What is the best management for a patient in severe respiratory acidosis?

• A. Bronchodilators
• B. Administer bicarbonate
• C. Provide supplemental oxygen only
• D. Mechanically ventilate the patient

Answer: (D)

When ventilation fails to remove enough CO2, the body becomes acidotic. The fastest and most reliable way to reverse this in a severe situation is to support and control breathing with mechanical ventilation. By delivering controlled breaths, a ventilator increases minute ventilation, removes excess CO2, and helps restore a normal pH while also protecting the airway and optimizing oxygen delivery for the patient.

Bronchodilators can help if reversible airway obstruction is contributing, but they don’t reliably fix severe hypercapnia. Administering bicarbonate is not a primary treatment for respiratory acidosis and can worsen CO2 retention and intracellular acidosis. Providing supplemental oxygen alone improves oxygenation but does not address the underlying ventilation problem, so it won’t correct the elevated CO2 or acidemia.
