What is CPR?

Cardiopulmonary resuscitation (CPR) is a critical lifesaving technique used in emergencies when a person's heartbeat and breathing have stopped. It involves chest compressions and rescue breaths, which help maintain blood flow to the brain and other vital organs until professional medical help can arrive or until the individual resumes normal breathing and heartbeat. The timely application of CPR can significantly increase the chances of survival in cases of cardiac arrest or near-drowning, making it an essential skill for anyone, especially surf lifeguards.

Other choices describe different concepts: one suggests a method for water-safe swimming which, while important for preventing drowning, does not address life support in emergencies. Another refers to a type of first aid kit, which is crucial for treating injuries but not directly related to the immediate response needed for cardiac arrest. The last option caters to general beach safety protocols that ensure environmental and visitor safety but do not encompass the lifesaving aspects of CPR. Thus, the correct answer emphasizes the specific, life-saving procedure that can be performed in such critical situations.
