Learning CPR can be done through books, videos, websites, or in-person classes. In-person classes are often preferred as they provide hands-on instruction and certification. CPR involves rescue breathing and chest compressions to keep air and oxygen-rich blood circulating in a person’s body. It is important to know when to use CPR and when to stop. Refresher courses are recommended every two years.
There are many ways to learn CPR or cardiopulmonary resuscitation. There are books, videos, websites and even interactive demonstrations from which a person can learn this life-saving technique. However, many people believe that the best way to learn CPR is in the classroom where students can watch a demonstration and receive hands-on instruction from a teacher.
If a person decides to learn CPR online, in a class, or from a video, they learn a life-saving technique. When someone performs this technique, it rescues the breath in a person’s mouth and compresses their chest. The purpose of this technique is to keep air circulating through the victim’s body when he cannot breathe on his own and to keep oxygen-rich blood flowing in a person’s body when his heart stops beating on its own.
When someone learns CPR, they discover how to do rescue breathing by placing their mouth over the victim’s open mouth and blowing air into the victim’s lungs. Usually, after taking two breaths in this way, the rescuer places one hand over the other and presses repeatedly on the victim’s chest. Thirty chest compressions are given, and then the rescuer follows by providing two additional breaths of air. This breathing cycle continues until emergency medical help such as an ambulance or a doctor arrives. It is critical to maintain the cycle of breathing and compressions, as the brain cannot survive a prolonged period without oxygen.
Another thing a person should learn from a CPR class, book, or video is when to use it and when to stop. This technique should be performed whenever a person stops breathing and their heart stops. This may be necessary if a person has had a heart attack or stroke, an object has blocked their airway, nearly drowned, or suffered a back or neck injury. It may also be necessary if a person gets a severe electrical shock or has a severe allergic reaction.
In-person CPR classes usually end in certification for the person who has just learned the technique. It is often suggested that the person take a refresher course every two years. While books and websites can be good for learning CPR, the problem with this type of instruction is that there is no one to tell the student if they are doing something incorrectly. Also, there is usually no certification with this type of learning. However, deciding to learn CPR from a book or online may be better than not receiving any instruction.
