Evolution of Blood Gas Testing Session 2: Acid-Base Balance and the Practical Applications of the Acid-Base Chart

Blood gas testing has improved over the years thanks to advances in technology. 60 years ago, blood gas testing meant determining pO2, pCO2 and pH levels. What is blood gas testing today? This series of webinars will investigate current assessment and diagnostic methods like co-oximetry and lactate measurement to more precisely assess a patient’s ability to utilize oxygen.

Session 1 reviewed the practical applications of the acid-base chart as an indicator to distinguish between metabolic vs respiratory disturbances. It will also identify the terminology, causes, and symptoms of acid-base imbalance. The session will review the importance of base excess for in-depth analysis of metabolic versus respiratory imbalance, and analyze the acid base chart and its application in interpreting the acid-base status.

Session 2 will provide a more in-depth look at the ability of today’s blood gas testing to determine the cause of reduced oxygen transport and release to tissues.
