 3 electrodes)
Like lead I, the respiration signal is measured between <red> and
<yellow>, the heart signal on the other hand between <black> and
<red>.
III BK-YE, 3 (black–yellow, 3 electrodes)
Like lead I, the respiration signal is measured between <yellow> and
<red>, the heart signal on the other hand between <black> and
<yellow>.
