From: Modeling ventilation of patients with interstitial lung disease at rest and exercise: a bench study
Ventilatory (A) and respiratory flow (B) behavior of the model with two compartments symmetrical or asymmetrical, moderate ILD profile at rest TV: tidal volume, EELV: end-expiratory lung volume, PEEP tot: total positive end-expiratory pressure, ΔP: driving pressure, ΔPtp: driving transcompartmental pressure, Strain: compartmental strain, MP: mechanical power, WOB: work of breathing, ILD: interstitial lung disease. 50/50: mild ILD profile with C1 = C2 = 50%*Cglob, 70/30: mild ILD profile with C1 = 70%Cglob and C2 = 30%Cglob, 90/10 mild ILD profile with C1 = 90%Cglob and C2 = 10%Cglob. In the 50/50 condition, the flow curves of compartments 1 and 2 are superimposed because the compliances and resistances are equal. Values are presented as mean. These simulated data have zero variance
