Fig. 2From: The effects of pressure- versus volume-controlled ventilation on ventilator work of breathingPartitioning of resistive MW of the ventilator (cmH2O.L) applied due to different components of the respiratory system assuming a square profile with VT = 0.5 L and the reference condition for both normal subjects and COPDs. The work exerted to the ETT and lung airways is the major components of the resistive MW in normals and COPDs, respectivelyBack to article page
