Independent Lung Ventilation (ILV) typically requires which of the following?

• A. It uses a single-lumen tube
• B. It aims to equalize pressures between lungs
• C. It requires direct access to each lung and often uses a double-lumen tube
• D. It is used only for noncontaminated lungs

Answer: (C)

Independent Lung Ventilation relies on isolating each lung so they can be ventilated with different settings as needed. To achieve true separation, you need direct access to both lungs, which is usually provided by a double-lumen endotracheal tube that splits airflow into two independent channels. A single-lumen tube cannot isolate the lungs, so it cannot support independent ventilation of each side. The aim in ILV isn’t to make pressures equal between the lungs; in fact, you may set different pressures or tidal volumes for each lung to protect the more injured or noncompliant one while ventilating the other. ILV is particularly useful when one lung is damaged or contaminated, and preventing cross-contamination is a key reason for its use. So, the essential requirement is direct access to each lung with a device like a double-lumen tube to enable separate ventilation paths.
