Purpose. The fundamental laws and concepts of underwater physics presented in
Chapter 2 (Volume 1) are basic to a proper understanding of mixed-gas diving
techniques. In mixed-gas diving, calculations requiring the use of the various gas
laws are vital to safe diving. A thorough working knowledge of the application of
the gas laws is mandatory for the mixed-gas diver. This chapter reviews the gas
laws.
Scope. This chapter discusses the theory and techniques used in mixed-gas
diving.
