Place the patient on a portable platform, 3x7 feet, and have the same balanced on the seats of two chairs, or what is better, a narrow bench supported by four legs, about three feet high. The patient first is placed with the face downwards, and one of the arms under the forehead as recommended in Marshall Hall's method. An assistant is placed at the foot end of the platform, with a firm hand to see-saw it as directed by the surgeon. This reciprocating motion is to be in harmony with a normal respiratory action. The first few movements, slowly executed will dislodge the fluids of the throat; the patient is now turned on his back, and Silvester's method enforced by raising and depressing the arms; but especial care is to be observed that the head goes down simultaneously with each extension of the arms, and as the feet go down, the arms are brought to the sides of the body. The arms are under the management of two assistants, and two more are required where the lower extremities are likewise brought into requisition to favor the action on the diaphragm and thoracic and abdominal muscles. Many a case of artificial respiration prove a failure because abdominal tension was overlooked. As the head goes down, the abdominal viscera fall against the diaphragm and by the aid of the thoracic and abdominal muscles, brought into action by the extremities, force the air, mucous and all foreign matter from the lungs and air passages, the blood also flows to the brain, right side of heart and lungs, stimulating these organs. Reverse this movement by bringing down the feet, the abdominal organs fall away from the diaphragm, drawing it along with them, an operation greatly facilitated by the aid of the extremities; the air rushes into the lungs to fill the vacuum created. The blood flows to the right and left side of the heart, and lower extremeties in this way imitating the normal movements of respiration and circulation as nearly as may be. All the minor details of exciting respiration by artificial means, are to be closely followed in enforcing this plan.
