To facilitate the calculation of the transit time between physiological waveforms, (pressure, velocity, area, flow), this software offers four algorithms which can be applied to clinical/synthetic data. Continuous waveform data, along with the selection of the desired algorithm is applied to this function, and the transit times of each of the waveforms is provided.
