A review of the LEM probabilistic decompression model for SCUBA divers
by
Beverley Horn
University of Canterbury

A risk present during any dive is the risk of decompression illness. To reduce this risk divers ascend from their dives in prescribed steps. The depth and duration of these steps is determined from numerical models calibrated with manned diving trials. This talk describes and reviews one such model, the LEM decompression model developed by the US Naval Medicine Research Institute. The model has two components: (a) A dynamical system describing a simplified physiological model of the gas kinetics in the body tissues during and following the dive. (b) Survival analysis techniques convert the tissue gas pressures to a probability of decompression illness.
