How do compliance, resistance, and pulse rate influence arterial Doppler waveforms in an in vitro flow phantom?

Population

In vitro flow model using a pulsatile artificial heart, rubber or polyethylene tubes, a water tank, and a glass tube

Intervention

Multiple combinations of compliance, resistance, and pulse rate

Outcome

Spectral Doppler tracings including peak systolic velocity, minimum diastolic velocity, resistive index (RI), pulsatility index, early systolic acceleration time, and acceleration indexsurrogate

Resistance, compliance, and pulse rate independently influence arterial Doppler waveforms, including the pulsus tardus and parvus phenomenon, in an in vitro model.
