WebIt is used to assess ventricular in-flow patterns, intracardiac shunts, and to make precise measurements of blood flow at valve orifices. Color-flow mapping CFM uses measurements of the velocity and direction of blood flow to superimpose a color pattern onto a section of a 2D image (see Figure 4 ).

WebOct 29, 2024 · The A-a gradient subtracts the PaO 2 from the result of the Alveolar Gas Equation (PAO 2):. PAO 2 – PaO 2 = P(A-a)O 2 (mmHg). The PAO 2 calculation is an estimated value using the following equation:. PAO2 = FiO 2 (PB-PH 2 O) – PaCO 2 /RQ. FiO 2 = concentration of oxygen the patient is breathing.
