How to act if a person is having a heart attack (first aid)

First aid for a heart attack: what to do and how should we act if a close person is suffering from cardiac arrest? We reveal it to you.

If we meet someone who may be having a heart attack, the first thing we should do is ask someone to call the emergency medical service or we should do it ourselves if we are alone. Then we must begin first aid

If possible try to get the affected person to sit down and try to be as calm as possible. We must also ask you if you have any medication that your doctor has prescribed for chest pain (such as nitroglycerin) and help you take it. If you have very tight clothes you have to loosen them.

In the event that the affected person is unconscious (that is, does not react to stimuli), without breathing and without a pulse, and after contacting the medical emergency, we must perform Cardio Pulmonary Resuscitation (CPR). Some steps of the procedure vary depending on whether they are children up to 8 years old, or people 9 years of age or older.

Here are the steps recommended:

  • Try to get the person to react by shaking them gently or patting them gently. If you are old enough to answer, we ask you out loud if you are okay.
  • If there is no answer ask someone to call the emergency. If you are alone, call the emergency, but if it is a child under 8 years of age, it is appropriate not to leave him alone before performing CPR for two minutes.
  • Carefully lay the affected person face up.
  • If an automated external defibrillator or AED is on site, place the paddles on the patient’s chest. This device takes measurements of vital signs at the moment and, if necessary, calculates the shock to be applied. Always follow the instructions of the device.
  • If this defibrillator is not available, start the CPR maneuver (Cardiopulmonary Resuscitation).

How to do cardiac compressions in children from 1 to 8 years old:

To do chest compressions on a child under 9 years of age:

  1. Put the base of one hand located on the sternum (it would be just below the nipples) but we must NOT do it on the end of the sternum to avoid damage.
  2. Leave the other hand resting on the child’s forehead, so that this allows the head to be tilted backwards
  3. With the hand that is resting on the chest, you have to compress the chest between 1/3 and 1/2 of its depth.
  4. 30 compressions are performed as above. Each compression should be strong, fast and without pause, but the chest should be allowed to fully rise after each compression. These compressions should be delivered quickly and forcefully without pause.

How to do cardiac compressions in children over 9 years old and adults:

  1. The base of one hand is located where the sternum is located, this is right in the middle of the nipples and the second hand is placed on the first, carrying our body directly on the hands.
  2. 30 compressions are applied hard and fast, so that about 5 centimeters are pressed into the chest. Quickly count the 30 compressions.
  3. Perform mouth-to-mouth resuscitation.

If the person or the child does not react or does not recover their breath after performing the thirty compressions, we will apply mouth-to-mouth resuscitation as follows:

  1. Lift the chin with one hand and gently push the head back, placing the other hand on the forehead. This will clear the airways.
  2. Detect if there is breathing by placing our ear and then our cheek next to the nose and mouth, and also observe the presence of movement in the chest.
  3. If they are not breathing, place your mouth firmly over the person’s and pinch their nose with your fingers, while keeping your head tilted and your chin up.
  4. Perform 2 mouth-to-mouth insufflations. Each lasting one second, we should see the chest rise.
  5. If there is no improvement, perform the 30 compressions again (as indicated according to the person’s age) and then the two inflations, repeating the cycle until the arrival of medical help.

Today it is easy to find a place to take these courses, in many cases for free, do not stop doing it as soon as you can to be prepared in case of such a situation.
