Comparison of bicarbonate and base excess values analyzed by four different blood gas analyzers

Abstract

Comparison of the calculation formula, reproducibility, correlation and variation of bicarbonate ion concentration (HCO(3) (-)), and base excess value (BE) among four blood-gas analyzers was performed. No HCO(3) (-) and BE values calculated from the formulas showed any clinically significant difference, and all analyzers showed good correlation on their measurements. On the actual measurement of a specific sample, however, BE values from the same sample ranged between -6.3 and -15.7, which might affect therapeutic strategy. Caution should be taken for the assessment of data if different types of blood-gas analysis devices are used in the same facility.

“…1983). Arterial variables measured were pH, partial pressure of oxygen (PaO 2 ), partial pressure of carbon dioxide (PaCO 2 ), bicarbonate (HCO 3 − ) and base excess (BE) (Nakamaru et al. 2007).…”

Pyloric Stenosis and Nonbilious Vomiting in Infants: Negative Base Excess and Hypercapnia—Two Opposing Points of One Scale a Comparative Case Series

“…We used a quality-controlled commercial blood gas analyzer. It has been shown that different blood gas analyzers provide good reproducibility and correlation for standard bicarbonate, whereas the estimation of BE depends on the algorithm of estimation and type of analyzer [14] [15]. Finally, but not least in importance, we did not consider the powerful role of chloride anions.…”
