Abstract
This paper presents preliminary sensor designs and reports initial test results for the implementation of real-time simultaneous oxygen saturation and blood pressure measurement. Closed-lumen catheter-type in-vivo sensing schemes incorporate a proven, well-established distal-tipped fiberoptic pressure sensor. Spectroscopic oxygen saturation determination is multiplexed with pressure sensing in a shared transceiver approach, and oxygen saturation sensitivity may be enhanced via synchronous pressure detection. Operating principles for pressure and oxygen saturation measurement are described, and various catheter side-port oxygen saturation sensor designs are explored. Experimental methods and results are presented, and sensor sensitivity is examined.
