CPR (cardiopulmonary resuscitation) is a life-saving technique that is used to restore blood flow and breathing to someone who has suffered cardiac arrest. The procedure is typically performed on a person who is unconscious and not breathing, or who is breathing in an abnormal and ineffective manner.
CPR is a combination of chest compressions and rescue breathing. Chest compressions help to circulate oxygen-rich blood to the brain and vital organs, while rescue breathing provides the person with oxygen. By performing CPR, a rescuer can help to keep the person alive until emergency medical services arrive and can provide more advanced care.
When someone suffers cardiac arrest, time is of the essence. The longer a person goes without CPR and advanced medical care, the less likely they are to survive. In fact, for every minute that passes without CPR and defibrillation, the chance of survival decreases by about 10%. This is why it's important to act quickly when someone is in cardiac arrest and to call emergency medical services immediately.
It's also important to note that when a person's heart stops, the brain is at risk of serious damage due to lack of oxygen. This is why it's important to initiate CPR as soon as possible to try to prevent brain damage.
In summary, CPR is a life-saving technique that can help to restore blood flow and breathing to someone who has suffered cardiac arrest. It's important to act quickly when someone is in cardiac arrest, as the longer a person goes without CPR and advanced medical care, the less likely they are to survive.
