对f/V_T(呼吸频率与潮气量比率)和CROP(将肺气体交换的测定结果与有关呼吸系统的需求和呼吸肌储备能力的检测结果结合起来得出的指标)作为停机结果预测指标的价值进行了研究。将100名病人分成两组,第一组先测定成功停机与停机失败之间最能区别的指标阈值;第二组前瞻性评价新旧各项预测指标的正确性,各项指标的正确性还通过接收机工作特性
The value of f / V_T (respiratory rate versus tidal volume) and CROP (a measure of lung gas exchange measured in combination with respiratory demand and respiratory muscle reserve capacity) is used as a predictor of the outage outcome Were studied. 100 patients were divided into two groups, the first group to determine the most successful stop-down and stop failure between the most discriminating index threshold; the second group of prospective evaluation of the accuracy of the new and old forecast indicators, the correctness of the indicators also passed Receiver operating characteristics
