Pulsatile prosthetic valve flows.

Transactions - American Society for Artificial Internal Organs, 1981
The laser Doppler system has been established as a useful tool for eliciting the properties of simulated cardiovascular flows, and thus for comparative studies of flow properties of prosthetic valves. Significant differences among valve types and between models of one type have been documented. The complex variations of velocity profiles with time show

Pulsatile Flow Pulmonary Hemodynamics

1991
of only mean pulmonary artery pressure (Ppa) and mean pulmonary blood flow (Q). Accordingly, the functional state of the pulmonary circulation still is currently evaluated by pulmonary vascular resistance (PVR) calculated as a mean pressure/mean flow ratio.

Pulsatile flow in a catheterised artery

Journal of Biomechanics, 1986
A model is presented for the physiological problem of a catheter which is inserted in a femoral artery to measure the pressure gradient. As the catheter will modify the pressure distribution in the artery, the pressure gradient which would be recorded by a perfect pressure transducer attached to it would differ from that in the uncatheterised artery ...

Elastic effects in pulsatile blood flow

Microvascular Research, 1975
Abstract The persistence of pulsation into the microcirculation raises questions concerning the roles of the steady and oscillatory pressure components in determining blood flow. To resolve these questions, measurements have been made on precisely controlled flows in small, rigid tubes. Principal measurements are with 46% hematocrit human blood in an
