Abstract:

Attempts to define the no-decompression air limits for miniature swine were complicated by individual variance and bends tolerance development, but, based solely on clinical signs, they appear more resistant to bends than man except perhaps at depths beyond 140 feet. Although 100 feet90 minutes, 140 feet60 minutes and 180 feet30 minutes produces an 80 incidence of bends, they generally tolerate dives to from 60 to 180 feet for bottom times three times greater than the no-decompression limits for man. Temporary signs of middle ear distress are seen almost exclusively on ascent.
