How are AED defibrillators used?

 

A defibrillator is a device that delivers electrical shocks to the heart through the chest wallThanks to the sensors it has, this device is capable of analyzing the heart rhythm, determining when it is necessary to proceed with the discharge and knowing at what intensity level it should be performed.

The main function of this device is restore the heart rhythm of a patient who has just suffered a heart attack. In these situations, the time factor is decisive, so It is advisable that not only health professionals have one, but also that companies also have these elements to save lives.

 

How should we use a defibrillator?

 

In this article we want to explain how a defibrillator works and how it should be used in an emergency.

The first step is to start the defibrillator. Some will do it automatically when you open the lid, in others you must press the power button. If someone is performing Basic Life Support when arriving with the defibrillator to the victim, compressions should be continued while the electrodes are placed on the chest.

We will place the patches on the victim's bare chest, their position is normally labeled: One, on the right side of the thorax under the clavicle, next to the sternum. The other, on the left side, under the chest, in the rib area. Once placed, the defibrillator will analyze the heart rhythm, during this process it is very important that no one touches the victim.

If the defibrillator tells us that we need to deliver a shock, we'll again make sure no one is touching the victim, and hit the shock button. Immediately after, we will start Basic Life Support. If the defibrillator tells us NOT to deliver a shock, we will immediately start Basic Life Support again. Every 2 minutes, the defibrillator will make us stop Basic Life Support to reanalyze the rhythm, and discharge or not (as indicated by the device).

 

post shock CPR

 

It is essential that we continue with resuscitation techniques until: the victim breathes normally, opens his eyes or moves, a health professional tells us.

To perform correct CPR, the following steps must be followed:

  • The first step must be carried out by placing the base of the palms of your hands on the center of the victim's chest. With one hand over the other, keep your elbows well stretched and go moving from top to bottom. You should use the full weight of your body, pressing to compress the chest, about two inches. Repeat this movement firmly at a rate of 100 to 120 compressions per minute.
  • After completing that process, comes the second. Normally, if you are already trained in CPR technique, after the first 30 compressions, open the airway. To do this, you must tilt the person's head and lift their chin. Start by placing your palm on his forehead and gently tilt his head back. then with your other handlift your chin forward. This way you prevent the tongue from impeding the passage of air to the lungs.
  • Finally, in rescue breathing you can provide oxygen to the patient through the mouth or nose. In the latter, always in the event that the area of ​​the mouth is injured and cannot be acted upon. If this circumstance does not arise, squeeze your nostrils and start mouth to mouth, joining yours with his. After the first breath, see if the chest rises for a second. If that doesn't happen, he repeats the airway-opening maneuver and tries again to give her oxygen.

You must repeat that cycle of compression-opening-breathing. That is, 30 compressions plus two air contributions. So until the person regains consciousness or moves a muscle. Or until you have an automated external defibrillator to apply as directed.
