Abstract
Automated brachial cuffs are used to monitor arterial pressure (AP) in most anesthetized patients. Commonly inflating at regular intervals of 3–5 minutes, these devices only provide an intermittent monitoring, and may miss rapid hypotensive or hypertensive events. We investigated the ability of our oBPM® algorithm in detecting such changes in AP in 40 patients undergoing general anesthesia from pulse oximeter photoplethysmographic signals. The results demonstrated good trending ability in detecting rapid changes for both systolic and mean AP. Implemented in clinical settings, this solution may help in decreasing the duration of intraoperative hypo-/hypertensive events, thereby improving clinical outcome.
