Evidence is increasing that long-term noninvasive ventilation (LTNIV) can improve outcomes in individuals with severe, hypercapnic COPD. Although the evidence remains unclear in some aspects, LTNIV seems to be able to improve patient-related and physiologic outcomes like dyspnea, FEV and partial pressure of carbon dioxide (Pco) and also to reduce rehospitalizations and mortality. Efficacy generally is associated with reduction in Pco. To achieve this, an adequate interface (mask) is essential, as are appropriate ventilation settings that target the specific respiratory physiologic features of COPD. This will ensure comfort, synchrony, and adherence that will result in physiologic improvements. This article briefly reviews the newest evidence and current guidelines on LTNIV in severe COPD. It describes an actual patient who benefitted from the therapy. Finally, it provides strategies for initiating and optimizing this LTNIV in COPD, discussing high-pressure noninvasive ventilation, optimization of triggering, and control of inspiratory time. As demand increases, clinicians will need to be familiar with this therapy to reap its benefits, because inadequately adjusted LTNIV will not be tolerated or effective.
越来越多的证据表明,长期无创通气(LTNIV)可以改善严重高碳酸血症 COPD 患者的预后。尽管在某些方面证据仍不明确,但 LTNIV 似乎能够改善患者相关和生理结果,如呼吸困难、FEV 和二氧化碳分压(Pco),并降低再住院率和死亡率。疗效通常与 Pco 的降低相关。为此,需要一个合适的接口(面罩),以及针对 COPD 特定呼吸生理特征的适当通气设置。这将确保舒适度、同步性和依从性,从而带来生理改善。本文简要回顾了严重 COPD 中 LTNIV 的最新证据和当前指南。它描述了一位受益于该治疗的实际患者。最后,它提供了在 COPD 中启动和优化 LTNIV 的策略,讨论了高压无创通气、触发优化和吸气时间控制。随着需求的增加,临床医生需要熟悉这种治疗方法以从中受益,因为调整不当的 LTNIV 将无法耐受或有效。
