This protocol is a request from Masimo to assist in the collection of data to be used to further refine the accuracy of the monitor's algorithm.
Prospective Observational Study Characterizing Noninvasive Hemoglobin (SpHb) Measured With Pulse CO-Oximetry Technology in a Variety of Surgical Cases
The specific aim of this study is to collect data to characterize Masimo's noninvasive Rainbow SpHb technology during surgeries. The purpose is to compare Masimo Rainbow technology to arterial blood samples taken during surgery. Hemoglobin concentrations in the arterial blood samples will be measured using standard blood analyzers on site and/or the sponsor's laboratory.
