Answer :
Final answer:
CPR (Cardiopulmonary Resuscitation) is an emergency technique used when a person's heart stops, manually compressing the heart to circulate blood to vital organs like the brain. Incorrect application can cause serious harm, thus proper training is crucial. CPR is often used alongside automated external defibrillators (AEDs).
Explanation:
Cardiopulmonary resuscitation, otherwise known as CPR, is an emergency life-saving procedure that's applied when the heart of a patient stops. It involves manually compressing the blood within the heart by applying pressure on the sternum, between the line at T4 and T9. This action is intended to push some of the blood within the heart into the pulmonary and systemic circuits, maintaining the flow of blood, particularly to the brain where loss of blood flow can lead to irreversible neuronal damage and death within minutes.
Proper execution of CPR requires thoroughly trained individuals as incorrect or overzealous application can lead to bodily harm such as broken ribs, and severe damage even possibly driving the xiphoid process into the liver. Thus, many hospitals, colleges, non-profit organizations, and commercial companies offer CPR training and certification courses.
Although CPR is a standalone life-saving technique, it is commonly used in conjunction with automated external defibrillators (AEDs) to treat cardiac arrest patients.
