Modulation of Tidal Volume Vt through Mechanical Support of each Breathassisted Ventilation

Every inspiratory effort should be mechanically supported by the ventilator. Independent of different ventilatory modes, an increase in the patient's respiratory rate will result in more mechanical support. Stable spontaneous breathing and a sensitive synchronization mechanism are essential preconditions in these modes to ensure adequate alveolar ventilation and reduced work of breathing. This principle is applied during assist controlled ventilation (ACV) [5], pressure support ventilation (PSV) [6, 7], proportional assist ventilation (PAV) [8] and automatic tube compensation (ATC) [9].
