Electrode Position for Respiration Monitoring
Place the R/RA and F/LL electrodes so that the lungs are between the electrodes.
NOTE
The optimum electrode positions for ECG measurement of a patient are not always
optimum for respiration measurement of the patient. Select positions suitable for both ECG
and respiration measurements, or positions which have priority for one measurement.
Electrode Position Examples
NOTE
The following examples are when monitoring with 3 electrodes. ECG cannot be monitored
correctly when electrodes are attached as the following examples when monitoring with 6
electrodes.
Position 1
In this position, respiration measurement is available; however, there is a difference in amplitude
between different patients.
R or RA F or LL
Right infraclavicular fossa
Fifth intercostal space on the
left midclavicular line, V4
Position 2
In this position, the waveform amplitude is usually large and the ECG lead is similar to Lead MII.
This position can be generally recommended.
R or RA F or LL
Right infraclavicular fossa
Fifth intercostal space on the
left midaxillary line, V6
