541. _The method of resuscitating persons apparently drowned._ In the first instance, it is necessary to press the chest, suddenly and forcibly, downward and backward, and instantly discontinue the pressure. Repeat this without intermission, until a pair of bellows can be procured. When the bellows are obtained, introduce the nozzle well upon the base of the tongue, and surround the mouth and nose with a towel or handkerchief, to close them. Let another person press upon the projecting part of the neck, called "Adam's apple," while air is introduced into the lungs through the bellows. Then press upon the chest, to force the air from the lungs, to imitate natural breathing. (Appendix M.) -=-=-=-=-=-=-=-=-=-=-=-= 539. Give the first method for the treatment of cold. 540. The second method. 541, 542. How should persons apparently drowned be treated? -=-=-=-=-=-=-=-=-=-=-=-= 542. Continue the use of the bellows, and forcing the air out of the chest, for an hour at least, unless signs of natural breathing come on. Wrap the body in warm, dry blankets, and place it near the fire, to preserve the natural warmth, as well as to impart artificial heat. Every thing, however, is secondary to filling the lungs with air. Avoid all friction until breathing is restored. Send immediately for medical aid. 543. _The means of resuscitating persons asphyxiated from electricity, &c._ In apparent death from electricity, (lightning,) the person is frequently asphyxiated from _pa-ral´y-sis_ (palsy) of the respiratory muscles. To recover such persons, resort to artificial respiration. In cases of apparent death from hanging or strangling, the knot should be untied or cut immediately; then use artificial respiration, or breathing, as directed in apparent death from drowning. _Observation._ It is an impression, in many sections of the country, that the law will not allow the removal of the cord from the neck of a body found suspended, unless the coroner be present. It is therefore proper to say, that no such delay is necessary, and that no time should be lost in attempting to resuscitate the strangled person. 544. _The method of resuscitating persons apparently dead from inhaling carbonic acid gas._ When life is apparently extinct from breathing carbonic acid gas, the person should be carried into the open air. The head and shoulders should be slightly elevated; the face and chest should be sponged or sprinkled with cold water, or cold vinegar and water, while the limbs are wrapped in dry, warm blankets. In this, as in asphyxia from other causes, immediately resort to artificial respiration. -=-=-=-=-=-=-=-=-=-=-=-= 543. What treatment should be adopted in asphyxia from electricity?
