Submarine escape training for submarine personnel has been conducted by the U. S. Navy since 1930. By 1957, more than 250,000 ascents had been recorded. Most casualties due to this training involved extra-alveolar air and/or embolism, and those few casualties which have occurred had usually been recorded and reported. In view of this, several questions were asked, among them one concerning the incidence of extra-alveolar air after submarine escape training in personnel who are not considered to be casualties. Chest roentgenograms of 170 personnel taken immediately after undergoing routine submarine escape training were examined. Two men were found to have roentgenographic evidence of extra-alveolar air. The close association of extra-alveolar air with air embolism is postulated and the true incidence of these entities after submarine escape training is questioned. It was concluded that the incidence of air emboli and/or extra-alveolar air following submarine escape training may be much greater than previously suspected. (Author)
