Place electrodes for a surgical patient
While placing electrodes for a surgical patient, the type of surgery should
be considered, for instance, as to a chest surgery, the chest lead electrodes can
be placed at sides or backside of chest. Moreover, while using a surgical
electrotome, in order to reduce the influence of artifacts to ECG waveform,
the electrodes can be placed at left and right shoulders, close to left and right
sides of abdomen; the chest lead electrodes can be placed at left side of chest
midst. Please avoid placing the electrode at the upper arms, otherwise the
ECG waveform will become very small.
