I suspect that they are talking about a hyperbaric oxygen chamber. It is a chamber that has oxygen in it at several times atmospheric pressure. The blood becomes more saturated with oxygen than is possible at atmospheric pressure therefore delivering more oxygen to healing tissues. I'm not familiar with human studies, but a study done on horses at the University of Tennessee while I was in school showed that hyperbaric oxygen therapy decreased wound healing time.
