(57) [Summary] (Modified) [Purpose] Five blood gas parameters (ie pH, PO 2 , PCO 2 , [HCO] 3 -], and O 2 provides a method and apparatus for measuring in the human body at least two saturation). [Configuration] human five blood gas parameters (i.e., pH, [HCO 3 -] , PCO 2, PO 2, and O At least two of the 2 saturation), a non-invasive to a method for measuring in vivo, utilizing at least one algorithm and at least one calibration model, the unknown of blood-containing tissue A non-invasive in vivo blood gas parameter measurement method comprising the step of calculating the value of a blood gas parameter from the intensity change measured from the tissue using two or more variables. |
