FRC = functional residual capacity. A modified version of the Campbell diagram to measure the work of breathing (WOB) of a spontaneously breathing, intubated patient is constructed by plotting the intraesophageal pressure (Pes), an approximation of intrapleural pressure on the x-axis and change in tidal volume (VT), expressed as a percentage of vital capacity on the y-axis. The compliance of the chest wall (CCW) and lung (CL) are shown as dotted lines. Elastic work is the triangular area labelled ‘E’ and imposed work is labeled ‘I’. From Reference 12.
