What does "semiautomatic" mean in the context of an AED?

It requires no operator input
The operator must push down to shock after a prompt
The AED analyzes but does not notify the operator
It will automatically administer CPR

The correct answer is: The operator must push down to shock after a prompt

In the context of an Automated External Defibrillator (AED), the term "semiautomatic" refers to a device that requires the operator to actively engage with it before delivering a shock. When the AED analyzes the heart rhythm and determines that a shock is necessary, it will prompt the operator to administer the shock by pressing a button or a switch. This design requires a level of human interaction, ensuring that the operator is aware and in control of the administration of the shock. The requirement for operator intervention is a key distinguishing feature of semiautomatic devices as it promotes safety and allows the rescuer to assess the situation before delivering a shock, preventing unintentional shocks if conditions change or if the patient is moved. This contrasts significantly with fully automatic AEDs, which deliver shocks without any need for operator input, making it essential for users to be familiar with the device they are using.
