Objective To study the differences in blood pressure readings between the auscultatory and oscillometric (Dinamap model 8100; Critikon, Tampa, Fla) methods. Design Survey of 2 blood pressure instruments. Setting Public schools. Participants Seven thousand two hundred eight schoolchildren aged 5 through 17 years. Main Outcome Measure Blood pressure levels. Results For all children combined , Dinamap systolic pressure readings were 10 mm Hg higher (95% confidence interval, −4 to 24 mm Hg) than the auscultatory systolic pressure readings. Dinamap diastolic pressure readings were 5 mm Hg higher (95% confidence interval, −14 to 23 mm Hg) than the auscultatory Korotkoff phase V diastolic pressure readings. Conclusion These findings preclude the interchange of readings by the 2 methods. Caution must be exercised in the diagnosis of hypertension when an automated device is used.
