positive end expiratory pressure
Original Article Higher positive end expiratory pressure guided by upper inflection point of pressure volume curve ameliorating respiratory function in acute respiratory distress syndrome pig models
... Reduction of the tidal volume, and thus of the stress applied to the lungs, can protect the lungs from over inflation and unambiguously reduce acute respiratory distress syndrome (ARDS) mortality in a large multicenter ...

End expiratory lung volume during mechanical ventilation: a comparison with reference values and the effect of positive end expiratory pressure in intensive care unit patients with different lung conditions
... In critically ill patients receiving mechanical ventilation, FRC is determined by the level of positive end-expiratory pressure (PEEP), and it is therefore better to speak of EELV. Application ...

Effects of positive end expiratory pressure on gastric mucosal perfusion in acute respiratory distress syndrome
... Adult mechanically ventilated patients were considered eligi- ble for the study if they met the following criteria for ARDS dur- ing the 24 hours that preceded the study: acute onset of respiratory failure; diffuse ...

Effects of Alveolar Recruitment and Positive End Expiratory Pressure on Oxygenation during One Lung Ventilation in the Supine Position
... This study investigated the effects of AR with subsequent PEEP and PEEP alone on oxygenation during OLV in the supine position. We observed that bilateral lung recruitment before the start of OLV not only improved the ...

Detection of ‘best’ positive end expiratory pressure derived from electrical impedance tomography parameters during a decremental positive end expiratory pressure trial
... Using EITdiag software, we calculated the VSA. For this, the number of pixels with an EIT signal in the gen- erated ventilation distribution map was counted for both lung regions. During the recruitment maneuver, the ...
