What medical procedure is used when a person’s heart or lungs have stopped working?

Explanation:
When the heart or lungs have stopped, the goal is to keep blood circulating and oxygen reaching vital organs. CPR achieves this by combining chest compressions to pump blood through the body with rescue breaths to bring oxygen into the lungs. This action buys time and maintains circulation until professional help can take over. The other options target airway problems rather than restarting the heart or supporting circulation—abdominal thrusts and back blows relieve choking, while an obstructed airway describes a condition, not a procedure. In this scenario, starting CPR is the approach that directly addresses halted heart and lung function.
