Side 10 - With arms held straight, swing forward slowly, so that the weight of your body is gradually brought to bear upon the patient. The shoulder should be directly over the heel of the hand at the end of the forward swing. Do not bend your elbows. This operation should take about two seconds.
Side 11 - After two seconds, swing forward again. Thus repeat deliberately twelve to fifteen times a minute the double movement of compression and release, a complete respiration in four or five seconds.
Side 74 - ... 6. Continue artificial respiration without interruption until natural breathing is restored, if necessary, four hours or longer, or until a physician declares the patient is dead. 7.

Cow's milk which has become infected...
Side 74 - Not infrequently the patient, after a temporary recovery of respiration, stops breathing again. The patient must be watched, and, if natural breathing stops, artificial respiration should be resumed at once.
Side 105 - He had spent 77 full years trying to make the world a better place in which to live.
