Patient Monitor User Manual Monitoring ECG/ RESP
- 116 -
WARNING
7 In manual detection mode, after changing the gain of the respiration wave, be sure to
check the setting of hold high and hold low.
8 When ECG electrode is placed on patient’s limb, the impedance respiration may be
unreliable.
9 Respiration measurement cannot be performed when ESU is used.
13.8.1 How to Measure RESP
The monitor measures respiration from the amount of thoracic impedance between two ECG
electrodes. The change of impedance between the two electrodes, (due to the thoracic movement),
produces a respiratory waveform on the screen.
13.8.2 Setting up RESP Measurement
For RESP monitoring, it is not necessary for additional electrodes, however, it is very important
to attach the electrodes to the correct positions.
Some patients, due to their clinical condition, expand their chest laterally, causing a negative
intrathoracic pressure. In these cases it is better to place the two RESP electrodes laterally in the
right axillary and left lateral chest areas at the maximum point of breathing movement to
optimize the respiratory waveform.
NOTE:
The RESP monitoring is not recommended to be used on patients who are very active, as
this can cause false alarms.
Checklist for RESP Monitoring
1. Prepare the patient's skin prior to placing the electrodes.
2. Attach snap or clip to the electrodes and attach the electrodes to the patient as described
below.
3. Switch on the monitor.
