The intermittent mandatory ventilation mode allows the patient to breathe spontaneously between breaths.The patient will receive a preset tidal volume at a preset rate.Any additional breaths that he initiates will be at his spontaneous tidal volume,which will likely be lower than the ventilator breaths.In assist/control ventilation,spontaneous effort results in a preset tidal volume delivered by the ventilator.Spontaneous effort during controlled ventilation results in patient/ventilator dyssynchrony.Positive end-expiratory pressure (PEEP)is application of positive pressure to breaths delivered by the ventilator.PEEP is an adjunct to both intermittent mandatory and assist/control ventilation.
