OB Doppler: How, Why and When

Topics

• Indications/applications for performing OB Doppler
• Doppler waveform analysis and diagnostic criteria
• Factors that affect the Doppler assessment
• Doppler measurements; Doppler index, Resistive index, S/D ratio, Pulsatility index, velocity calculations
• Doppler evaluation of the middle cerebral artery, umbilical artery, Ductus venosus, umbilical vein, IVC, hepatic veins
