Artificial ventilation is provided under circumstances in which a sufficient gas exchange cannot be secured by the patient’s own respiratory function. Artificial ventilation might be supportive or completely controlled by the respirator. Within the last few years a large variety of different respiratory modes have been established in critical care medicine, clinical anesthesia and pneumonology to offer optimal ventilatory support under any circumstances. The challenge of artificial ventilation increases dramatically when the lung itself is affected of the patient’s disease. In critical care medicine, the acute respiratory distress syndrome (ARDS) is one of the most important diseases which influence the outcome of these critically ill patients. ARDS represents a syndrome which is defined by an inhomogeneous distribution of ventilation and perfusion (V/P) followed by low oxygenation (oxygenation index, PaO2/FIO2 200) without cardiac dysfunction (wedge pressure 18 mmHg).
