How many breaths should be given after 30 compressions during CPR?

• A. One
• B. Two
• C. Three
• D. Four

Answer: (B)

In CPR, the correct ratio of chest compressions to rescue breaths for an adult is 30 compressions followed by 2 breaths. This sequence is vital for maintaining effective circulation and oxygenation during cardiac arrest. The two breaths after the 30 compressions ensure that oxygen is delivered to the lungs, improving the chances of restoring a heartbeat and promoting survival. Adhering to this 30:2 ratio is critical because it strikes a balance between ensuring adequate blood circulation through compressions and providing necessary oxygen through breaths. This method enhances the effectiveness of CPR by supporting the victim's oxygenation while also performing the vital task of circulating blood throughout the body. This is especially important in the context of respiratory or cardiac emergencies, where both functions need to be prioritized for the best possible outcome.
