Abstract : G-induced loss of consciousness (G-LOC) is a common event and has led to the loss of many aircraft and aircrew. While most body systems are ultimately affected, the final common path for its initiation is an inadequate supply of oxygen to the brain. Thus, a measure of cerebral oxygen sufficiency could provide a specific monitor for incipient G-LOC and serve either as a warning to the pilot or as a trigger for an autorecovery system. Multiwavelength near-infrared spectrophotometry permits the non-cerebral microcirculation, and also of the oxygen status of cytochrome-c oxidase within the brain cells.
