Loss of Body Fluid after Open-Water Dives Conducted at Night in Warm Water

Abstract

Changes in body weight were recorded in 9 divers after nighttime dives in 26 degC (78 degF) water lasting 2-5 hours. A total of 34 manned dives were made during March-April 1991 as part of operator training for a SEAL delivery Vehicle (SDV). Loss of body fluid was estimated directly from changes in body weight (1 liter fluid per kg body weight). Dive duration averaged 195 +/ - 10 min. The average loss of body weight, from pre- to post-dive, was 1.31 +/- 0.12 kg. This translated to an estimated loss of body fluid of 1315 +/- 115 ml, or an hourly rate of loss of 440 +/- 44 ml per hour of dive.
