Semi Automatic Defibrillators

A semi-automatic AED analyzes a person’s heart rhythm and indicates if a shock is needed. The user then presses a button to deliver the shock, giving them full control. These devices are safe for anyone to use, including untrained bystanders, because they will only allow a shock when it is medically appropriate.

How They Work

• Analysis: The AED checks the heart rhythm to determine if a shock is required.

• Guidance: Clear audio and/or visual prompts tell the user what to do.

• Shock Delivery: The user must press a button to deliver the shock; the AED will not shock automatically.

• Safety: Built-in safeguards prevent unnecessary shocks and warn bystanders not to touch the patient during delivery.
