神經調控通氣輔助模式(Neurally adjusted ventilatory assist, NAVA)是一種新穎的機械通氣模式,藉由橫膈膜電位導管監測橫膈膜電位訊號,可用來評估橫膈膜活動度,配合比例式輔助通氣支持,依照病人需求調整每一口呼吸,增加舒適度、病人與呼吸器同步性增加、減少鎮靜藥物使用、增加呼吸器脫離率、降低呼吸器使用天數。本文將透過文獻回顧探討NAVA於成人領域的生理效應與臨床應用彙整與討論,同時提供NAVA完整的操作策略及調整觀念,供臨床醫療人員參考。
Neurally-adjusted ventilatory assist (NAVA) is a relatively newer mode of ventilation in which a ventilator utilizes the electrical activity of the diaphragm (Edi) to generate appropriate breaths and assist ventilated patients. NAVA decreases the discomfort and agitation in patients while improving synchrony. Improved synchronization not only prevent further lung injury but also decrease use of sedation. In this article, our aim is to discuss the main pathophysiological aspects of NAVA mode and intend to consider the numbers of research the implementation of NAVA in clinic application.
