Blood pressure may be determined from a sensor-based monitoring device that non-invasively senses pressure pulses from an underlying artery. A user positions the sensor on the surface of an anatomical structure over the-artery, such as over the edge of the radius bone of the wrist, using an articulated placement guide. The placement guide has a predetermined shape that is generally conformable with the cross-section of the anatomical structure. As hold-down pressure is applied, pressure pulses are sensed by the sensor to produce data from which the blood pressure may be obtained. The articulated placement guide has a plurality of segments which are connected by articulation regions, and is capable of expanding significantly to fit a wide range of sizes of the anatomical structure on which the monitoring is being done. In this manner, a single articulated placement guide can accommodate a variety of different patients, from children to bariatric.
