Out of the Decompression Matrix provides an analytical approach to diver behaviour and decompression. It provides practical guidance for good diving behaviour and clear advice on decisions faced by all divers before, during and after every dive. In addition to traditional decompression theory the book examines decompression avoidance strategies, use of personal computers, multi-level diving and buoyancy and ascent management. Further chapters provide detailed information on gas management, risk assessment and decompression illness from denial to recognition then treatment.
