Experimental: Asymmetrical high-flow nasal cannula
Asymmetrical high-flow nasal cannula will be set at 40 and 60 L/min in a random order. Temperature will be set at 37 degree celsius and inspired oxygen fraction (FiO2) will be adjusted to maintain oxygen saturation by pulse oximetry (SpO2) \>/= 94% in acute hypoxemic patients and between 92-94% in acute hypercapnic COPD patients
Active comparator: Conventional high-flow nasal cannula
Conventional high-flow nasal cannula will be set at 40 and 60 L/min in a random order. Temperature will be set at 37 degree celsius and FiO2 will be adjusted to maintain SpO2 \>/= 94% in acute hypoxemic patients and between 92-94% in acute hypercapnic COPD patients
