Gravity-induced loss of consciousness (G-LOC) is a major threat to fighter pilots and may result in fatal accidents. High +Gz (head-to-foot direction) acceleration force induces cerebral blood loss and results in gray-out, black out, and G-LOC. Countermeasures to avoid G-LOC include anti-G strain maneuver, anti-G suits, and pressure breathing for G, etc. They effectively decrease G-LOC incident, but have not eradicated it. Objective detection of G-LOC related symptoms is the prerequisite. In spite of many G-protective measures, G-LOC monitoring system has yet to be developed. Technologies for non-contact monitoring or motion capture have ventured into health care market. Real time physiological sensing for heart rate, body temperature, respiratory rate, etc, is used to medical, health care, physical fitness and sports area. Those advanced technologies might have potential for future G-LOC monitoring. This article reviews current status and future of countermeasures for G-LOC, and related technologies.
