Lung tissue remains vulnerable when blood supply is interrupted, so preservation focuses on reducing injury during the interval between retrieval and implantation. Cooling and flushing with a cold preservation solution lower metabolic activity and help protect graft quality. Effective control of this interval supports the possibility that the lungs will remain viable for transplantation.
The solution is flushed through the lungs after the airway and pulmonary vessels are divided. Its cold temperature reduces tissue metabolism, while the flush helps prepare the organs for preservation after retrieval. This step is central to limiting preservation-related damage before the lungs are cooled, packaged, transported, and implanted.
Surgeons carefully mobilize the lungs and then divide the airway and pulmonary vessels as part of retrieval. Managing these structures allows the organs to be separated for preservation while maintaining an organized transition from surgical removal to cold flushing. Precision during this stage contributes to graft quality and supports later transplantation.
Donor assessment and stabilization occur before the surgical retrieval begins. These steps help the procurement team establish suitable conditions for preserving the lungs and coordinating the operation. By addressing the donor first, the teams create a controlled pathway toward mobilization, vessel and airway division, flushing, cooling, and preparation for transport.
After cold flushing, the lungs are cooled further, packaged, and transported for implantation in the recipient. Packaging and transport extend the preservation workflow beyond the operating procedure, making careful handling and timing important to maintaining viability. The sequence connects retrieval with the recipient operation while limiting preservation-related damage.
The procedure makes donor lungs available for transplantation in patients with advanced respiratory disease. Its clinical value depends not only on retrieval, but also on preserving graft quality through stabilization, cold flushing, cooling, packaging, and transport. Coordination among procurement, critical care, and transplant teams helps connect a deceased donor with a recipient safely and efficiently.
