High-flow nasal cannula (HFNC) enables delivering humidified gas at high-flow rates controlling the oxygen inspired fraction (FiO2). Its efficacy has been demonstrated in hypoxemic acute respiratory failure. However, little is known about its use in hypercapnic acute respiratory failure (ARF). Therefore, we aimed to evaluate the effect of using HFNC through "Precision Flow" equipment as first line of ventilatory support for COPD patients with hypercapnic acute respiratory failure.
