Abstract:

Decompression from experimental, operational, and training dives at the Defence and Civil Institute of Environmental Medicine DCIEM has been carried out for many years under control of decompression computers rather than by means of published decompression tables. The XDC-2 digital decompression computer and dive monitor is presently in use at DCIEM. An evaluation program for determining and defining the operational limiting bottom times for different depths and the safety of using the computer by following exactly the displayed safe ascent during decompression has been started. In this report, the results of Phase I of the evaluation program, covering the depth range 36 to 54 meters of seawater msw, are presented. Seventeen chamber dives, consisting of 102 man-dives, were conducted using 9 different profiles. In order to assist in the evaluation of the XDC-2 profiles, two Doppler ultrasonic bubble detectors were used to monitor bubbles in the diving subjects for at least 3 hours and, in some cases, up to 7 hours after the start of decompression.
