EMT in person class- AED
Today in EMT class we learned how to use the AED (Automated External Defibrillator). This is a portable device that is used to send electric shock signals through a patient’s heart during cardiac arrest. The machine analyzes heart rhythm and delivers shock, when appropriate, to restore a regular heart rate.
Going into the class, I had been expecting to learn how to use a defibrillator: the machine often seen in movies. I had been envisioning a doctor holding onto two paddles and screaming “clear!” shortly before delivering a dramatic shock to their patient. To my surprise, this machine mainly does it all on its own. The only thing I was responsible for was the placement of the two pads and making sure that no one is touching the patient while the machine administers a shock.
This is the process of how to use an AED:
- If you witness a patient going into cardiac arrest, as always check to make sure everything is safe before entering the scene
- Check for a response (first verbal, then tap their shoulders, then give their shoulders a pinch to check for painful stimuli)
- Check for a pulse and chest rise
- Start giving CPR prior to defibrillation while you wait for application of defibrillation pads (5 cycles of 30 chest compressions to 2 breaths through a bag valve mask connected to supplemental oxygen)
- The other partner should place AED pads (one pad placed underneath the patient’s right collarbone and the second pad placed on the left chest underneath the armpit)
- After 5 cycles of CPR, turn on the AED and have it do a rhythm check. It will analyze the heartbeat and tell you if you need to defibrillate or continue CPR.
- If you are going to defibrillate, you must make sure that the scene is clear around the patient (my instructor recommended making a sweeping movement around the patient while aggressively yelling “stay clear!”)
- After you defibrillate, resume CPR and check rhythm after another 5 cycles
- Check rhythm again (continue this until the patient is no longer in cardiac arrest)
