研究目的:

主要目的 评估新型“膈肌-呼吸肌异步指数”(DRAI,计算为30分钟自主呼吸试验(SBT)结束时测得的TFic与DTF的比值,即DRAI = TFic/DTF)在预测SBT失败方面的诊断准确性。 次要目的 (1)评估SBT期间DTF相对变化(ΔDTF%)和TFic相对变化(ΔTFic%)对撤机失败的预测价值。 (2)确定DRAI、ΔDTF%和ΔTFic%的最佳诊断截断值。 (3)比较DRAI、ΔDTF%和ΔTFic%与传统浅快呼吸指数(RSBI)的预测性能。 (4)通过多变量逻辑回归分析,探究DRAI是否为SBT失败的独立预测因子。  

Objectives of Study:

Primary Objective To evaluate the diagnostic accuracy of a novel "Diaphragm-Respiratory muscle Asynchrony Index" (DRAI), calculated as the ratio of TFic to DTF (DRAI = TFic/DTF) measured at the end of a 30-minute SBT, for predicting SBT failure. Secondary Objectives (1)To assess the predictive value of the relative change in DTF (ΔDTF%) and TFic (ΔTFic%) during SBT for weaning failure. (2)To determine the optimal diagnostic cut-off values for DRAI, ΔDTF%, and ΔTFic%. (3)To compare the predictive performance of DRAI, ΔDTF%, and ΔTFic% with the traditional RSBI. (4)To investigate whether DRAI is an independent predictor of SBT failure using multivariate logistic regression analysis.
