The wrong cuff size (shorter cuffs overestimate blood pressure, whereas larger ones underestimate it). Also,
aneroid instruments (used by 34% of practices) often go out of calibration, usually downward. In surveys,
one third of office devices were off by >10 mm. Hence, the need for periodical recalibration.
