  • Defibrillators
    • Defibrillation- restores a regular heart rhythm by giving someone an electric shock through the chest to the heart.
    • 1. Two paddles charged from high-voltage supply.
    • 2. Placed firmly on patient's chest to ensure good electrical contact.
    • 3. Electric charge passed through the patient to make their heart contract.
    • 4. Great care taken to ensure that the operator doesn't receive an electric shock.
    • If switched on for 5 ms (0.005s), power can be calculated from:               Power = energy/time = 400/0.005 = 80,000W.
