Background Atelectasis is a common postoperative complication. Peri-operative lung protection can reduce atelectasis; however, it not clear whether this persists into the period. Objective To evaluate to what extent lung-protective ventilation reduces peri-operative atelectasis in children undergoing nonabdominal surgery. Design Randomised, controlled, double-blind study. Setting Single tertiar...

Positive end-expiratory pressure (PEEP) is an essential technique for the respiratory care of many critically ill patients who require ventilatory support. With the application of PEEP, the baseline end-expiratory pressure in mechanically ventilated patients is elevated above atmospheric pressure. In general, the application of PEEP is expected to improve lung mechanics and gas exchange as it r...

Three types of positive pressure breathing have been differentiated : a) continuous positive pressure breathing where a pressure above atmospheric is maintained in the lungs throughout the respiratory cycle, b) expiratory positive pressure breathing in which a pressure above atmospheric is present during the expiratory phase of breathing, and c) intermittent positive pressure breathing (IPPB), ...

OBJECTIVE To determine whether regional hypoperfusion of the interventricular septum occurs during ventilation with positive end-expiratory pressure. DESIGN Animal study. ANIMALS Anesthetized, closed chest dogs (n = 8). INTERVENTIONS Induction of experimental adult respiratory distress syndrome (ARDS) and then ventilation with 10, 15, and 20 cm H2O of positive end-expiratory pressure. M...

An empirical study was undertaken in San Diego, California, to test assumptions made by the government and by conservative religious policy advocates that there is a greater incidence of crime in the vicinity of peep show establishments. We asked two questions: (a) Is criminal activity in San Diego particularly acute at peep show establishments compared to surrounding control locations? and (b)...

INTRODUCTION The increase in the number of studies has led to greater security in the application of this method and the determination of its effectiveness in adults.. The purpose of the present study was to evaluate heart rate variability in healthy individuals submitted to different levels of positive expiratory pressure using an expiratory positive airway pressure (EPAP) device. MATERIAL A...
