WebFlow velocity across the mitral valve is examined in the apical four-chamber view (A4C) using pulsed Doppler. The sample volume (SV) should be placed between the leaflet tips (1–3 mm axial length of SV) and sweep speed is set to 50 mm/s to 100 mm/s (Figure 1). Gain and filter should be minimized in order to obtain optimal images. WebWhereas a stationary gas can be described by three variables ( pressure, temperature, adiabatic index ), and a moving gas by four ( flow velocity ), a hot gas in chemical equilibrium also requires state equations for the chemical components of the gas, and a gas in nonequilibrium solves those state equations using time as an extra variable.
