The G-LOC Syndrome
Abstract
Acceleration (+GZ)-induced loss of consciousness (G LOC) is but one isolated symptom that results when central nervous system (CNS) function is altered by G-stress. Other symptoms and changes also result when reduction of oxygenated blood flow to the CNS occurs. The complex of symptoms and changes that result from G-stress occur in close temporal relationship and therefore form a G-LOC syndrome. Recognition of the G-LOC syndrome serves to include the associated symptoms as part of the normal response to CNS ischemia/hypoxia. This recognition is important in reducing the potential for unnecessary aeromedical evaluation or disqualification of normal aircrew who have an uncomplicated G-LOC episode. It also serves to ensure that abnormal responses can be more clearly identified. Recognition of the G-LOC syndrome also serves to enhance the understanding that G-LOC is a primary neurologic disturbance induced by G- stress. We propose to clarify the existing situation by recognizing the G-LOC syndrome as including all of the +GZ-induced CNS symptoms, either alone or in combination, as a normal response to +GZ-stress in normal human beings.
