Description

This lecture covers the direct measurement of arterial pressure using resistive sensors. It explains the process of measuring arterial blood pressure through lead II voltage, differentiating between systolic and diastolic pressure. The lecture also discusses extravascular and intravascular sensors, their response times, and the use of catheters filled with liquid. Additionally, it delves into the dynamic properties of pressure measurement systems, modeling the catheter-liquid-membrane system, and the analogies between hydraulic and electrical systems. The lecture concludes with examples of piezoresistive structures and the frequency range of extravascular sensors.
