Hemodynamic and functional changes in xenogenic, perfused, isolated lungs. 1976

K Kusajima, and J C Aust, and S D Wax, and W R Webb

Hyperacute pulmonary rejection was reproduced by perfusion of the isolated lung with heparinized heterologous blood. The cat lung was perfused with dog venous blood at a pressure of 30 mm. Hg. Pulmonary hemodynamic and functional studies showed that blood flow decreased to 14 per cent of the control and pulmonary vascular resistance increased sevenfold. Dynamic pulmonary compliance decreased only slightly to 83 per cent at 15 minutes, but normal pH, PO2, and PCO2 were maintained in the pulmonary venous blood even 15 minutes after the start of perfusion, because perfusion was decreased to a greater extent than ventilation.

UI MeSH Term Description Entries
D008168 Lung Either of the pair of organs occupying the cavity of the thorax that effect the aeration of the blood. Lungs
D008170 Lung Compliance The capability of the LUNGS to distend under pressure as measured by pulmonary volume change per unit pressure change. While not a complete description of the pressure-volume properties of the lung, it is nevertheless useful in practice as a measure of the comparative stiffness of the lung.

D010477 Perfusion Treatment process involving the injection of fluid into an organ or tissue. Perfusions
D011652 Pulmonary Circulation The circulation of the BLOOD through the LUNGS. Pulmonary Blood Flow,Respiratory Circulation,Circulation, Pulmonary,Circulation, Respiratory,Blood Flow, Pulmonary,Flow, Pulmonary Blood,Pulmonary Blood Flows

D002415 Cats The domestic cat, Felis catus, of the carnivore family FELIDAE, comprising over 30 different breeds. The domestic cat is descended primarily from the wild cat of Africa and extreme southwestern Asia. Though probably present in towns in Palestine as long ago as 7000 years, actual domestication occurred in Egypt about 4000 years ago.

D004285 Dogs The domestic dog, Canis familiaris, comprising about 400 breeds, of the carnivore family CANIDAE. They are worldwide in distribution and live in association with people. (Walker's Mammals of the World, 5th ed, p1065) Canis familiaris,Dog

D006439 Hemodynamics The movement and the forces involved in the movement of the blood through the CARDIOVASCULAR SYSTEM. Hemodynamic
D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
