ABSTRACT
Laboratory-based blood gas analyzers have reliably produced pH, PCO2, and PO2 analyses for several decades. Over this time, their design changes reduced maintenance procedures, microprocessor-controlled functions simplified operation, and regulations governing their use have expanded. This article presents the electrochemical principles of the pH and blood gas electrodes and the operational procedures necessary to satisfy regulatory standards.
