“…Previous workers have generally found a good agreement between the pressure where Korotkow sounds disappear entirely and the correct diastolic pressure. Results similar to those presenft'ed here were, however, obtained by Ragan and Bordley (9) and Berlliner et al (2). An acceptable explanation for the errors in estimating the diastolic pressure cannot be given.…”

“…A polythene tube (PE 160, 44 cm long) was inserted into one brachial artery, usually the left, using the percotaneous technique describcd by BernCus et al, 1954, (2). The left arm was used whenever possible, to diminish the discomfort afmter the arterial puncture.…”

“…Methodologic differences in ABP definition would affect SBP and DBP more than MBP. Regardless of the method used to identify arterial blood pressure, the range of measurement errors reported with single IBP measurements is large, usually being comparable to those in Table 5 [2,6,10,12,23,27,31,34,38,[40][41][42].…”

“…Respiratory variation in arterial SBP seldom exceeded 5 mm Hg (less for MBP and DBP), perhaps because intravascular volume was closely monitored and aggressively treated. Some studies have biased the direction of measurement error by selecting either end-expiratory or highest SBP for comparison [12,30,40]. Simultaneous IBP and ABP values have been obtained in some studies by using opposite arms.…”

In 38 adults undergoing cardiac surgery, 4 indirect blood pressure techniques were compared with brachial arterial blood pressure at predetermined intervals before and after cardiopulmonary bypass. Indirect blood pressure measurement techniques included automated oscillometry, manual auscultation, visual onset of oscillation (flicker) and return-to-flow methods. Hemodynamic measurements or calculations included heart rate, cardiac index, stroke volume index, and systemic vascular resistance index. Indirect and intraarterial blood pressure values were compared by simple linear regression by patient and measurement period. Measurement errors (arterial minus indirect blood pressure) were calculated, and stepwise regression assessed the relationship between measurement error and heart rate, cardiac index, stroke volume index, and systemic vascular resistance index. Indirect to intraarterial blood pressure correlation coefficients varied over time, with the strongest correlations often occurring at the first and last measurement periods (preinduction and 60 minutes after cardiopulmonary bypass), particularly for systolic blood pressure. Within-patient correlations between indirect and arterial blood pressure varied widely--they were consistently high or low in some patients. In other patients, correlations were especially weak with a particular indirect blood pressure method for systolic, mean, or diastolic blood pressure; in some cases indirect blood pressure was inadequate for clinical diagnosis of acute blood pressure changes or trends. The mean correlations between indirect and direct blood pressure values were, for systolic blood pressure: 0.69 for oscillometry, 0.77 for auscultation, 0.73 for flicker, and 0.74 for return-to-flow; for mean blood pressure: 0.70 for oscillometry and 0.73 for auscultation; and for diastolic blood pressure: 0.73 for oscillometry and 0.69 for auscultation. The mean measurement errors (arterial minus indirect values) for the individual indirect blood pressure methods were, for systolic: 0 mm Hg for oscillometry, 9 mm Hg for auscultation, -5 mm Hg for flicker, 7 mm Hg for return-to-flow; for mean: -6 mm Hg for oscillometry, and -3 mm Hg for auscultation; and for diastolic: -9 mm Hg for oscillometry and -8 mm Hg for auscultation. Mean measurement error for systolic blood pressure was thus least with automated oscillometry and greatest with manual auscultation, while standard deviations ranging from 9 to 15 mm Hg confirmed the highly variable nature of single indirect blood pressure measurements. Except for oscillometric diastolic blood pressure, a combination of systemic hemodynamics (heart rate, stroke volume index, systemic vascular resistance index, and cardiac index) correlated with each indirect blood pressure measurement error, which suggests that particular numeric ranges of these variables minimize measurement error.(ABSTRACT TRUNCATED AT 400 WORDS)
