Abstract :

1. This study was a randomized, controlled trial compå NHF with the Venturi mask in critically ill patients requiring oxygen therapy after extubation, with the hypothesis that NHF could improve oxygenation. 2. Patients mechanically ventilated for more than 24 hours were screened for enrollment. Just after extubation, patients were randomized to receive oxygen through the venturi mask (control group) or the NHF (intervention group). Randomization was done. In both groups, FiO2SET was adjusted to obtain an SaO2 between 92% and 98% (88–95% in patients with compensated hypercapnia). The Venturi mask or the NHF was applied for 48 hours or up to ICU discharge. Arterial blood gases, SaO2, FiO2SET, respiratory rate, mean arterial pressure, heart rate, and patient discomfort was recorded at 1, 3, 6, 12, 24, 36, and 48 hours. 3.As compared with the venturi mask, use of the nasal high flow after extubation results in better oxygenation for the same set FiO2. 4. The use of the nasal high flow is associated with fewer episodes of interface displacement and of oxygen desaturation
