BACKGROUND Although evaluation of cardiac output by the partial carbon dioxide rebreathing technique is as accurate as thermodilution techniques under controlled mechanical ventilation, it is less accurate at low tidal volume. It is not clear whether reduced accuracy is due to low tidal volume or low minute ventilation. The effect of spontaneous breathing on the accuracy of partial carbon dioxi...
PURPOSE OF REVIEW Despite its widespread use, the role of noninvasive home mechanical ventilation for the management of severe chronic obstructive pulmonary disease and chronic hypercapnic respiratory failure is still controversial. The majority of randomized controlled trials show methodological weaknesses, including issues of patient selection, insufficient pressure support and poor adherence...
BACKGROUND Post-operative pulmonary complications add to the morbidity and mortality of surgical patients, in particular after general anesthesia >2 hours for abdominal surgery. Whether a protective mechanical ventilation strategy with higher levels of positive end-expiratory pressure (PEEP) and repeated recruitment maneuvers; the "open lung strategy", protects against post-operative pulmonary ...
BACKGROUND Recent studies show that intraoperative mechanical ventilation using low tidal volumes (VT) can prevent postoperative pulmonary complications (PPCs). The aim of this individual patient data meta-analysis is to evaluate the individual associations between VT size and positive end-expiratory pressure (PEEP) level and occurrence of PPC. METHODS Randomized controlled trials comparing p...
