See Article History Artificial respiration, breathing induced by some manipulative technique when natural respiration has ceased or is faltering.
Such techniques, if applied quickly and properly, can prevent some deaths from drowningchoking, strangulation, suffocationcarbon monoxide poisoningand electric shock. Resuscitation by inducing artificial respiration consists chiefly of two actions: To be successful such efforts must be started as soon as possible and continued until the victim is again breathing.
Various methods of artificial respiration, most based on the application of external force to the lungs, were once used. Methods that were popular particularly in the early 20th century but were later supplanted by more effective techniques included the modified Silvester chest-pressure—arm-lift method, the Schafer method or prone-pressure method, developed by English physiologist Sir Edward Albert Sharpey-Schaferand the Holger-Nielsen method.
In the Silvester method, the victim was placed faceup, and the shoulders were elevated to allow the head to drop backward. The cycle was repeated about 12 times per minute. In the s Austrian-born anesthesiologist Peter Safar and colleagues found that obstruction of the upper airway by the tongue and soft palate rendered existing artificial ventilation techniques largely ineffective.
The researchers proceeded to develop techniques to overcome obstruction, such as lifting of the chin, and subsequently demonstrated that mouth-to-mouth respiration was superior to other methods in the quantity of air that could be delivered in each respiratory cycle tidal volume.
Mouth-to-mouth breathing soon after became the most widely used method of artificial respiration. If a victim was choking before falling unconscious, the Heimlich maneuver may be used to clear the airway before beginning mouth-to-mouth respiration.
Kouwenhoven and colleagues to restore circulation, giving rise to the basic method of CPR cardiopulmonary resuscitation. Inafter researchers determined that mouth-to-mouth resuscitation too often resulted in slowed or stopped circulation, a hands-only method for adult victims, which uses only continuous chest presses, was adopted by the American Heart Association see cardiopulmonary resuscitation.

Artificial respiration alone before cessation of circulation or artificial respiration together with intracardial injection of epinephrine rescued nicotine-poisoned dogs (Franke and Thomas, ). Nicotine-induced convulsions can be blocked by certain anticholinergic drugs such as diethazin and diphenhydramine.
