Abstract:

Tolerance of restrained male rats to explosive decompression from sea level to 40,000 feet was found to be significantly reduced in animals previously exposed to whole body vibration of 25 cps frequency and 0.25 inch displacement for thirty minutes as compared wih the nonvibrated decompressed animals. The administration of an intraperitoneal injection of 1.0 ml of a 2 Xylocaine solution effectively increased this tolerance level. The major pathologic findings in the animals utilized in this study were confined to the lungs and consisted of pulmonary hemorrhage, edema, and atelectasis. Author
