The Physiology Of Breath-Hold Diving

This compilation of 25 papers from a 2-day workshop on the physiology of breath-hold diving is divided into six sections: historical notes, limits of breath-hold diving, breaking point analysis, thermal regulation and metabolic aspects, cardiovascular aspects, and safety aspects of breath-hold diving. The general discussions at the end of each session are included. The following papers are included in this publication: 1. Breath-hold diving: a brief history. Hermann Rahn pp. 1-3. 2. Von Trieleben's diving bell. Albert B. Craig, Jr. pp. 4-5. 3. Depth limits of breath-hold diving. Albert B. Craig, Jr. pp. 9-11. 4. Depth and time in relation to gas exchange. A.
