Another Look at Noninvasive Continuous Arterial Pressure Monitoring

Abstract

The Nexfin is a noninvasive finger-cuff device that uses photoplethysmographic technology to continuously measure arterial pressure. To compare Nexfin measurements to intra-arterial pressure (IAP) measured by ipsilateral radial artery catheterization, researchers recorded blood pressures (BPs) with both methods every 5 seconds during induction of elective anesthesia in 31 adults. A total of 3479 paired measurements were …
