Red/above baseline = flow towards the US beam
Blue/below baseline = flow away from the US beam
Focused echocardiography:
IVC – aorta anatomic correlation 
Applicable to isolated IVC POCUS 
Measuring accurate cardiac output: Use zoomed PLAX view to measure LVOT diameter and ensure correct Doppler settings 
Shape of the right ventricular outflow Doppler envelope can predict the severity of pulmonary hypertension. 
Ratio of the echocardiographic surrogates of pulmonary artery pressure and left atrial pressure.

Diastolic dysfunction
Diastolic function in combination with volume status determines LV filling pressures, which when elevated
cause the cardinal symptoms of heart failure. Parameters commonly measured to assess different aspects of LV filling pressures are indicated in brown.
