神经调节辅助通气在急性呼吸窘迫综合征中的应用

Neurally adjusted ventilatory assist and acute respiratory distress syndrome

ARDS患者机械通气的目标是保证足够的氧合，最小的呼吸机相关肺损伤。机械通气中保持ARDS患者自主呼吸很重要，一种基于膈肌电信号的辅助机械通气-神经调节辅助通气，相比传统机械通气，在人机协调性、呼吸机相关肺损伤等方面更有优势。

Patients with acute respiratory distress syndrome （ARDS） require mechanical ventilation,which is aiming at ensuring adequate oxygenation and minimizing ventilator-induced lung injure. It is important for patients with ARDS to maintain spontaneous breathing during mechanical ventilation. Neurally adjusted ventilatory assist （NAVA）, a ventilation assist mode, is based on electrical activity of the diaphragm. Compared with traditional mechanical ventilation, NAVA would decrease patient-ventilator asynchrony and ventilator-induced lung injury.
