Abstract
This invention relates to a method and apparatus for in-vivo, real time measurement of pH, pCO , base excess, hemoglobin, and hemoglobin oxygen saturation. Specifically, the invention relates to an apparatus placed in-line with an existing invasive patient access line to provide continuous, semi-continuous, or non-continuous monitoring of blood pH, pCO , base excess, hemoglobin, and hemoglobin oxygen saturation in a manner which is relatively non-invasive. Further, the device and apparatus allows monitoring of the listed parameters in a non-destructive manner such that the blood sample under analysis can be returned to the patient.
