8.3 Placing electrodes for respiration monitoring
Since the skin is a poor conductor, it is very important to treat the patient's skin for electrode
placement appropriately to get better respiration signals. Refer to 7.3.1.
Respiration measurement uses standard ECG cable and electrode placement method. You can
use different ECG cables (3-lead or 5-lead). Respiratory signal is measured between two ECG
electrodes. If standard ECG electrode position is used, the two electrodes are R (right arm) and
L (left arm) electrodes of I lead or R (right arm) and F (left leg) electrode of II lead.
NOTE
For optimal respiration wave, R and L electrodes should be placed horizontally if
I lead is selected for respiration measurement. R and F electrodes should be
places diagonally if II lead is selected for respiration measurement.
Figure 8-1 below shows the placement of 5-lead electrodes.

8.3.1 Adjusting position of respiration electrode
If you want to measure ECG and respiration simultaneously, you may need to adjust the
position of the two electrodes for respiration measurement.
NOTE
Adjusting the standard position of ECG electrodes will lead to changes in the ECG
wave, and may affect the ST and arrhythmia analysis.
