During the past four or five years a number of mechanical devices for resuscitation from electric shock, drowning, and asphyxiation by poisonous gases have appeared on the market. Properly speaking, none of these devices is anything more than a means of supplying artificial respiration with air more or less enriched with oxygen. There has been a general failure to distinguish between a method for maintaining the pulmonary ventilation and methods (for practical purposes as yet undiscovered) for restoring the heart beat after fibrillation or standstill, and for counteracting the paralyzing effects of asphyxia on the nerve centers of the brain and cord. This has resulted in the term "resuscitation" apparatus being generally applied. It is important to keep in mind the limited character of this resuscitation.
The demand for such apparatus arises from the modern "safety first" movement. Any piece of apparatus which proved fairly effective for resuscitation would undoubtedly
