Automated office blood pressure (AOBP) measurement reduces human error and improves precision. Guidelines recommend that patients rest for 5 minutes before AOBP measurement and that 3 measurements be spaced at 1- to 2-minute intervals (Hypertension 2018; 71:e13). However, these guidelines are based on limited evidence, and following them is time consuming. In two studies, researchers assessed the effects of different rest-period durations before AOBP measurements and different intervals between measurements.
Baltimore researchers compared the effects of 2 minutes of rest or no rest (vs. the recommended 5 minutes of rest) before AOBP measurements in 113 adults. During a single visit, each participant underwent four sets of three AOBP measurem…
