A patient suffering from acute smoke inhalation also had a long medical history that included reflex sympathetic dystrophy syndrome of the left foot and ankle. The entire foot and ankle were tender and cool to palpation; range of motion was severely reduced. She was referred for hyperbaric oxygen therapy, and 15 min into the the first treatment (46 min at 60 fsw) she reported a lessening of the pain in her foot; moreover, the foot was less cyanotic and warmer to the touch. Subsequent treatments continued to improve her conditions and for longer periods of time.
