Question

Why is sodium bicarbonate used in cardiac arrest?

Answer 1

Sodium bicarbonate (NaHCO3) is used primarily to combat acidosis, although it’s the treatment of choice in certain cases of overdose. It works by mixing with lactic acid that forms in low perfusion states and in periods of inadequate oxygenation, such as shock and cardiac arrest. It is then converted to a form of carbonic acid that turns into carbon dioxide, and in turn, is expelled through the lungs during ventilation.
