WebIt is typically written in the following form: P ρ + V 2 2 +gz = constant (3.1) (3.1) P ρ + V 2 2 + g z = c o n s t a n t. The restrictions placed on the application of this equation are rather limiting, but still this form of the equation is very powerful and can be applied to a large number of applications. But since it is so restrictive ... WebDec 7, 2024 · Color flow Doppler is placed over the RVOT to detect flow acceleration or regurgitation. Then, using both continuous wave and pulse wave Doppler at the level of the pulmonary valve, velocities across the pulmonary valve in systole and diastole and peak velocities around the RVOT can be measured (figure 1 and image 1 and image 2). …
