Mechanical methods for initiating respirations that have ceased from any cause have been the subject of frequent study and controversy. The lesser or pulmonary circulation, though intimately associated with respiration, has not been the subject of adequate study with the chest closed. An improved technic has been developed for measuring the effective pulmonary and the effective systemic blood pressure in animals with closed chest and premedicated with 3 to 5 mg. of morphine sulfate per kilogram. The pulmonary and systemic blood pressures have been recorded while respiration was maintained with each of the following resuscitators:Anesthetic machine.Emerson respirator (iron lung).Kreiselman infant resuscitator.Kreiselman "bellows" resuscitator.Artificial pulmonary ventilation for operating room (Mautz model).Lung ventilator.Emerson resuscitator, J. H. model.METHODSAll operative procedures were accomplished with the aid of local infiltrations of 1 per cent procaine hydrochloride. The trachea was |
