For pediatric patient tidal volume is considered 8 ml/kg. PRVC (Pressure Regulated Volume Control) Pressure-regulated volume control (PRVC) is kind of dual-controlled ventilation in which the ventilator attempts to achieve the volume target using a pressure- control gas delivery format at the lowest possible airway pressure with Decelerating inspiratory flow.

If after the completion of the expiratory time, no mandatory breath has been triggered, a mandatory breath is automatically applied (backup frequency). The control for respiratory rate (RR) therefore defines the minimum ventilation frequency.

PRVC Mode Control Screen Despite the advantage of the pressure mode, a long time or a sudden change in status of the patient, or pure breathing changes for a long time, the PRVC mode resolves this instability by constant monitoring of delivered parameters.

    NOTE Please ensure that, for adult patient tidal volume is considered 10 ml/kg. For pediatric patient tidal volume is considered 8 ml/kg. PCVs (Pressure controlled Ventilation with Assist Control) Pressure-controlled ventilation (PCV) is a pressure-targeted, time-cycled mode of ventilation. During inspiration, the ventilator adjusts the flow rate to keep the airway pressure at the set level.
