The artificial lungs ventilation with the controlled volume and pressure support in preterm newborns with extremely low birth weight
In the investigation there was analyzed the efficiency of the trigger ALV with the controlled volume and support by pressure in preterm newborns with extremely low mass with the diagnosis of RDS and fetal pneumonia in the period of ventilator weaning in comparison with the regime of PSV. Indexes of mechanics of respiration, amount of complications, duration of the ALV and the child's staying in the intensive unit were evaluated in the group of 30 children of 25 till 30 weeks gestation. PSV - VG helps to maintain a stable breathing volume supply and the adequate alveolar ventilation at lower indexes of peak inspiratory pressure, inspiratory time which reduces an aggressive respiratory support and the events of air leakage. But it does not reduce the duration of ALV and amount of BPD.
