[Embolization of the pulmonary artery bed: hemodynamic and respiratory changes]

Hemodynamic and respiratory changes were studied during embolization of the pulmonary arterial bed in 20 rabbits after pentobarbital anesthesia. Air was insufflated into the auricular vein in the amount necessary to induce circulatory and respiratory changes. Circulatory changes were manifested by decreased arterial blood pressure, increased blood pressure in the right atrium, and aortal and pulmonary blood flow reduced to zero. The respiratory rate was diminished. A series of deep inspirations was followed by apnoe and death of the animal. (Fig. 5, Ref. 9.)
