| Abstract: | ABSTRACT. A number of methods exist to measure neonatal blood pressure, one of which involves oscillometric principles. This method is the functional basis of the Dinamap 847 which has been studied for accuracy and reproductibility in 398 paired comparisons with direct arterial measurements in nine neonates. The correlation between the Dinamap and direct arterial pressure values were excellent, although for systolic blood pressure the Dinamap tends to underestimate by 2.4 ± 3.9 mm Hg. The present study has shown the Dinamap to be a clinically reliable instrument for measuring neonatal blood pressure. |
