Fig. 3From: Noninvasive assessment of airflows by electrical impedance tomography in intubated hypoxemic patients: an exploratory studyLower levels of pressure support improved homogeneity of regional maximal flow distribution both during inspiration and expiration in comparison with higher support (PSVlow vs. PSVhigh) (a); higher positive end-expiratory pressure level led to an improvement in maximal inspiratory and expiratory flows (MIF and MEF) homogeneity both during pressure support ventilation (PSV-PEEPhigh vs. PSV-PEEPlow) (b) and volume-controlled ventilation (VCV-PEEPhigh vs. VCV-PEEPlow); (c) dashed line represents perfect homogeneityBack to article page
