Accuracy of radial arterial pressure measurement during surgery under controlled hypotension

Background: Radial arterial pressure underestimates the pressure in the aorta in several clinical situations. A central‐to‐radial pressure gradient was attributed to intense vasodilation. The aim of this study was to evaluate the accuracy of radial pressure monitoring during controlled hypotension achieved with profound arterial vasodilation.
