What ventilation rate should be used during cardiac arrest?

• A. 8-10 breaths per minute
• B. 4-6 breaths per minute
• C. 20-30 breaths per minute
• D. 2 breaths per minute

Answer: (D)

During cardiac arrest, the priority is to keep chest compressions continuous while providing just enough ventilation to support oxygenation without compromising perfusion. Ventilating at a very slow rate helps avoid increasing intrathoracic pressure too much, which can impede venous return to the heart and reduce the effectiveness of compressions. By delivering a small, controlled number of breaths—two breaths per minute—you limit interruptions and the risk of hyperinflation or gastric inflation, while still supplying some oxygen to the organs. Higher ventilation rates can disrupt CPR by causing longer pauses between compressions and by raising intrathoracic pressures, which lowers cardiac output during resuscitation. A rate of two breaths per minute aligns with keeping interruptions brief and maintaining perfusion, which is why it’s identified as the best answer for ventilation during cardiac arrest in this context.
