9.4.2. Cardiac Overlay
Cardiac activity that affects the Resp waveform is called cardiac overlay. It happens
when the Resp electrodes pick up impedance changes caused by the rhythmic blood flow.
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.
9.4.3. Abdominal Breathing
Some patients with restricted movement 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 optimise the respiratory wave.
9.4.4. Lateral Chest Expansion
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.
