To meet the growing demand for precision protection in advanced high-performance fighter aircraft and the increasing life-support requirements of pilots, intelligent oxygen systems integrating physiological monitoring, state prediction, and active intervention are expected to become a key component of next-generation life-support systems. Accordingly, the evolution of airborne oxygen systems and recent advances in intelligent oxygen technologies worldwide were systematically reviewed. Particular attention was given to the application potential and major limitations of three enabling technologies: electronic oxygen regulation, multimodal physiological monitoring, and physiological state prediction. Current evidence indicates that electronic oxygen regulators provide the engineering foundation for incorporating physiological information into the oxygen-supply control loop. However, sensor reliability under complex flight conditions, individualized prediction, appropriate matching of intervention strategies to physiological risks, closed-loop stability, and in-flight validation remain major barriers to practical implementation. Future research should integrate multimodal physiological information, hybrid physiology-data modeling, and staged experimental validation to achieve coordinated regulation of pilot physiological status, cockpit environment, and oxygen-supply equipment.
