Explanation:

First Question: What do AEDs analyze?

AEDs (Automated External Defibrillators) are medical devices used in cases of cardiac arrest. Their primary function is to analyze the heart's electrical rhythm to determine if a shock is needed. Blood pressure is measured by devices like sphygmomanometers, oxygen levels by pulse oximeters, and pulse can be checked manually or with other devices, not AEDs.

When someone collapses, the first step in emergency response is to ensure the scene is safe (for both the victim and responder) and then start CPR if needed. Requesting everyone to leave is impractical, waiting for responders without acting delays care, and moving the person can cause harm.

Answer:

a. The heart’s rhythm
