What is a common management option for unilateral lung disease to improve ventilation?

• A. Nasal CPAP
• B. Increase PEEP On Both Lungs
• C. Double Lumen ETT
• D. Suction Only The Affected Lung

Answer: (C)

Isolating and ventilating each lung independently is a key strategy when one lung is diseased. A double-lumen endotracheal tube provides two separate airways and cuffs, one to each mainstem bronchus, so you can ventilate one lung with its own settings while the other lung is deflated or managed differently. This allows the healthy lung to receive appropriate tidal volume, PEEP, and FiO2 to optimize gas exchange, while reducing ventilation of the diseased lung and protecting it from excessive pressures. In unilateral disease, this independent ventilation helps improve overall oxygenation and ventilation more effectively than trying to manage both lungs with the same settings. Other options either affect both lungs equally or don’t offer true lung isolation, which is why they’re less effective in this scenario.
