Abstract :
Research undertaken to investigate the characteristics of typical catheter-transducer systems to determine how frequency-dependent resistance and damping values can affect the reproductive fidelity of direct arterial pressure recordings is discussed. While the data presented will not cause methods and techniques used in invasive pressure monitoring to be altered appreciably, they will explain some of the anomalies reported in predicting system damping from measurable system parameters, and may aid in the selection of optimal components for accurate recording of blood pressure.<>
