Non-rechargeable semi-automatic external defibrillator

Semi-automatic external defibrillators use compatible electrodes to connect the patient and automatically analyse the victim's ECG rhythm to determine whether an electrical shock should be delivered, alerting the rescuer when a shockable rhythm is detected and instructing them to press the shock button. These devices are indicated for use on patients with suspected sudden cardiac arrest who are unconscious, unresponsive and not breathing or breathing abnormally.
