Note the following when using defibrillator electrodes to ensure safety and effectiveness:
1. Place the device in the correct position
• Adults: The anterolateral position is adopted by default, that is, one piece is attached below the right clavicle (right margin of the sternum) and the other is attached to the fifth intercostal space (apex of the heart) on the left midaxillary line.
• Children/infants: Anterior and posterior positions (one on chest, one on back) or child-specific electrodes may be required.
• Avoid implanted devices: If the patient has a pacemaker, ICD, etc., the electrode should be at least 8 cm away from the device to avoid interference.
2. Skin preparation
• Clean and dry: remove sweat, drugs or foreign matter from the chest and wipe it with a dry cloth; If too much hair needs to be shaved, make sure the electrodes fit.
• Avoid alcohol/flammables: do not use alcohol to clean, to prevent sparks from burning; Remove objects containing metal (necklaces, ointment patches, etc.).
3. Check the electrode status
• Expiration date and packaging: Before use, confirm that it is not expired, the packaging is not damaged, and the conductive gel is not dry.
• Single-use: It is prohibited to reuse, to prevent cross infection or decrease in electrical conductivity.
4. Environmental and operational safety
• Avoid contact with patients: Ensure that no one touches patients and beds before discharge to prevent electric shock.
• Energy selection: Select the appropriate energy according to the device instructions (adults usually start at 120-200 J, children adjust according to body weight).
Avoid wet/combustible environments: Ensure that there is no water or oxygen leakage in the operating area to reduce the risk of fire.
5. Special patient handling
• Drug patches: If there are patches such as nitroglycerin on the chest, remove them immediately and thoroughly clean the skin.
• Burn treatment: Check the skin after defibrillation. If there is redness or burn, treat it as burn and record it.
6. Operation specifications
Training and procedures: Operators are professionally trained and strictly follow first aid guidelines (e.g. AHA/ERC standards).
• Device self-test: Verify that the defibrillator is functioning properly and the electrodes are connected correctly before use.
7. For children and infants
• Size adaptation: Children should use pediatric electrodes (or pediatric mode) to avoid adult electrodes covering too much area.
8. Handle the fault after the operation
• Recording information: recording electrode position, energy selection and patient reaction for subsequent medical reference.
• Replacement tips: If continuous monitoring is required, replace the new electrode as needed to avoid skin damage caused by long-term use.
