Modulation of Minute Ventilation Ve with Intermittent Application of Mechanical Breaths in Addition to Nonassisted Spontaneous Breathing

In these modes, mechanical ventilator support is constant and independent of the patient's inspiratory efforts. Increased ventilatory demand does not result in any change in the level of mechanical support. However, by regulating the mechanical ventilatory rate, variable support of spontaneous breathing is possible. In the event of apnea, at least set Ve will be applied. However, since the patient can only breathe spontaneously between the mechanical breaths, the opportunity for free spontaneous breathing decreases as the rate of mechanical ventilation increases. This principle is applied during intermittent mandatory ventilation (IMV) [2].
