CPR is an emergency procedure that involves the Circulatory and Respiratory systems, using chest compressions between the T4 and T9 vertebrae to sustain blood flow and oxygen delivery until the heart recovers or medical help arrives.
Cardiopulmonary resuscitation, or CPR, is a procedure that involves the A. Circulatory and B. Respiratory systems. This emergency technique is used if the heart of a patient should stop. By applying pressure on the sternum between the lines at T4 and T9, it is possible to manually compress the blood within the heart to push it into the pulmonary and systemic circuits, which is essential for maintaining blood flow to the brain to prevent irreversible damage. The application of chest compressions at a rate of 100 compressions per minute can sustain the flow of blood until the heart resumes beating or the patient is declared dead.
In conclusion, CPR is an emergency lifesaving procedure that significantly relies on the correct application of chest compressions to support the circulatory and respiratory functions until professional medical help can be provided or the heart regains its rhythm.
