Methods
We retrospectively reviewed all OCS Lung recoveries performed by our recovery team, using packed red blood cells (pRBC) from May 2019 to January 2021. Initially, units were stored using passive refrigeration with the Performance cooler at a temperature range of 1 to 6 °C for 4 hours. Subsequently, thermal control technology with the ProMed cooler was utilized to maintain the same temperature range for 72 hours.
