A multi-sensor support for in vivo monitoring of blood parameters with in situ sensor calibration.

An apparatus permitting continuous simultaneous in vivo monitoring of human arterial blood parameters is described. Sensors are held firmly in position in arterial blood flowing through an extracorporeal shunt. The system is reliable, rugged and inexpensive. Installation and manipulation are easy, and the sensors can be calibrated in situ. The system seems well suited for computer-aided monitoring of intensive care patients.
