Clinically Proven Accuracy and Performance in Challenging Conditions
Nonin Medical actively works with independent review and testing labs to ensure optimal performance of its monitoring devices. We welcome you to review the clinical evidence of our proven performance in the most challenging conditions and environments.
The following study was presented as a podium presentation by Dr. David B. MacLeod, FRCA, at the 2009 American Society of Anesthesiologists (ASA) Annual Meeting.
Calibration and Validation of the Nonin Non-invasive Regional Oximeter with Cerebral Sensor -David B. MacLeod, F.R.C.A., Department of Anesthesiology, Duke University Medical Center
Recently near infra-red spectroscopy (NIRS) regional oximeters have been developed to noninvasively estimate cerebral tissue oxygen saturation. This measure represents the oxygen level within brain tissue and is a composite value based on the relative proportions of arterial and venous blood within the tissue. Unlike conventional pulse oximetry, NIRS cerebral oximetry does not rely on a pulsating flow and therefore is able to provide a reading during non-pulsating flow such as CPB.
A prospective two-phase clinical study in healthy, adult subjects was conducted to calibrate and validate a new NIRS regional oximeter with a cerebral sensor to determine the accuracy in measuring cerebral oxygen saturation.
