Q: While inflating donor lungs with oxygen, all of the following are true except?
A) It preserves the integrity of pulmonary surfactant
B) It improves the epithelial fluid transport
C) Lung inflation is limited to an airway pressure of 20 cm H2O
D) Inflation should be done with 100% FiO2
E) Trachea should be clamped after inflation
Inflation of lungs with oxygen during the ischemic time protects the lungs. All of the choices are correct except it requires only 30-50% of FiO2. In fact, 100% FiO2 can be injurious due to oxygen toxicity.
