Pulmonary Barotrauma and Chest Dimensions: Preliminary Report*
Royal Navy
In the past, the role of chest cage shape and dimensions in relation to the development of lung disease has been considered on a theoretical basis. The present study is a retrospective survey of the chest dimensions of a group of submarine escape trainees who had suffered pulmonary barotrauma, as compared to those of age-matched controls, to determine whether the size and shape of the lungs and chest wall are influential in helping to predict which individuals might be at higher risk of developing pulmonary barotrauma during submarine escape training. It was determined that there are statistically significant differences between accident and age-matched control populations on the basis of vertical and horizontal chest radiograph measurements, and there was some indication that age is an important factor in assessing the separation between accidents and controls. The radiograph measurements are described, a discriminant function analysis which attempts to give some measure of maximal separation between the population is discussed, and implications for pre-selection of at-risk trainees and future research are considered.
