Cognitive and perceptual deficits of normobaric hypoxia and the time course to performance recovery.
Many in-flight hypoxia-like incidents involve exposure to normobaric hypoxia following an oxygen delivery equipment failure. Studies have documented the effect of hypoxia on specific aspects of human performance. The goal of the present study was to establish the effects of acute hypoxia on cognitive, psychomotor, and perceptual abilities and to chronicle the time required for these capabilities to fully recover to pre-exposure levels. ⋯ Evidence from this study suggests an impairment of specific performance characteristics following hypoxic exposure - some for a considerable period of time. Mitigation efforts should focus more on the prevention of hypoxia exposure rather than relying exclusively on training operators to recognize and react earlier to hypoxic symptomology.

Case ReportsIsolated perivesicular hematoma after military parachuting.
Isolated perivesicular hematomas are uncommonly described and not an injury typically reported in the literature after parachuting or skydiving. ⋯ This injury pattern is uncommonly reported in the literature. An appropriate index of suspicion must be maintained or there may be a delay in diagnosis. Management of these injuries requires coordinated care between the trauma service, urology, and physical therapy.
