          Abstract

          Background

          Despite the encouraging results of noninvasive ventilation (NIV) in chronic hypercapnic COPD patients, it is also evident that some patients do not tolerate NIV or do not benefit from it. We conducted a study in which COPD patients with stable, chronic hypercapnia were treated with NIV and nasal high-flow (NHF) to compare effectiveness.

          Methods

          In a multi-centered, randomized, controlled, cross-over design, patients received 6 weeks of NHF ventilation followed by 6 weeks of NIV ventilation or vice-versa (TIBICO) between 2011 and 2016. COPD patients with stable daytime hypercapnia (pCO 2≥50 mmHg) were recruited from 13 German centers. The primary endpoint was pCO 2 changes from baseline blood gas, lung function, quality of life (QoL), the 6 min walking test, and duration of device use were secondary endpoints.

          Results

          A total of 102 patients (mean±SD) age 65.3±9.3 years, 61% females, body mass index 23.1±4.8 kg/m 2, 90% GOLD D, pCO 2 56.5±5.4 mmHg were randomized. PCO 2 levels decreased by 4.7% (n=94; full analysis set; 95% CI 1.8–7.5, P=0.002) using NHF and 7.1% (95% CI 4.1–10.1, P<0.001) from baseline using NIV (indistinguishable to intention-to-treat analysis). The difference of pCO 2 changes between the two devices was −1.4 mmHg (95% CI −3.1–0.4, P=0.12). Both devices had positive impact on blood gases and respiratory scores (St. George’s Respiratory Questionnaire, Severe Respiratory Insufficiency Questionnaire).

          Conclusions

          NHF may constitute an alternative to NIV in COPD patients with stable chronic hypercapnia, eg, those not tolerating or rejecting NIV with respect to pCO 2 reduction and improvement in QoL.

          Nasal high-flow versus Venturi mask oxygen therapy after extubation. Effects on oxygenation, comfort, and clinical outcome.

          Oxygen is commonly administered after extubation. Although several devices are available, data about their clinical efficacy are scarce.

            Effect of Postextubation High-Flow Nasal Cannula vs Conventional Oxygen Therapy on Reintubation in Low-Risk Patients: A Randomized Clinical Trial.

            Studies of mechanically ventilated critically ill patients that combine populations that are at high and low risk for reintubation suggest that conditioned high-flow nasal cannula oxygen therapy after extubation improves oxygenation compared with conventional oxygen therapy. However, conclusive data about reintubation are lacking.

              Effect of Postextubation High-Flow Nasal Cannula vs Noninvasive Ventilation on Reintubation and Postextubation Respiratory Failure in High-Risk Patients: A Randomized Clinical Trial.

              High-flow conditioned oxygen therapy delivered through nasal cannulae and noninvasive mechanical ventilation (NIV) may reduce the need for reintubation. Among the advantages of high-flow oxygen therapy are comfort, availability, lower costs, and additional physiopathological mechanisms.
