Abstract

A device and method for noninvasively quantifying important physiological parameters in blood. The device and method utilizes changes in molecular behavior induced by thermal energy of change to facilitate the measurement of the physiological parameters in blood. Oxygen saturation, partial pressure of oxygen, partial pressure of carbon dioxide, concentration of bicarbonate ion and total carbon dioxide, acid-base balance, base excess, hemoglobin level, hematocrit, oxyhemoglobin level, deoxyhemoglobin level, and oxygen content can all be determined quickly, easily, and continuously. There is no need for skin puncture or laboratory analysis.
