Abstract

Although minor systematic variations between the results of BLOOD GAS ANALYZERs are inevitable; they seem not to have any adverse clinical effect due to their being trivial. In this study we tried to show the clinical significance of these minor systematic variations.Sixty-eight patients in Shariati Hospital were studied. Their arterial blood samples were analyzed simultaneously by two BLOOD GAS ANALYZERs available at Shariati Hospital and the results were compared. The mean of differences for pH, P02 and Pea2 were respectively 0.051, 1.122 and 2.734 mm Hg. The differences of pH and Pc02 were significantly different from zero (P =0.000001). The clinical study showed 9% discrepancies in diagnoses of respiratory disorders and 26.5% discrepancies in diagnoses of acid base disorders. All the respiratory disorder discrepancies were located in the range of 58-90 mm Hg for P02 (p =0.013). And the majority of acid base discrepancies were located in a special range of pH (7.306-7.466) and Pea2 (25.6-39.1) (P=0.000005).This study proved that minor systematic errors in BLOOD GAS ANALYZERs could affect clinical judgement specially if the results are found to be in a particular range are clinically significant.
