Technical divers have observed that many ailments can be avoided by including “deep stops” in their profiles. A closer examination of the decompression model reveals that this practice serves to reduce or eliminate excessive overpressure gradients. Knowing this, the model can be modified to provide precise control of gradients and stops can be calculated within the decompression zone to the depth of the “deepest possible decompression stop.”
