Neon Decompression

Abstract

During the current contract year this Laboratory has conducted a feasibility program on the applications of neon in mixed-gas diving. The neon source studied was a by-product of the manufacture of atmospheric gases; it is composed of 25% helium, 75% neon. To develop the decompression tables, modifications of classical theory were applied to existing diving data, mainly experience with helium. The resulting decompression schedules proved to be unexpectedly troublesome in causing sensory problems and delayed effects-- whether designed for helium or neon--and satisfactory decompressions could be achieved only if oxygen breathing was included. The planned array of tests over a range of depths and times (150-400 feet sea water and 30-120 min) was set aside, and efforts were concentrated on producing a dependable table for 250 feet sea water/60 min.
