Home health-care: accuracy, calibration, exhaust, and failure rate comparisons of digital blood pressure monitors.
This study provides a detailed comparison of 22 digital, blood pressure monitors intended for home use. Blood pressure and pulse-rate readings from each electronic monitor were compared with concurrent measures obtained using the mercury column and auscultation. Correlation coefficients and linear regressions were performed to evaluate accuracy. Separate analyses of variance were used to determine significant calibration errors for each model. The results showed considerable disparity among available home monitors under controlled testing conditions. Variables associated with accuracy and home use by the layperson are discussed.
