Clinical Benefits of Blood Gas Testing in Critical Care: Amazing Stories

July 17, 2019

Webinar presented by Martha E Lyon PhD, DABCC, FACB Clinical Biochemist Royal University Hospital Saskatchewan Health Authority Saskatoon, Saskatchewan, Canada


About this webinar

In 1957, the first blood gas analyzer was developed and it was capable of measuring pH, pCO2 and pO2. Since then, significant technological advancements have enabled the implementation of low specimen volume test menus that include electrolytes, metabolites and hemoglobin derivations in addition to blood gases and pH. Blood gas analyzers are now routinely used to monitor challenging populations such as critically ill patients.  In this case based webinar, the benefits/limitations of monitoring critically ill patients in the clinical laboratory will be discussed and compared with the merits/limitations of blood gas analyzers.
