Abstract
A method and apparatus for accurately determining a blood parameter that is calculated by measuring the transmittance of light through tissue having blood flowing therein is disclosed. A plurality of transmittance of light measurements are obtained for each transmittance of light parameter. The arithmetic mean of each transmittance of light parameter is calculated from the plurality of measurements. The arithmetic means are used to calculate the blood parameter from known formulations.
