Title :
Measuring the characteristics of pressure transducers

Abstract :
Summary form only given. Physiological pressure measurements can be made using a number of different techniques, the most popular of which are: the catheter-tip micro transducer; a liquid filled catheter-transducer; and an air filled balloon-catheter-transducer system. The latter two techniques involve the transducer being connected to the site of pressure measurement by the catheter. The complete measuring system also contains signal processing electronics and usually some form of recording device. Two methods by which the behaviour can be quantified are considered: measuring the response to a rapid change in pressure; and measuring the response to a sinusoidally varying pressure
