Comment on “Noninvasive Ventilation Weaning in Acute Hypercapnic Respiratory Failure due to COPD Exacerbation: A Real-Life Observational Study”

We have read with great interest the article by P. Faverio et al. published in this journal [1]. We thank the authors for being able to establish an adequate strategy of weaning from noninvasive ventilation (NIV) incorporating interruption of ventilation. The article also rightly highlights the lack of consensus and studies in this regard. Although the study has a retrospective design, the hypothesis tested and evidence provided are compelling. Yet, we consider that some interesting practical aspects are worth mentioning.
