Continuity Equation​

For conduits in series ("in continuity"), volume flow is​

equal: A1*V1 = A2*V2. where V is the velocity.​

125213​ Continuity Equation by Mean​

For conduits in series ("in continuity"), volume flow is​

Velocity​

equal: A1*V1 = A2*V2. where V is the mean velocity.​

125214​ Continuity Equation by Peak​

For conduits in series ("in continuity"), volume flow is​

Velocity​

equal: A1*V1 = A2*V2. where V is the peak velocity.​

Time Integral​

equal: A1*V1 = A2*V2. where V is the velocity time​

integral.​

125216​

Proximal Isovelocity Surface​

Utilizes aliasing velocity (by color Doppler) of flow into​

Area​

an orifice (often regurgitant or stenotic) to measure​

instantaneous flow rate, orifice area, and flow volume.​

Theinstantaneousflowrate=(2πr2vav )*(απ)wherevav​

is the constant velocity known as aliasing velocity at​

radius r, vp is the peak velocity at the orifice, and α is the​

angle in radians of the constant velocity surface.​

Estimated Orifice area = Flow rate / vp , where vp

is the​

peak velocity at the orifice and the flow rate is the PISA​

peak flow rate.​

The volume flow is then the product of the orifice area​

and Velocity Time Integral.​
