The invention discloses a gas delivery system for hepatic perfusion. A control module of the gas delivery system controls an oxygen delivery control component and a compressed air delivery control component to work according to output results of a hepatic artery neural network training model and a portal vein neural network training model, real-time detection results of a hepatic artery detectionmodule and a portal vein detection module are trained based on the neural network training models, preset oxygen partial pressure, partial pressure of carbon dioxide and blood oxygen saturation degree, and hepatic artery and portal vein gas delivery capacity can be accurately adjusted in real time, so that the oxygen partial pressure, the partial pressure of carbon dioxide and the blood oxygen saturation degree are stably outputted according to preset values. Moreover, universal wheels are arranged at the bottom of a base, so that the gas delivery system can be used and mounted in different surgical places. In addition, when the storage capacity of gas in an oxygen storage bottle and a compressed air storage bottle reaches critical values, an alarm module can timely inform operators of related information.
