WebAlign cursor with blood flow, use color flow Doppler for accuracy. Place sample volume 1 cm into the pulmonary vein from the opening into the right atrium. Use PW Doppler and record spectral doppler. Using the preset measurements under ‘Analysis’ measure: Peak S velocity. Peak D velocity. Peak AR velocity. AR wave duration. WebA typical PW Doppler velocity consists of a spec-tral recording of varying intensity,depending on the acoustic density of the reflected interface, ie, the mass of blood cells (Figure …
