目的研究呼吸功（ＷＯＢ）对机械通气患者撤机的指导作用。方法选择机械通气并准备撤机的患者１５例，应用ＢＩＣＯＲＥ－ＣＰ１００呼吸监测仪床边监测病人ＷＯＢ及常规撤机指标，观察撤机成功与失败组的呼吸功值，并与常规撤机指标相比较。结果１３例撤机成功，７例ＷＯＢ正常（＜０．７５Ｊ／Ｌ），６例ＷＯＢ升高，撤机失败病人ＷＯＢ明显高于撤机成功的病人（Ｐ＜０．０５），撤机失败组常规撤机指标呼吸频率（ＲＲ）、最大吸气压力（ＭＩＰ）、每分通气量（ＶＥ）均显著高于撤机成功组，潮气量（ＶＴ）显著低于撤机成功组。结论ＷＯＢ对撤机有一定的指导作用，但并非敏感指标，对短期通气者常规指标较可靠。
Objective To study the effect of WOB on the weaning of patients with mechanical ventilation. Methods Fifteen patients were selected for mechanical ventilation and were ready for weaning. The bedside of patients with BICORE-CP100 respiration monitoring was used to monitor the patients’ WOB and routine weaning indexes. The values of respiration were observed and compared with those of conventional weaning indicators Compare Results The success rate of weaning was 13 cases, the normal WOB in 7 cases (<0.75J / L) and the WOB in 6 cases. The WOB in patients with weaning failure was significantly higher than that in patients with weaning success (P <0.05) Respiratory rate (RR), maximum inspiratory pressure (MIP), and minute ventilation (VE) were significantly higher in the group of conventional weaning indicators than in the successful weaning group, and the tidal volume (VT) was significantly lower than that of the weaning success group. Conclusion WOB has a certain guiding role on weaning, but it is not a sensitive index, which is more reliable for routine indicators of short-term ventilator.
