What is the procedure combining chest compressions and breaths to provide oxygen to tissues when the heart is unable to do so called?

The procedure that combines chest compressions and breaths to provide oxygen to tissues when the heart is unable to do so is known as cardio-pulmonary resuscitation, or CPR. This lifesaving technique is essential in situations where a person's heart has stopped beating effectively or at all, as it helps to maintain blood flow and oxygenation to vital organs, particularly the brain.

When performing CPR, chest compressions are critical because they mimic the pumping action of the heart, facilitating the circulation of blood throughout the body. The addition of rescue breaths helps to deliver oxygen directly into the lungs, which is then absorbed into the bloodstream and transported to the tissues. This combination of mechanical support for circulation and artificial respiration is vital in preventing tissue damage and increasing the chances of survival until advanced medical help arrives or until the heart starts working effectively again.

Other options presented, such as rescue breathing, focus solely on providing breaths without incorporating chest compressions, making them less effective in emergency cardiac situations. Cardiac arrest protocol refers to the overall guidelines for managing a cardiac arrest but does not specifically name the procedure. Finally, advanced life support encompasses a range of advanced medical interventions conducted by trained healthcare professionals, which comes into play after basic life support measures like CPR have been administered.
