<p>Described here are a novel means and device for noninvasively quantifying important blood constituents. Total hemoglobin, arterial oxygen content, hematocrit, and other parameters can all be determined quickly and easily without the need for skin puncture or lengthy laboratory analysis. The invention described here concerns the simultaneous measurement or control of volume changes and changes in the mass of either oxyhemoglobin, total hemoglobin, or reduced hemoglobin or other blood constituents such as glucose, bilirubin or cholesterol. The data obtained by these measurements is used to quantify the parameters of interest.</p> |
