More than 100 years ago, the English chemist William Henry discovered a law of nature: that the quantity of gas in physical solution in a fluid is directly proportional to the partial and absolute pressure of that gas above the surface of that fluid.

In our time this maxim, known to every high school student as Henry's Law, has led to the development by modern medicine of the apparatus and techniques of hyperbaric oxygenation.

With hyperbaric oxygen chambers built or under construction at many medical centers, interest is high among physicians concerning the uses, effects, and dangers of hyperbaric oxygenation as a medical procedure. The interest was apparent when physicians jammed an auditorium to listen to a "Symposium on Hyperbaric Oxygen Phenomena" presented at the 113th Annual Convention of the American Medical Association in San Francisco in June.

Much of the pioneering work in hyperbaric oxygenation was done in the
