Abstract: A system for ex vivo normothermic organ preservation may include a pump configured to circulate a perfusate through a perfusion circuit, an oxygenator coupled configured to oxygenate the perfusate, a heat exchanger configured to regulate a temperature of the perfusate and an organ chamber having an internal volume configured to receive an organ. The perfusion circuit may be configured to be coupled in fluid communication with an arterial inlet into the organ. The system may also include a processor and memory having instructions that when executed by the processor cause the system to carry out a method. The method may include changing a temperature of the perfusate from an initial temperature to a normothermic temperature within a normothermic temperature range, maintaining the perfusate within the normothermic temperature range for at least one hour, receiving sensor data for perfusate parameters, and displaying the sensor data.
