Preparing for heart rate and apnea monitoring 53
When new electrodes have become detached you can reattach these
by pressing them gently.
You must replace electrodes that have become detached more than
once or that exhibit too high a resistance between the electrode and
skin. Further explanations can be found in the section “Checking the
basal impedance
” on page 55.
6.4 Determining the optimal electrode
configuration
The respiration and heart signals are detected using the same elec-
trodes. The optimal electrode configuration involves finding good
signal amplitudes for both the respiration and the heart signals
simultaneously.
getemed AG recommends that the responsible doctor determine the
optimal electrode configuration. In most cases this configuration can
be retained for the whole period of monitoring.
6.4.1 ECG lead, electrode color coding
Start with the electrode configuration depicted in Fig. 27 (see next
page). First arrange
the electrodes on infants as depicted in Fig. 27 a)
(this electrode configuration has often proved successful because
the abdominal wall of infants clearly moves synchronously with
the respiration),
the electrodes on all other patients as depicted in Fig. 27 b)
