title: Thoracic and pulmonary radiographic modification during immersion in apnea: 1--a special apparatus.
abstract: Thoracic and pulmonary radiographic modification during immersion in apnea, were studied. An Apparatus "Nuclearisub" was used, it consists of two parts: An x-ray generator (100 KV, 40 mA) and a image intensifier tube (brightness gain 1200) with a transistorized telecamera. Through continuous radioscopy during immersion, can be analyzed the variations caused by redistribution of the blood, as well as the changes in pressure.
