Accuracy of Pulse Oximeters With Profound Hypoxia At Rest (NIHO19)

Determination of SpO2 and PR Accuracy Specifications at Rest / Accuracy of Pulse Oximeters With Profound Hypoxia NIHO 19/ Pulse Oximeter Accuracy Evaluation Protocol

The aim of this study is to determine the accuracy of devices called pulse oximeters, which measure blood oxygen by shining light through fingers, ears or other skin, without requiring blood sampling. Study will be used with patients at rest.

This study is intended to evaluate performance of a new design pulse oximeter (test device) manufactured by Nihon Kohden Corporation sufficiently to support performance claims for an FDA 510K submission or ISO technical file. Specifically, SpO2 and pulse rate accuracy will be assessed for a Nihon Kohden OLV-4202 pulse oximeter with adult patients under a controlled setting of varying levels of inhaled oxygen concentration levels for patients at rest.
