Abstract
A sensor cassette for use in measuring a compositional parameter of blood comprising a housing having a wall defining a passage which is adapted to receive blood. The wall is at least somewhat permeable to the compositional parameter. A support element, which is less permeable to the compositional parameter of blood than the housing, is carried by a region of the wall. A sensor is carried by the support element and provides a signal in response to the compositional parameter. The support element separates the sensor from at least a portion of such region of the wall so that the affect of the permeability of the housing to the compositional parameter on the signal from the sensor is reduced.
