Few people think they are in an emergency situation and need to save a life. Most people imagine that emergency situations only happen in hospitals or dangerous places. But in reality everyone needs to consider what to do during an emergency, because 88% of cardiac arrests will occur in the home. Cardiopulmonary resuscitation, or CPR, is a vital skill that can save people who are unconscious or not breathing due to cardiac arrest or other injuries. Anyone can learn how to perform CPR by learning the six basic phases along with the different steps in each phase. The first phase begins when you notice a person who may need CPR. It is necessary to immediately assess the situation around the potentially injured or ill person. Check whether the scene is safe from potential hazards such as car traffic, fire or water. If possible, your first priority is to remove yourself and the person from danger. Then, check if the person is responsive. Test it by patting him on the back and asking out loud, “Are you okay?” If the person is unresponsive, they may need CPR. The second step involves calling 911, or another available emergency number, as soon as possible. So try purchasing an AED and a first aid kit. If there are one or more people nearby, delegate these tasks to them so you can focus on performing CPR. If there is no one to delegate these tasks to, you must perform them yourself before starting CPR. Unless you call 911 and get an AED, the person is unlikely to survive using CPR alone. CPR is intended to maintain a person's blood and oxygen flow while waiting for trained personnel to arrive. The third phase requires preparation for the administrative process… halfway through the document… which begins with thirty chest compressions. Phase six is ​​simply continuing CPR and/or AED use until success or failure. If a doctor arrives, entrust the situation to him. If medics have not yet arrived, continue CPR and/or AED use until they arrive or until you are too exhausted to continue. If another CRP certified person is available, end the session with that person. One of the most common mistakes a person makes during CPR is giving priority to mouth-to-mouth resuscitation over chest compressions. It has been proven that chest compressions can support a person without breathing. Breaths can wait. Even if you don't want to give mouth-to-mouth resuscitation during CPR, it's better to give chest compressions than to do nothing. We hope this simple 1, 2, 3 process has made the use of CPR and AED very clear to you.
