Hyperbaric oxygen therapy continues its cameo role in ABC's science fiction drama Defying Gravity. In last night's episode, as well as the two preceding, HBOT gets a brief mention for its role in wound care. A crew member loses a thumb in a zero-gravity accident and has it reattached. Hyperbaric treatment speeds recovery so she can pilot the Venus lander with all ten digits. In 2053, that's quicker than growing a new thumb.
