Work of breathing (WOB, acronym of: Work of Breathing) of a spontaneously breathing patient is measured as the area of the esophageal pressure volume loop.

Using the Campbell diagram can be decomposed the patient work of breathing in different areas that compose it. Resistive inspiratory, expiratory resistive, elastic, elastic autoPEEP associated with negative expiratory elastic and active.

The FluxMed monitor calculates the respiratory work and graph Diagram Campbell, in real time, breath by breath. Allowing to observe the actual work immediately of any change in their situation.
