There are three sources of error in the indirect measurement of blood pressure: (1) observer bias, (2) faulty equipment, and (3) failure to standardize the techniques of measurement. This article examines each area extensively, discusses the cumulative effect of these errors on the accuracy of indirect blood pressure measurement, and reviews the recommendations for proper indirect measurement of blood pressure.
