Airway pressures change during fiberoptic bronchoscopy and endotracheal suctioning. In this study such pressure changes are examined in a mechanical lung model and in a population of ICU patients on mechanical ventilation. A systematic recording of airway pressures, tidal volumes and blood gases are carried out during ordinary therapeutic procedures requested by the staff physician. No additional study interventions are carried out.~The aim of the project is to examine negative effects of pressure/volume changes.
