Final answer:
The question incorrectly mentions emergency 'panic buttons' but likely refers to Automated External Defibrillators (AEDs), which are life-saving devices found in many public places to assist during a cardiac attack.
Step-by-step explanation:
The question seems to be referring not to emergency "panic buttons" but to Automated External Defibrillators (AEDs), which are crucial life-saving devices used during a cardiac event.
AEDs are usually located in many public places and are designed to provide immediate assistance before emergency medical services arrive. These devices often include verbal instructions that guide a bystander through the process of administering the defibrillation.
It's hard to specify exactly how many AEDs are present in any given location without further context, as locations vary widely. However, they are commonly found in areas such as schools, gyms, airports, malls, and community centers.
They are strategically placed for quick access, and signs are often in place to aid in locating them rapidly during an emergency.
