How should hypoxia be addressed during cardiac arrest?

• A. Ensure airway and ventilation with appropriate oxygenation (high-flow oxygen or bag-valve-mask ventilation); correct ventilation issues quickly.
• B. Administer diuretic therapy
• C. Focus only on chest compressions, skip ventilation
• D. Delay airway management until ROSC

Answer: (A)

Maintaining oxygen delivery is essential when the heart isn’t pumping. During cardiac arrest, tissues quickly become deprived of oxygen, so addressing hypoxia by securing the airway and providing effective ventilation is a priority. The best approach is to establish the airway and ventilate with adequate oxygen—using high-flow oxygen or a bag-valve-mask—to correct ventilation problems quickly. This ensures the blood that reaches the brain and heart carries more oxygen, supporting the chances of return of spontaneous circulation. Other options don’t address the immediate need for oxygen delivery. Diuretics don’t help in the acute resuscitation scenario and won’t improve oxygenation. Focusing only on chest compressions without ventilation neglects the oxygen component, which can worsen outcomes. Delaying airway management until ROSC misses a critical window to restore oxygenation during arrest.
