The purposes of hyperbaric oxygen therapy (HBO), which is an allopathic treatment for gas embolism, dysbarism, etc., are to collapse the bubbles produced in blood and to improve ischemic hypoxia by increasing dissolved oxygen. A pertinent curative condition for additional pressure is required as HBO is carried out because the artificial addition of pressure to the human body is attended by certain danger such as barotrauma and oxyges toxicity. In the present paper, under the operative condition of HBO, the compound effect of additional pressure and gas diffusion on the shrinking process of bubbles in blood is made clear, and the dynamic mechanism of HBO is clarified. It is found that the shrinkage of larger bubbles in blood requires greater additional pressure, but that there is no need to decrease the time over which pressure is increased.
