CAUTION
：
Correct electrodes placement can help to reduce cardiac overlay: avoid the
liver area and the ventricles of the heart in the line between the respiratory
electrodes.
Some patients with restricted movements breathe mainly abdominally. In these
cases, you may need to place the left leg electrode on the left abdomen at the
point of maximum abdominal expansion to optimize the respiratory wave.
In clinical applications, some patients expand their chests laterally, causing a
negative intrathoracic pressure. In these cases, it is better to place the two
respiration electrodes in the right midaxillary and the left lateral chest areas at
the patient’s maximum point of the breathing movement to optimize the
respiratory waveform.
Regularly inspect the electrode application site to ensure skin quality. If there
are signals of allergies, change the clip application site.
9.4.1.
Optimizing Lead Placement for Resp
If you want to measure Resp and you are already measuring ECG, you may need to
optimize the placement of the two electrodes between which Resp will be measured.
Repositioning ECG electrodes from standard positions results in changes in the ECG
waveform and may influence ST and arrhythmia interpretation.
