Pulmonary barotrauma in submarine escape training.

Alveolar Air Resulting from Submarine Escape Training : a Post - Training Roentgenographic Survey

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 traininginvolved 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 i...

Pulmonary barotrauma in divers during emergency free ascent training: review of 124 cases.

INTRODUCTION Experience from treating diving accidents indicates that a large proportion of divers suffering from pulmonary barotraumas (PBT) or arterial gas embolism (AGE) were engaged in training dives, specifically emergency free ascent (EFA). We tried to verify this relationship and to calculate, if possible, the risk associated with normal recreational dives, training dives, and EFA traini...

Risk Factors for Pulmonary Barotrauma in

Study objectives: Pulmonary barotrauma (PBT) of ascent is a feared complication in compressed air diving. Although certain respiratory conditions are thought to increase the risk of suffering PBT and thus should preclude diving, in most cases of PBT, risk factors are described as not being present. The purpose of our study was to evaluate factors that possibly cause PBT. Design: We analyzed 15 ...

Extra-alveolar air resulting from submarine escape training: a post-training roentgenographic survey of 170 submariners. Rep No 550.

Oxygen or carbogen breathing before simulated submarine escape.

Raised internal pressure in a distressed submarine increases the risk of bubble formation and decompression illness after submarine escape. The hypothesis that short periods of oxygen breathing before submarine escape would reduce decompression stress was tested, using Doppler-detectable venous gas emboli as a measure. Twelve goats breathed oxygen for 15 min at 0.1 MPa before exposure to a simu...
