In solo BLS, after delivering 30 chest compressions, how many rescue breaths are given?

• A. 2 breaths
• B. 1 breath
• C. 3 breaths
• D. 4 breaths

Answer: (A)

In solo BLS for adults, the cycle is 30 chest compressions followed by 2 rescue breaths. This 30:2 pattern keeps blood flow high during compressions while still delivering enough oxygen to the lungs. The two breaths provide a quick, adequate tidal volume to oxygenate the blood without causing excessive interruptions or risk of gastric inflation. Each breath should last about one second and produce visible chest rise, then you resume compressions immediately to maintain perfusion. If the chest doesn’t rise, adjust head position and seal and try again. This consistent 30:2 rhythm continues until an advanced airway is in place or help arrives, ensuring ongoing circulation and oxygenation.
