SYLVESTER'S METHOD—FIGURE 1
Rule 2. To Maintain a Free Entrance of Air Into the Windpipe.—Cleanse the mouth and nostrils; open the mouth; draw forward the patient's tongue, and keep it forward; an elastic band over the tongue and under the chin will answer this purpose. (Fig. 1.)
Rule 3. To Imitate the Movements of Breathing.—First, Induce inspiration. Place yourself at the head of the patient, grasp his arms (at the elbow-joints), raise them upward by the sides of his head, stretch them steadily but gently upward, for two seconds. By this means fresh air is drawn into the lungs by raising the ribs. (Fig. 2.)

Secondly, Induce Expiration.—Immediately turn down the patient's arms, and press the elbows firmly but gently downward against the sides of the chest, for two seconds. By this means foul air is expelled from the lungs by depressing the ribs. (Fig. 3.)
Thirdly, Continue These Movements.—Repeat these measures alternately, deliberately, and perseveringly fifteen times a minute, until a spontaneous effort to respire be perceived. By these means an exchange of air is produced in the lungs similar to that effected by natural respiration.
