Abstract
Dive computers and diveware are important underwater tools and staging devices across sport, technical, commercial, military, scientific, exploration and research diving sectors. They are supplanting traditional dive tables and their use is growing as decompression activities grow. While important dive computer parameters are displayed throughout the dive, DCS risk associated with arbitrary ascents to depths above the diver and surfacing risks are not yet encoded into underwater devices and diveware and that is the focus here. Risk estimation is needed for diver safety and sensible dive planning. We define and discuss end of dive (EOD) and on the fly (OTF) exponential risk functions for dissolved gas and bubble models using profile data correlated with the LANL Data Bank, a collection of computer downloaded mixed gas decompression profile with DCS outcomes across OC and RB diving. Risk estimates are based on profile supersaturations in excess over permissible supersaturations which is a standard metric. Comparative results are given for both nonstop and deep decompression diving on OC and RB systems. Computer implementation is easily accomplished within existing dive computers and diveware platforms. Techniques are underscored and results are discussed. References detail background information and work extends earlier published analyses for end of dive risk estimation.
