Brief Summary:
Conventional continuous mandatory mechanical ventilation relies on the passive recoil of the chest wall for expiration This results in an exponentially decreasing expiratory flow
Flow controlled ventilation FCV a new ventilation mode with constant continuous controlled expiratory flow has recently become clinically available and is increasingly being adopted for complex mechanical ventilation during surgery
In both clinical and pre-clinical settings an improvement in ventilation CO2 clearance has been observed during FCV compared to conventional ventilation Recently Schranc et al compared flow-controlled ventilation with pressure-regulated volume control in both double lung ventilation and one-lung ventilation in pigs They report differences in dead space ventilation that may explain the improved CO2 clearance although their study was not designed to compare dead space ventilation within the group of double lung ventilation
Dead space ventilation or wasted ventilation is the ventilation of hypoperfused lung zones and is clinically relevant as it is a strong predictor of mortality in patients with the acute respiratory distress syndrome ARDS and is correlated with higher airway driving pressures which are thought to be injurious to the lung lung stress
This trial aims to study the difference in dead space ventilation between conventional mechanical ventilation in volume-controlled mode and flow controlled-ventilation
