yes you cannot shock a patient unless there heart rhythm is in either v tach or v fib
The two rhythms an AED will only shock are Ventricular Fibrillation (V-Fib) and Ventricular Tachycardia (V-Tach).
when the AED tells you to do so
when the AED tells you to do so
when the AED tells you to do so
only the time needed to attach an AED and for it to deliver a shock
The number of shocks will depend on the results of the AED analyzing the patient. It will vary on the situation and protocols set up in the AED. You will not be able to shock a patient until determined by the AED a shockable rhythm exists.
The AED could pick up the heart rhythm of the person touching the victim and not shock when a shock is required.
An automated external defibrillator (AED) should be used when the patient has cardiac arrest. This is when the heart suddenly stops beating; the AED will distribute a shock to the heart to try to get it beating again.
Child AED pads may not deliver enough energy, so they are not appropriate to use for an adult.
The only way a conscious person can be shocked by an AED is if they are touching the person that is being shocked, or touching metal that the person being shocked is touching, or standing in a puddle of water that the person being shocked is in. AED's are designed to only shock unconscious and pulse less victims, they have built in sensors that analyze heart rhythms and only shock if no rhythms are present. They cannot distinguish the difference between the heart's electrical rhythms and the electrical signals that your brain sends your muscles. So if a person is breathing, thinking, or their heart is beating, then an AED attached to them will not function. However, the electricity of an AED can be conducted from a patient being shocked through direct contact, water, or metal to an unintentional second person. - Courtney EMT/CPR Instructor
AED is an acronym that stands for Automated External Defibrillator. It is used to stop the heart's motion via electric shock, effectively hitting the hearts "reset" button. The heart then, hopefully restarts with normal activity. An AED cannot be used when a heart is in asystole, a state of no electrical activity. Also, an AED cannot be used in a moving vehical as that affects the analysis.
There is no shockable rhythm the AED can shock for.
