AED or Automated external defibrillator is a portable, BATTERY-OPERATED DEVICE THAT IS USED TO MEASURE THE RHYTHM OF THE HEART DURING CARDIAC ARRESTS AND PROVIDE SHOCKS IF NECESSARY to restore the normal pace and functioning of the heart.

What is the importance of learning how to use AED?

Cardiac arrests are very sudden, without proper emergency response in the initial 10-12 minutes the patient may suffer a variety of conditions like stroke and even death. In India, every 1 in 10 person dies from cardiac arrests and nearly 85% of the cardiac arrests happen outside the hospital which is a scary statistic. that’s why learning the measures to get help or help someone during cardiac arrests become important.

What is fibrillation and defibrillation?

Before learning what defibrillation is we should understand fibrillation, During fibrillation, the heart’s two small upper chambers don’t beat the way they should. Instead of beating in a normal pattern the atria beat irregularly and too fast . this causes the heart muscles to twitch due to this blood clots will be formed which increases the risk of having the stroke

Now, defibrillation is a process in which shock will be passed to the heart to restore this irregular beating to the right speed.

  • How does an AED work?
  • cardiac arrests the electro pads will be connected to the patient’s body, AED reads the electric signals and understands the rhythm of the heart. if the rhythm is upset it will understand how many current needs to be supplied to make it right. After providing the shock once, it measures the rhythm again, if it is still upset it understands again how much amount of current needs to supply if the rhythm had gone back to normal it instructs us not to give shock again. It works in a feedback loop where it constantly monitors heart and understands the required measures.
  • Precautions to be taken while using AED.
  1. Avoid touching the patient after connecting the electrodes to get proper readings.
  2. Avoid touching the patient while providing shock.
  3. The electric paddles used in the procedure should not be placed
