Figure 5

80–140 mmHg pressure waveforms generated in water with a Bio-Tek 601A pressure simulator and measured by an FOP-M260 pressure sensor connected to a 15 kHz FPI-HS interrogator from FISO Technologies. Acquisition rate is set to 3 kHz, and lowpass filter is set to 30 Hz, 300 Hz, and 3000 Hz. (a) Normal aorta waveform, 90 bpm. (b) 0.5 Hz square waveform. Graphs have an offset for better clarity. (c) Detail of previous graph with graphs offset for better clarity to show an increasing pressure impulse.
