What is the standard management for hypoventilation under anesthesia?

• A. Desaturate
• B. Increase fresh gas flow
• C. IPPV
• D. Admin analgesic

Answer: (C)

When a patient under anesthesia becomes hypoventilated, the problem is not enough ventilation to clear the CO2 produced by metabolism. The standard management is intermittent positive-pressure ventilation (IPPV), which you control to deliver set breaths—adjusting tidal volume and respiratory rate as needed—to increase minute ventilation and reduce the elevated CO2 toward normal. Increasing fresh gas flow can raise oxygen levels but does not reliably correct CO2 retention if the patient’s ventilation remains inadequate, so it doesn’t address the root problem. Administering analgesics would tend to suppress breathing further and worsen hypoventilation. Using IPPV directly targets and corrects the deficient ventilation, restoring appropriate gas exchange during anesthesia.
