Abstract:

The respiratory responses to carbon dioxide inhalation were determined in subjects before diver training. The subjects were Hospital Corpsmen who had either never previously been exposed to the hyperbaric environment or had not dived for at least four months. They then attended the 1st Class Diver School at the USN School of Diving and Salvage, in which seven subjects passed and five failed the course. Those subjects who were successful were re-examined on completion of their training. The data support previous findings that adaptation to the hyperbaric environment occurs, particularly in a decrease of the sensitivity to carbon dioxide inhalation. Sensitivity to hypoxia is much less affected. The subjects who did not complete diver training had a greater mean initial respiratory response to carbon dioxide inhalation than those who passed the course. It is suggested that the sensitivity to carbon dioxide of a diver trainee is negatively correlated with his likelihood of success in training. Author
