Effect of hypercapnia on net filtration of fluid in the lungs of awake newborn lambs.


To study the effect of hypercapnia on net transvascular filtration of fluid in newborn lungs, we measured pulmonary arterial and left pressures and collected lung lymph from 11 awake 2-wk-old lambs as they spontaneously breathed a gas mixture rich in carbon dioxide. After a 2-h control period in air, the lambs breathed 8-11% carbon dioxide mixed with air… (More)
