[Analytical reliability of the results of determining pH, pCO2 and pO2 with the ABL 300 (Radiometer) automatic pH and blood gas analyzer].
The analytical reliability of the determination of pH, pCO2 and pO2 by the automatic analyzer "ABL 300" (Radiometer) was studied. Control materials were used: Confirm, Acidbasol and Qualicheck in the normal, acid and alkaline sphere, and arterial blood, too. The precision within run and between runs for pH and pCO2 meets the contemporary standards (variation coefficient: pH--below 0.2%, pCO2--below 5%. The precision between runs for pO2 is unsatisfactory by low partial oxygen pressure. The accuracy of the three directly determined indices meets the contemporary standards. The comparative analysis of the results obtained by "ABL 300" and "Corning 178" shows a high degree of correlation between the two apparatuses.
