The use of nitrogen-oxygen as divers breathing gas

"The Use of Nitrogen-Oxygen Mixtures as Divers Breathing Gas" discusses the use of nitrogen-oxygen mixtures as a substitute for air by divers, detailing their advantages in terms of reduction of decompression obligation and extension of Ilbottom time". The paper concentrates especially upon the use of such mixtures by the NOAA Diving Program and the experience gained thereby. The NOAA-developed mixture known as NOAA NITROX I, in use since 1978, has been gaining increased acceptance in the diving community. A new mixture, NOAA NITROX 11, is still in the process of development. The NOAA-developed Continuous NITROX Mixer is also discussed.
