The Intensive Care Unit Oxygen Challenge Should Not Be Used for Donor Lung Function Decision-making

The intensive care unit Po2 is an unreliable screening test for donor lung function, particularly when one lung is clear and the other is unclear radiographically. In this setting, intraoperative surgical assessment and pulmonary venous Po2 should be the basis for determining donor lung suitability. This strategy may provide an opportunity to increase donor lung availability.
