Cuff measurements may underestimate SBP at higher levels; leaves open whether mean BP offers more consistent accuracy across ranges.
Does indirect auscultatory blood pressure measurement accurately reflect direct intrabrachial blood pressure in normotensive and hypertensive subjects?
Auscultatory blood pressure underestimates systolic pressure at higher levels compared to direct intrabrachial measurement, suggesting mean blood pressure may be a more consistent metric across BP ranges.
Fagher et al. (1994) studied this question.
