Abstract
An electrical model of the human pulmonary arterial tree has been developed using modern oscillatory flow theory. By comparison with corresponding in vivo measurements of 1) pressure and flow waveshapes, 2) input impedance, and 3) apparent phase velocity, this passive, multisegmental, linear delay line model is shown to bear a close resemblance to reality.
