WebThe changes in lung volume that occur with changes in pressure can be plotted as a pressure-volume curve. The slope of the line is known as compliance. Compliance has an effect on ventilation and causes air to be unevenly distributed. Low compliance indicates a stiff lung and means that more work is required to bring in a normal amount of air. hellosarangWeb1 dec. 2012 · So the misconception isn’t that a plethysmograph can measure “trapped air”, it’s that it can measure it accurately.
