Today, cfiva.org would like to introduce to you How Does CPR Actually Work?. Following along are instructions in the video below:
Lifeguard pulls a drowning child from the ocean. An old man collapses in the street street a woman faints. Not breathing.
These are all situations. That might call for cpr stands for cardiopulmonary. Resuscitation.
And the american heart association. Aha. Describes.
Cpr. As an emergency lifesaving procedure performed when the heart stops beating which is a condition known as cardiac arrest. Cpr is typically done until an automated external defibrillator aed can be applied and or trained medical professionals can provide assistance.
There are some things you should do before you perform cpr. One of them is to make sure you and the person who might need cpr are in a safe area. You should also check to see if the person really needs help if the person is an adult try asking if he or she is okay in a loud voice you can also tap or shake the person.
If the person does not respond call 911. There are two common versions of cpr the simplest one being called hands only cpr and involves performing chest compressions after calling. 911.
You dont need special training to do hands. Only cpr and the american red cross describes how to perform this type of cpr. 1.
Kneel. Beside the person who needs help 2 place the heel of one hand on the center of the chest. 3.
Place the heel of the other hand on top of the first hand then lace your fingers together 4 position your body. So that your shoulders are directly over your hands. And keep your arms straight.
5. Push hard push fast use your body weight to help you administer compressions that are at least 2 inches.
Deep and delivered at a rate of at least 100 compressions per minute just be sure to let the chest rise completely between compressions. 6. Keep pushing continue hands.
Only cpr until you see obvious signs of life like breathing. Another trained responder or ems professional can take over youre too exhausted to continue an aed becomes available or the scene becomes unsafe. How do chest compressions help keep a person alive when the heart stops beating blood flow also stops and this can be fatal.
Because blood is how oxygen gets transported to the brain and other parts of the body. The mayo clinic explains it this way when the heart stops the lack of oxygenated blood can cause brain damage in only a few minutes a person may die within eight to 10 minutes. According to the verywell health website compressing the chest moves blood through the brain keeping it alive.
Until. The heart can get started. Again.
The second common version of cpr. Is called traditional cpr. It also involves performing chest compressions.
But adds two other actions that require some training opening the airway and rescue breathing according to one of its fact sheets the aha recommends cpr with compressions and breaths for infants and children and victims of drowning drug overdose. Or people who collapse due to breathing problems. The purpose of opening.
The airway and giving rescue breaths is to provide air to someone who is not breathing or is having difficulty breathing. It is a form of artificial respiration that helps to keep the body and brain from dying due to lack of oxygen while many health professionals agree about the importance of chest compressions. They disagree about the value of rescue.
Breaths verywell health. Describes rescue breathing as one of the most controversial steps in cpr it adds that the debate is ongoing about how much is enough or too. Much and whether its even necessary the american red cross provides some instructions about what to do before performing traditional cpr on an adult.
It advises to check the scene and the person next you should open the airway to do this the american red cross instructs you to tilt. The head back slightly to lift the chin of the person. While he or she is lying on his or her back after opening the airway listen for breathing for about 10 seconds.
And begin cpr. If you dont hear any breathing.
In addition. The american red cross lists the following steps to perform traditional cpr on adults 1 push hard push fast place your hands. One on top of the other in the middle of the chest use your body weight to help you administer compressions that are at least 2 inches.
Deep and delivered at a rate of at least 100 compressions per minute. 2. Deliver rescue breaths with the persons head tilted back slightly and the chin lifted pinch the nose shut and place your mouth over the persons mouth to make a complete seal blow into the persons mouth to make the chest rise.
Deliver two rescue breaths then continue compressions note. If the chest does not rise with the initial rescue breath re tilt. The head before delivering the second breath.
If the chest doesnt rise with the second breath. The person may be choking. After each subsequent set of 30 chest compressions and before attempting breaths look for an object.
And if seen remove it. 3. Continue cpr steps keep performing cycles of chest compressions.
And breathing. Until the person exhibits signs of life such as breathing an aed becomes available or ems or a trained medical responder arrives on scene note. The mayo clinic states that thirty chest compressions followed by two rescue.
Breaths is considered one cycle. Other sources such as the aha also recommend using chest compressions and mouth to mouth breathing. At a ratio of 30 2.
Compressions to breaths in traditional cpr. There are some differences in the steps you take to perform cpr on a child or an infant for example. The procedure for checking if the child or infant really needs help is not the same as the one used for an adult tap or shake a child more gently than you would an adult.
However do not shake an infant. The national cpr association warns that you should never shake an infant as this may cause brain damage instead the american red cross advises you to flick the bottom of the foot to elicit a response. The american red cross also offers different advice about when to call 911.
You can ask a bystander to call 911. Then administer approximately 2 minutes of care however if youre alone with the child or infant administer 2 minutes of care then call 911 the care involves the following steps 1 open the airway with the child lying on his or her back tilt.

According to baylor college of medicine. Professor.
William l. Winters. Two anesthesiologists at johns hopkins hospital.
Peter safar. And james elam. Came up with an emergency ventilation technique.
That involved tipping the victims head back and pulling the jaw forward in order to clear the air passage and then blowing air into the victims lungs through a mouth to mouth connection. The aha states that dr. Elam and dr.
Safar were able to prove that mouth to mouth resuscitation. Is an effective lifesaving method in 1956 and they and another doctor named archer gordon promoted its use in a jama article published in 1960. An electrical engineer named william b.
Kouwenhoven. And his colleagues james jude and guy knickerbocker presented the concept of closed. Chest.
Cardiac massage. Which was a method of restoring circulation in a heart. Attack victim by pushing down rhythmically on the sternum winters.
States that the combination of kouwenhovens technique with safars ventilation technique evolved into the basic method of cpr in 1960. The aha began a program that became the forerunner of cpr training for the general public. Hands.
Only cpr is a more recent development winters. States. It emerged from research conducted at the university of arizona sarver heart center in the mid 1990s.
This research led to the discovery that continual chest presses kept blood circulating in adult victims of cardiac arrest better than conventional cpr techniques hands only cpr for adults was adopted by the aha in 2008 would you perform cpr on someone who needs it why or why not let us know in the comments also be sure to check out our other video.
