In most patients having noncardiac surgery, blood pressure is measured using oscillometry via an upper arm cuff. Although the method is noninvasive and practical, it is known to overestimate intra-arterial pressure in hypotension and to underestimate it in hypertension. In this issue of Anesthesiology, Briegel et al. tested a new high-fidelity upper arm cuff incorporating a hydraulic sensor pad. In an accompanying Editorial, Saugel et al. discuss the performance and practicality of using this innovative new method for noninvasive intermittent blood pressure monitoring. Cover Illustration: A.
