WebThe diffusing capacity for carbon monoxide (DLCO) is a measure of the ability of gas to transfer from the alveoli across the alveolar epithelium and the capillary endothelium to the red blood cells. The DLCO depends not only on the area and thickness of the blood-gas barrier but also on the volume of blood in the pulmonary capillaries. WebMitral Valve. Aortic Valve Mean Gradient. Normal Area 4.0-6.0 cm2. Mild Stenosis 1.5-2.5 cm2. Moderate Stenosis 1.5-1.5 cm2. Severe Stenosis < 1.0 cm2. Normal Gradient < 5 mmHg. Mild Stenosis 5-25 mmHg. Moderate Stenosis 25-50 mmHg.
