In hemorrhage or collapse, the immediate indication is to restore the circulation of the brain centers, particularly of the vasoconstrictor and respiratory; so mechanical measures, to increase the blood of the trunk, such as raising the feet and lowering the head, or tightly bandaging the limbs, toes, or fingers upward, are valuable measures. By this latter method the blood-pressure may sometimes be raised 30 or 40 millimeters of mercury, and the bandages may be kept on for half an hour without harm to the limbs.

For use in shock Crile has devised a pneumatic suit, by which the surface pressure on the body may be increased or reduced at will. By it he has raised the arterial pressure as much as 75 mm., and maintained the rise for some time. To accomplish the same purpose, Meltzer recommends bandaging the abdomen and placing weights upon it.
