The effect of air pressure on edema and healing of scalded tissue of rats.

To study the effectiveness of using high-pressure air on edema and healing of second-degree scald burns in rats. A self-designed high pressure airtight box in which the air pressure can be controlled is used to observe the edema and healing time of second degree burned tissues in rat under different air pressures. With the air pressure increased by 30 cm H2O, there was a significant reduction of edema, exudation and healing time of the scalded tissue. Increasing air pressure can reduce edema, exudation and healing time of scalded tissue.
