Placing the Electrodes
As the Respiration measurement adopts the standard ECG electrode placement, you can use different ECG
cables. Since the respiration signal is measured between two ECG electrodes, if a standard ECG electrode
placement is applied, the two electrodes should be RA and LA of ECG Lead I, or RA and LL of ECG Lead II.

8.4.4 ECG Electrode Placements
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. This is particularly important
for neonates.
•
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 (especially neonates) 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.
•
To optimize the respiration waveform, place the RA and LA electrodes horizontally when monitoring
respiration with ECG Lead I; place the RA and LL electrodes diagonally when monitoring respiration
with ECG Lead II.
•
Periodically inspect the electrode application site to ensure skin quality. If the skin quality changes,
replace the electrodes or change the application site.
NOTE
•
Store the electrodes at room temperature. Open the electrode package immediately prior to use.
•
Check that the electrode packages are intact and not expired. Make sure the electrode gel is moist.
