During Intensive Care, Surgery 

Blood Gases Monitored Continuously  A new electrode system for the continuous measurement of blood gases has undergone successful clinical trial.The system measures pO2, pCO2, as well as pH and the temperature of blood flowing through a small extracorporeal loop.It was developed by Beckman Instruments Inc., Fullerton, Calif, and given laboratory and clinical trial at Loma Linda University School of Medicine, Loma Linda.In a report at the annual meeting of the Association for the Advancement of Medical Instrumentation, John E. Leonard, PhD, said the system can be used to monitor patients during surgery and in intensive care units.Dr. Leonard is manager of applied research for medical development at Beckman.Blood is directed through a Teflon flow chamber placed in the extracorporeal loop. During surgery, it can be connected to a heart-lung machine to monitor its performance. In an intensive care
