Flow volume loop obstructive lung disease

WebThe lung is then slowly filled with air and the change in lung size (volume) is measured and recorded on the Y-axis. The X-axis records the “airway pressure” or pressure build up in the airways of the lung as the air is pumped in. In a normal lung, the pressure-volume curve will resemble the green tracing below.
