A surgical pressure transducer is attached to a stiff-walled catheter and a small balloon is attached at is other end. The catheter is filled with saline using a small syringe to pressurize the system to 80 mm Hg. At t = 0 s, the balloon is popped,forcing a step change in pressure from 80 to 0 mm Hg. The time-based signal is recorded (Fig.9.16). From the data, the ringing period is measured to be 45.5 ms at second peak amplitude, y(0.0455)=5.152m V. Is this system suitable to measured physiological pressures that have frequency content up to 5 Hz? Static sensitivity, K=1 mV/mm Hg.
