10.8.2 Electrode Placement

Since the same electrodes are used for ECG and respiration monitoring, the electrode placement

is very important. Some patients, due to their clinical condition, expand their chest laterally,

causing a negative intrathoracic pressure. In these cases it is better to place the two electrodes

used for respiration monitoring laterally in the right axillary and left lateral chest areas, at the

maximum point of the breathing movement, to optimize the respiratory waveform.

NOTE

z To optimize the respiration waveform, place the RA and LA electrodes

horizontally when the ECG Lead I is selected, and place the RA and LL

electrodes diagonally when the ECG lead II is selected.

z Try to avoid placing the electrodes so the liver area and the ventricles of the

heart are in path between the electrodes used for respiration, to avoid cardiac

artifact to overlay on the ECG. This is particularly important when monitoring

neonate patients.
