ReviewPhysician roles in aeromedical evacuation: current practices in USAF operations.
Physicians play an increasingly important role in the critical medical process of aeromedical evacuation (AE). Incomplete or inappropriate preparation for AE can result in increased patient discomfort, and in the worst cases, potentially serious or insurmountable in-flight medical problems. During military operations and in response to natural disasters, physicians are responsible for four processes necessary for a successful AE mission. ⋯ S. military patient evacuation system is comprised of three principal transportation phases: casualty evacuation; inter-theater AE; and intra-theater AE. Important elements of the USAF AE system are patient movement requirements centers, the validating flight surgeon, aeromedical staging facilities, AE liaison teams, aeromedical crews, and critical care air transport (CCAT) teams. Important medical aspects unique to AE include the effects of flight physiology on medical conditions, oxygen limitations, and distinctive medication and supplies requirements.

Venous bubble count declines during strenuous exercise after an open sea dive to 30 m.
The effect of post-dive exercise on bubble formation remains controversial, although the current practice of divers and aviators is to avoid strenuous exercise after diving. Previously, we have shown that exercising 24 h before a dive, or during a decompression stop, significantly reduces bubble formation in man. The objective of this study was to determine whether a short period of strenuous post-dive exercise promotes venous bubble formation. ⋯ These results suggest that post-dive strenuous exercise after a single field dive reduces post-dive gas bubble formation in well-trained military divers. Additional findings are needed for normal sports divers.
