Pressure-controlled ventilation and intrabronchial pressure during one-lung ventilation.
BACKGROUND Pressure-controlled ventilation (PCV) has been suggested to reduce peak airway pressure (P(peak)) and intrapulmonary shunt during one-lung ventilation (OLV) when compared with volume-controlled ventilation (VCV). At the same tidal volume (V(T)), the apparent difference in P(peak) is mainly related to the presence of a double-lumen tracheal tube. We tested the hypothesis that the decr...
متن کاملIndependent Lung Ventilation and One Lung Ventilation
The application of the independent lung ventilation (ILV) in adults has been described by Carlon and co-workers in 1978 and subsequently by other investigators. In 1983 Hedenstierna and coworkers using a bilumen tube suitable for prolonged intubation, and two Servo Ventilator 900 B (Siemens) adapted for synchronization, treated a wide range of clinical conditions. Following this experience, the...
متن کاملTime course changes of oxidative stress and inflammation in hyperoxia-induced acute lung injury in rats
Objective(s):Therapies with high levels of oxygen are commonly used in the management of critical care. However, prolonged exposure to hyperoxia can cause acute lung injury. Although oxidative stress and inflammation are purported to play an important role in the pathogenesis of acute lung injury, the exact mechanisms are still less known in the hyperoxic acute lung injury (HALI). Materials ...
متن کاملThe use of air in the inspired gas mixture during two-lung ventilation delays lung collapse during one-lung ventilation.
BACKGROUND Collapse of the ipsilateral lung facilitates surgical exposure during thoracic procedures. The use of different gas mixtures during two-lung ventilation (2LV) may improve or impede surgical conditions during subsequent one-lung ventilation (OLV) by increasing or delaying lung collapse. We investigated the effects of three different gas mixtures during 2LV on lung collapse and oxygena...
متن کاملOxygenation, inflammatory response and lung injury during one lung ventilation in rabbits using inspired oxygen fraction of 0.6 vs. 1.0
Maintaining adequate oxygenation during one-lung ventilation (OLV) requires high inspired oxygen fraction (FiO2). However, high FiO2 also causes inflammatory response and lung injury. Therefore, it remains a great interest to clinicians and scientists to optimize the care of patients undergoing OLV. The aim of this study was to determine and compare oxygenation, inflammatory response and lung i...
