Abstract
An apparatus is disclosed for determining validity of a measured in-blood percentage of oxygenated hemoglobin. The apparatus has multiple pulse oximetry channels having at least three light sources of at least three distinct wavelengths, which are detected and converted to digital signals. The light sources are selectively activated, and two or more estimated in-blood percentages of oxygenated hemoglobin are calculated. It is determined whether a signal quality associated with the calculated in-blood percentages exceeds a predetermined accuracy threshold, and an associated validity indication is provided.
