The purpose of this study is to determine the practicality of performing a future, large-scale study. The future study will look at the effect of mechanical ventilation in neurologically deceased (brain-dead) lung donors who are positioned to lay flat on their stomach (prone position), compared to donors who are positioned to lay flat on their back (supine position). The study will also look at the potential impact of prone positioning of the donor on transplant recipients of the study organs.

The investigators are doing this study because the investigators want to increase the availability of donor lungs for lung transplant. Lung transplant is a life-saving treatment for individuals with lung disease, but there are not enough donated lungs to meet demand. Researchers are looking for better ways of preventing donated lungs from becoming unsuitable for transplant. Because of this, the goal of our study is to test whether prone positioning in neurologically deceased (brain-dead) lung donors can improve donor lung function and decrease complications, potentially increasing the number of donor lungs that can be used for transplant.
