Abstract
BackgroundOscillatory positive expiratory pressure (OPEP) devices are airway clearance tools generating positive pressure, yet evidence supporting their efficacy post-surgery for lung recruitment and gas distribution is limited. ObjectivesInvestigate OPEP's impact on lung recruitment and gas distribution using Electrical impedance tomography (EIT) in post-surgery patients. Methods26 ICU-extubated patients post-major surgery used OPEP at five levels with EIT monitoring. Primary outcome: change in end-expiratory lung impedance (ΔEELI) post-OPEP; secondary outcomes: global inhomogeneity index (GI), respiratory rate, oxygen saturation, blood pressure, and heart rate. ResultsSignificant ΔEELI increase during OPEP versus baseline, correlating with OPEP level. ROI3 (mid-dorsal lung) exhibited highest ΔEELI. Oxygen saturation improved post-OPEP. ConclusionsOPEP effectively increased end-expiratory lung volume post-major surgery, notably in mid-dorsal regions, enhancing short-term oxygenation.
