OBJECTIVES During mechanical ventilation, air flows may play a role in mucus transport via two-phase gas liquid flow. The aim of this study was to evaluate effects of duty cycles and positive end-expiratory pressure on mucus clearance in pigs using mechanical ventilation, and to assess their safety. DESIGN Prospective randomized animal study. SETTING Animal research facility, University of ...
OBJECTIVE To compare the generation of continuous positive airway pressure using a hand-made device (underwater seal) or a ventilator (Inter 3). METHOD Two positive airway pressure generation systems were compared through laboratory simulations. Measurements were not considered if the mechanical ventilator required calibration or in the presence of gas flow variation (flowmeter sphere oscilla...
