What is a defibrillator?
Q: What is a defibrillator?
A: A defibrillator is a machine that is used when ventricular fibrillation happens in the heart of a human.
Q: What is the purpose of a defibrillator?
A: The purpose of a defibrillator is to save a person's life by correcting ventricular fibrillation.
Q: What happens during ventricular fibrillation?
A: During ventricular fibrillation, many different cells in the heart begin to act as pacemaker cells, causing confusion and an inability to move blood around the body.
Q: How does a defibrillator work?
A: A defibrillator sends a high energy pulse from the top-right of the heart to the bottom-middle of the heart, causing the whole heart to stop all activity. This allows the heart's normal pacemaker to restart normal beating.
Q: Is defibrillation always successful?
A: No, defibrillation does not always work.
Q: Why is defibrillation important?
A: Defibrillation is important because it can save a person's life when experiencing ventricular fibrillation, which can lead to cardiac arrest and death.
Q: What is the main cause of ventricular fibrillation?
A: The main cause of ventricular fibrillation is when many different cells in the heart act as pacemaker cells, causing confusion and an inability to move blood around the body.
