- Abstract
In military flight even nowadays, one of the most important aeromedical hazards leading to sudden incapacitation is the threat of hypobaric hypoxia. Based on the data of flight safety statistics and disaster investigations there is a reasonable suspicion in increased rate that recently developed OBOGS (on- board oxygen generating system) cannot provide full oxygen supply, or the cerebral circulation cannot maintain proper oxygen utilization for every moment. There is a certain risk for pilot as an operator to lose physical- mental performance momentarily. Based on our experiments in bar chamber during VR (Virtual Reality) flight mission we concluded that in brain cells a long lasting oxygen utilization problem can commence due to the controversial compensation mechanisms and unpredictable stress response of heart- brain axis. The analysis of hypoxic incidents and fatal events (as UPEs, unexplained physiological events) on-board of most advanced fighter aircrafts is especially important after infection in Covid-19 pandemic, provoking even further aggravated pathophysiological abnormalities in virus pneumonia and ARDS (Adult Respiratory Distress Syndrome), even after recovery from acute phase.
