WebTwo mechanisms may be responsible for the changes in compliance. First, varying TV or PEEP will alter the position of tidal ventilation on the pressure-volume curve, resulting in an increase in compliance with increasing TV and PEEP up to a point, where overdistention occurs and compliance decreases. WebJan 1, 2000 · PEEP increased dead space/tidal volume ratio 36%; restoration of cardiac output reduced dead space/tidal volume ratio only 7% and did not return alveolar capillary perfusion to baseline levels.

"WebTidal Volume. Tidal volume is a measure of the amount of air a person inhales during a normal breath. Traditional preset tidal volumes higher than 10 ml/kg have been proved to be associated with increased risk of pulmonary barotrauma and should be avoided. High tidal volumes also decrease venous return and reduce cardiac output. " - How does peep affect tidal volume

Webtidal volume and PEEP were associated with survival only through concomitant changes in driving pressure [16]. 4.3.5 Esophageal Pessurr e. During mechanical ventilation, the airway pressure attempts to distend the lung, while the pleural pressure acts as a counterforce in the opposite direction. Thus the WebCommon reasons for increased plateau pressures are the use of high PEEP, inspiratory flow, and tidal volume. Adverse consequences of high plateau pressures are barotrauma, …
