FIGURE 2.

Example of infrared thermograms taken on mice C57Bl6 after leaving the hyperbaric chamber. The dark areas represent the coldest superficial areas and the light areas the hottest areas. In this example, the mouse on the left was considered during the clinical test to be suffering from decompression sickness. Dark areas were detected in the tail and its hind paws. The hottest area was generally not far from the ears. The mouse on the right was free from clinical signs indicating DCS. However, small cold area at the tip of the tail consecutive to the first blood sample taken before hyperbaric exposure was noted. It was also observed that in the tail the pilomotor reflex differs from the right-hand image: the swelling just before the beginning of the tail is larger on the right-hand image.
