=Sylvester’s Method.=—Lay the patient upon his back; kneel above
the head, take firm hold of the arms above the elbow, and move them
horizontally—first away from the body, then over the head until the
hands touch behind; pull them backward for a few seconds. This process
expands the chest cavity, and the lungs are filled with air, inducing
inspiration. Return the arms to the first position, and make strong
pressure on the sides of the chest and epigastrium to expel the air
and effect expiration. Movements should not be too rapid; they should
be repeated about sixteen times a minute. In case of apparent want of
success, persist in the treatment until it has been ascertained that
the heart has ceased to beat.
=Marshall Hall’s Method.=—Roll the patient over on his breast, make
gentle pressure on the back, then turn the body gently but completely
on the side, and again make gentle pressure on the back. Repeat these
movements fifteen times every minute.
Artificial respiration may be kept up for hours before the faintest
symptoms of life are shown.
