What is the guideline for CPR breaths?

• A. Two every 4th second; for infants: cover nose and mouth.
• B. One breath every second.
• C. Two breaths after every 30 compressions.
• D. Five breaths after every set.

Answer: (A)

The idea being tested is how to pace breaths during CPR and how to deliver them effectively to infants. Giving two breaths in quick succession every four seconds creates a steady ventilation rate of about 30 breaths per minute, which helps maintain oxygen delivery during chest compressions without letting air go in too slowly or too rapidly. For infants, ensuring a proper seal by covering both the mouth and the nose with the rescuer’s mouth (or using a mask) directs air into the lungs and minimizes air leaks, making each breath more effective. Other patterns describe different rates or focus on a compression-to-ventilation ratio rather than this continuous, regular breathing rhythm, which is why this option is considered the best fit for the guideline being tested.
