Artificial respiration and respirators

Drinker's "Iron Lung" and Other Artificial Respirators

Motion by releasing the oxygen from the cylinder. There was also a bag (as in Haldane's oxygen apparatus) Which served to keep the oxygen pressure from rising too high in the delivery tube. Thus the oxygen on its Way to the face kept the pump working, and this produced alternately a negative and positive pressure in the delivery tube provided the face-piece was closely applied to the face. This...

Artificial Respiration

lowering the arms gave still less favourable results. Howard's direct method of alternately compressing the lower chest wall by the spread hands and letting go sharply was found to cause a much larger air entry, but still below the normal; but it is conducted in the supine attitude which, in many cases, as in drowning, prevent other useful indications from being fulfilled and is sometimes subje...

A New Method of Artificial Respiration

The two main recognized methods of artificial respiration, namely, Schafer's and Silvester's, depend for their efficacy on the elastic recoil of the chest wall and diaphragm, which can happen only when the integrity and tonicity of the muscles of the respiration are maintained. Schafer's (1907-8) method consists in Maying the subject prone, and pressing gradually for three seconds with both han...
