1. A sensor cassette for use in measuring a compositional parameter of the blood of a patient comprising:

  • a housing adapted and sized to be located outside the body of the patient and having a fluid flow passage therethrough which is capable of receiving blood from the patient; and

    a sensing element located in said housing in or near said fluid flow passage for providing a signal in response to a compositional parameter of blood, said fluid flow passage at or near the location of said sensing element being at least 4.8 times as wide as its depth, the depth of said fluid flow passage extending directly outwardly from said sensing element and the wide direction of said fluid flow passage being substantially perpendicular to both the general direction of fluid flow in said fluid flow passage and to the depth of the fluid flow passage.
