The determination of surface tension of blood from male subjects was investigated for its relationship to susceptibility to decompression sickness. The use of an anticoagulant, protamine sulfate, solved the problem of duplicate measurements S.D. 0.5 dyne cm.1. Venous blood samples were collected from 22 men 3 times a day for 3 days a week for 2 weeks. Hematocrit determinations were also made on the last 10 subjects. The age of each subject was recorded but, like the hematocrit, no relationship was found between age and surface tension. The day mean, based on all the subjects for 2 weeks, ranged from 56.9 to 64.9 dynes cm.1 and was not influenced by time of day. Author
