Can a Light-Guided device make arterial sticks easier?

This study tests whether a new device called Blood'up can help locate the radial artery in the wrist better than the traditional method of feeling for the pulse. Healthy volunteers will have arterial blood samples taken from both wrists, one using the device and the other using manual palpation, to compare success rates. The study also includes a group where low blood pressure is simulated with a blood pressure cuff, to see if the device helps when the pulse is harder to feel. The goal is to see if this technology could reduce the number of needle sticks needed and improve patient comfort.
