 Well place the electrodes: squeeze the chest suction bulb to make the lower edge of the
metal electrode tightly connected with the skin. Loosen the bulb to make the electrode
adsorbed on the patient's skin;
 Ensure that the ECG machine and its cable, electrodes and lead wires are firmly
connected.
5.3.2.2 Limb Clamp
The limb clamp is composed of the clamp and metal electrode. There is a connection hole on
the metal electrode, which is used to connect the lead wire of Φ4.0 mm connector.

Placing Limb Clamps
Limb electrodes should be placed above the forearm wrist joint and the calf ankle joint medial to
make them closely contact with skin, bypassing the bones.
 Check the electrodes to verify that they are clean,
 The four limb electrodes are respectively connected with the corresponding lead wire.
Straighten out the lead wires, and avoid twisting,
 Roll up sleeves and trousers to expose electrode sites.
 Prepare the skin,
 Apply a thin layer of conductive cream on the surface of electrode sites;
 Apply a thin layer of conductive cream on metal electrodes,
 Well place the electrodes: clamp the prepared sites by limb clamps;
