12.4 Preparing for Resp Monitoring
12.4.1 Preparing the Patient
Follow this procedure to prepare the patient:
1. Shave hair from skin at chosen sites.
2. Gently rub skin surface at sites to remove dead skin cells.
3. Thoroughly cleanse the site with a mild soap and water solution.
4. Dry the skin completely before applying the electrodes.
CAUTION
• Proper skin preparation is necessary for good signal quality at the electrode site, as the skin is a poor
conductor of electricity.
12.4.2 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.
For more information, see
12.4.2 Placing the Electrodes.
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
(1) Lead I (2) Lead II
