Neonatal continuous positive airway pressure support system with nasal or nasal congestion CPAP (Nasal-CPAP) will continue to positive air flow into the airway CPAP ventilator. Refers to the spontaneous breathing conditions, the patient should have a stable respiratory drive force and the appropriate tidal volume, in the entire breathing cycle of artificial imposition of a certain degree of positive airway pressure, which is conducive to prevent airway collapse, increase the functional residual capacity, improve lung compliance, and improve oxygenation. In this mode, the ventilator only maintains a certain positive airway pressure, without mechanical ventilation. For spontaneous breathing of the newborn, to provide continuous positive pressure ventilation support.
