Which measure can correct respiratory depression in anesthetized mice?

• A. Increase oxygen supply
• B. Administer a reversal agent
• C. Provide assisted ventilation as needed
• D. All of the Above

Answer: (D)

When anesthesia causes respiration to slow or stop, you address the problem from multiple angles because the depressant effects, airway or breathing mechanics, and oxygen delivery can all play a role. Providing more oxygen raises the amount of oxygen in the blood even if breaths are shallow, helping tissue oxygenation while you manage the rest. If the depressant is a drug with a known reversal, giving the appropriate antagonist can rapidly restore respiratory drive and ventilation. And if breathing remains inadequate, assisted ventilation supports breaths directly, ensuring carbon dioxide is removed and oxygen reaches the lungs until the animal can resume spontaneous breathing. Because respiratory depression under anesthesia can involve several overlapping factors, using a combination of these measures is the most reliable approach, making all of the above the best choice.
