Abstract : The ventilatory response to 5% CO2 was studied in a group of seven tank instructors during a period of heavy water-work and after a lay-off period of three months in which the Escape Training Tank was overhauled. The respiratory response to CO2 was found significantly lower during the period of active skin diving suggesting an adaptation of respiration to a condition involving daily repeated breatholding maneuvers. Small but consistent changes in the respiratory pattern on air (decrease in respiratory rate) suggest that an alteration in the pattern of breathing plays a role in the adaptation of the CO2 ventilation response. Studies now in progress are expected to clarify the significance of the observed changes in relation to the total complex of factors involved in the adaptation to skin diving. (Author)
