Artificial Respiration Explained

Artificial respiration, the history of an idea.

INTRODUCTION THE SIMPLE automatic act of breathing is essential to life, but may be interrupted in a variety of ways. Cessation of this act of breathing is not necessarily fatal if there is some means available to produce artificial respiration. However, should this assistance be lacking then death will always supervene. This article proposes to sketch the history of the various means of artifi...

Impairment of oxygen transfer in the lung by increasing oxygen concentration during halothane and trichloroethylene anaesthesia.

Two groups of 10 patients were studied during artificial ventilation with a mixture of oxygen, nitrogen and either halothane or trichloroethylene. Arterial blood and respiratory gas smapling was performed at FIO2 values of 0.33, 0.5 and 0.75. The efficiency of oxygen transfer, expressed as the difference between pulmonary end-capillary and arterial oxygen content, was found to decrease progress...

Dr. Fayrer's Treatment of Snake-Bite by Artificial Respiration

In the November (1872) number of the Indian Medical Gazette I published my first series of experiments oil artificial respirution in snake-poisoning, and the results I considered unfavourable. Judging, however, from the experiments I have since made, I am led to believe that the unsatisfactory results were due more particularly to faulty artificial respiration. It will be observed by the follow...

Mechanics of breathing, gas distribution and functional residual capacity at different frequencies of respiration during spontaneous and artificial ventilation.

Nine healthy volunteers were investigated, both while awake and breathing spontaneously, and while anaesthetized with IPPV, in all cases at rates of both 12 and 24 b.p.m. Gas flow and volume were measured with a pneumotachography. The transpulmonary pressure (the pressure difference between the trachea or the buccal cavity and the oesophagus) was also recorded. The distribution of gas was analy...
