Summary

Background: Fiber bronchoscopy is a routine operation in intensive care unit (ICU), but it may cause local collapse of the lung. Recruitment maneuver (RM) after fiber bronchoscopy may have the potential to restore functional residual air volume and increase lung volume. However, there is still a lack of quantitative indicators to evaluate the effect of recruitment maneuver. With electrical impedance tomography (EIT), we can monitor lung ventilation in real time to understand the situation of lung ventilation.

Objective: To evaluate whether recruitment maneuver after fiber bronchoscopy can improve lung volume and improve lung ventilation, and which people are most likely to benefit from it, by monitoring the end expiratory pulmonary impedance of critically ill patients undergoing bedside fiber bronchoscopy to monitor the lung ventilation before and after the operation and before and after recruitment maneuver.

Study Design: A prospective observational study was conducted to monitor the end expiratory lung impedance (EELI), tidal impedance variable (TIV), global inhomogeneity (GI) index and Center of Ventilation (CoV) before and after bronchoscopy and recruitment maneuver, and then to understand the changes of lung volume and ventilation.
