Breathing moves volumes of electrically insulating air into and out of the lungs, producing
conductivity changes which can be seen by electrical impedance tomography (EIT). It has thus …

Alveolar overdistention and cyclic reopening of collapsed alveoli have been implicated in
the lung damage found in animals submitted to artificial ventilation. To test whether these …

Introduction Noninvasive ventilation (NIV), as a weaning-facilitating strategy in predominantly
chronic obstructive pulmonary disease (COPD) mechanically ventilated patients, is …

BACKGROUND: Retention of airway secretions is a common and serious problem in
ventilated patients. Treating or avoiding secretion retention with mucus thinning, patient-positioning…

This study tests the hypotheses that a recruitment maneuver per se yields and/or intensifies
lung mechanical stress. Recruitment maneuver was applied to a model of paraquat-induced …

In the experimental setting, repeated derecruitments of the lungs of ARDS models accentuate
lung injury during mechanical ventilation, whereas open lung concept strategies can …

Accomplishing the lung’s primary function of gas exchange requires close contact between
gas and blood across the extensive alveolar surface. Because of non-uniform regional and …

Purpose Clinical applications of quantitative computed tomography (qCT) in patients with
pulmonary opacifications are hindered by the radiation exposure and by the arduous manual …

Very few cases of pulmonary vasculitis that cannot be classified into a single category of
vasculitis have been described. We report the first case of a vasculitic process in which …

Patients under pressure support ventilation sometimes encounter patient-ventilator asynchrony
in the transition from inspiration to expiration, that is, expiratory asynchrony. This problem …
