Abstract
Weaning from mechanical ventilation remains a major challenge for critical care physicians. Because subjective criteria are inaccurate, objective measurements consisting of clinical criteria and physiologic tests (weaning predictors) have been used to facilitate decision-making. An integrated weaning index calculated as the product of static compliance and arterial oxygen saturation divided by the frequency-tidal volume ratio appears to be more accurate than other currently available predictors. Despite the accuracy of this new test, a beneficial effect on outcome is yet to be proven.
摘要
脱机机械通气仍然是重症监护医师面临的主要挑战。由于主观标准不准确，因此使用包含临床标准和生理测试（脱机预测指标）的客观测量来帮助决策。作为静态顺应性和动脉血氧饱和度除以频率-潮气量比的乘积计算的综合脱机指数似乎比其他当前可用的预测指标更准确。尽管这项新测试具有准确性，但它对预后的有益影响尚未得到证实。
