Abstract :
Pressure recording is frequently performed with catheter-manometer systems having high frequency response but inadequate damping. Resonance amplification of catheter movement artefact is often a problem with underdamped systems. The amount of amplitude amplification at the resonant frequency of a water-filled catheter and transducer is a function of the damping of the system.
