Tho Automated Extmomponoal G"' Exchange Sy,tem (AEGES) control' the blood flow rate and/or the flow of gas to the oxygenator in order to meet user-defined setpoints for P02 and PC02 of blood drained from the patient while maintaining safe pressures in the CPB circuit and/or the patient's circulation. ...

Arterial blood gases (ABG), a clinical test that involves measurement of the pH of arterial blood and the amount of oxygen and carbon dioxide dissolved in arterial blood, is routinely used in the diagnosis and monitoring of predominantly critically/acutely ill patients being cared for in hospital emergency rooms and intensive care units. The test allows assessment of two related physiological f...

Prolonged or intermittent asphyxia in utero and during farrowing weakens piglets and renders them less capable of adaptation to extrauterine life. Piglets with lesser viability at birth have increased blood pCO2 and blood lactic acid concentrations and decreased blood pH. Moreover, the ability to thermoregulate during an acute cold stress is inversely related to umbilical blood lactate concentr...

The role of blood flow in absorption from the small gut would be best studied by a method able to measure exclusively blood flow in the small gut mucosa because this might vary independently of total small gut blood flow. Such a method should be repeatable to give values in control and experimental periods, and one would hope that it would be adaptable for use in man. We had hoped to meet these...

Typically, the standard practice for measuring the arterial blood carbon dioxide tension (PaCO2) during cardiopulmonary bypass (CPB) is to take intermittent blood samples for analysis by a bench blood gas analyzer. Continuous inline blood gas monitors are available but are expensive. A potential solution is the capnograph, which was evaluated by determining how accurately the carbon dioxide ten...
