When organs and tissues don’t receive enough oxygen, they can begin to die. While breathing enriches the blood with oxygen, it’s the beating of the heart that delivers this oxygen throughout the body. Rescue breaths, along with chest compressions, are given during cardiopulmonary resuscitation (CPR). This helps you temporarily breathe for the other person. You can perform rescue breaths on someone who isn’t breathing. Continue to do this for no more than 10 seconds.Check for the following signs of breathing:.Place your ear directly above the person’s mouth while looking down at their body.To determine if a person is breathing normally, take these steps: That’s why it’s crucial to determine whether someone is breathing or not. While tilting their head, use two fingers from your other hand to carefully raise their chin.īreathing supplies the body with life-giving oxygen.Place one hand on the person’s forehead.You can help open someone’s airway by doing the following: A = AirwayĪ blocked airway can hamper a person’s ability to breathe. The AED will reanalyze every 2 minutes and prompt for a shock if needed.The ABCs of first aid consist of three different components.Continue cycles of 30:2 until you see signs of life. As soon as the shock has been delivered, give 30 chest compressions followed by 2 breaths.If no shock is advised, give CPR if the patient is not moving and not breathing.Push the shock button when the AED tells you to. If the AED says, “Shock advised, charging…,” shout, “Clear” and make sure no one is touching the patient.Do not touch the patient while the AED analyzes. Make sure pads are pressed down firmly.Place the other pad on the patient’s lower left ribs below the armpit. Place one pad on the patient’s upper right chest above the nipple.If there is excessive hair, you may need to shave it off.
PLEASE NOTE: Never remove the pads from the patient or turn the machine off. And remove medication patches found on the patient’s chest with a gloved hand. Slightly adjust pad placement so as not to directly cover the area if the patient has an obvious bump or scar for a pacemaker.Also, remove the person from a metal surface, if possible. Rain, snow, or a damp surface are not a concern. Remove a patient from standing water, such as a puddle, before AED use.Rescuers should begin chest compressions as soon as possible and use the AED as soon as it is available and ready.
Early defibrillation increases survival rates to greater than 50%. Few people are resuscitated after 10 minutes of no circulation, no breathing, and no CPR. This is called asystole.Įach minute that defibrillation is delayed, the chance of survival is reduced by 10 percent. Eventually, all electrical activity stops. The more time that passes without circulation and oxygen, the more damage is done to the heart muscle. The AED forcefully shocks the heart to stop the chaotic or excessively fast electrical activity so that the heart can reorganize and return to its normal organized electrical activity, pumping and circulating blood with oxygen. When an AED recognizes one of these two rhythms, it will allow a shock to be given. In either rhythm, the heart is not beating normally and there is no circulation of blood. Ventricular tachycardia is an organized pattern of electrical activity where it is so fast that the ventricles are basically quivering. A lack of oxygen can also cause the heart to beat faster and faster in an attempt to circulate more blood, causing the heart to beat so fast that ventricular tachycardia occurs. When a person’s heart is not getting enough oxygen, cells in different areas of the heart begin to fire electrical impulses on their own in an attempt to produce more circulation, which causes the heart to go into ventricular fibrillation, chaotic electrical activity where cells are firing all throughout the heart with no organized pattern. An AED will recognize two deadly heart rhythms - ventricular fibrillation and ventricular tachycardia.
