Which two components are essential in CPR?

• A. Artificial respiration and cardiac compression.
• B. Defibrillation and oxygen therapy.
• C. Pulse checks only.
• D. CPR and stretching.

Answer: (A)

When CPR is performed, you need both circulating blood and delivering oxygen. Chest compressions push blood through the heart to the brain and other vital organs, while rescue breaths provide oxygen to the lungs so that the blood that circulates is oxygen-rich. Together, these two actions maintain circulation and oxygen delivery until advanced help arrives. The other options don’t fit because defibrillation is a separate treatment for certain heart rhythms, oxygen therapy alone doesn’t provide the necessary pumping action, and performing pulse checks or stretching isn’t CPR.
