3.2 Attaching Electrodes to the Patient
WARNING
1. Make sure that all electrodes are connected to the patient correctly before operation.
2. Ensure that the conductive parts of electrodes and associated connectors, including
neutral electrodes, do not contact the earth or any other conducting objects.
NOTE: The quality of the ECG waveform will be affected by the contact resistance
between the patient and the electrode. Proper skin preparation (abrasion if necessary),
proper electrodes, and patient cables in a fixed position are essential for good signal
quality.
The identifiers and color codes of electrode connectors comply with IEC/EN requirements.
Avoid incorrect connections; the identifiers and color codes are specified in Table 3-1.
Moreover, the equivalent codes according to AHA requirements are also given in Table
3-1.
