Analyzers, Laboratory, Blood Gas

Definition : Laboratory analyzers that measure concentrations of gases in samples of plasma, serum, or whole blood. These analyzers are used for measuring partial pressure of carbon dioxide (PCO2) and oxygen (PO2), usually in arterial whole blood specimens, using two different sets of electrodes. Some laboratory blood gas analyzers also calculate other parameters, such as oxygen total content (ctO2) and bicarbonate (HCO3-). They may also perform electrolyte and/or hematologic determinations (e.g., hematocrit). Blood gas analyzers are used to determine oxygen/carbon dioxide exchange in patient diagnosis and regulation of therapy.
