Fast-responding flow-independent blood gas catheter for oxygen measurement.
Analytic expressions were derived for the response time, flow dependency, and signal-to-background ratio of blood gas catheters. These expressions were utilized to optimize the design of a new catheter. The catheter was tested in vitro and in vivo, and shown to be fast responding and practically flow independent, with an acceptable signal-to-background ratio.
