Respiratory Gas Tensions Of Thoracic Duct Lymph

Abstract
Samples of thoracic duct lymph from dogs and patients were analyzed for PO2 [O2 pressure], PCO2 [CO2pressure] and pH under experimental conditions that were varied by altering pH, splanchnic blood flow, splanchnic O2 consumption and the PO2 of inspired air. Evidence was obtained which indicated that changes in gas tensions of thoracic duct lymph provide direct information concerning alterations in gas exchange in splanchnic tissues. This technic may be useful in studying some of the poorly understood problems of tissue oxygenation in hemorrhagic shock, cirrhosis and congestive heart failure.
