The efficacy of such software has been previously demonstrated with tidal volumes as low as 100 mL. Specific computer software has been developed to allow the ventilator to compensate for the volume loss within the circuit. Discrepancies between the set and actual delivered tidal volume can result from various factors including circuit compression volume and the impact of fresh gas flow.
1 Tidal volume (VT) is usually measured by a sensor placed at the expiratory valve or within the expiratory limb of the ventilator. Precise control of tidal volume is one of the keys in limiting ventilator-induced lung injury (VILI), ensuring adequate ventilation, and improving outcomes in mechanically ventilated neonates.
