Background A new form of therapy that provides humidified high-flow oxygen through a nasal cannula has been introduced recently as an alternative in the treatment of spontaneously ventilating patients with high oxygen requirements. Objective The aim of the study was to evaluate the efficacy of a nasal optiflow device in the management of chronic obstructive pulmonary disease (COPD) patients with acute exacerbations in comparison with a conventional venturi mask. Patients and methods Forty-five COPD patients with respiratory failure type II admitted to the RICU at Abbasia Chest Hospital were recruited and divided into two groups: group 1 included 20 randomly selected COPD patients with acute exacerbations connected to a venturi mask; group 2 included 25 randomly selected COPD patients with acute exacerbations connected to nasal high flow (NHF) oxygen with an optiflow system. All patients were subjected to full history taking, thorough clinical examination, and routine laboratory investigations with chest X ray (CXR) and repeated analyses of arterial blood gases (ABGs). Results No statistically significant difference was observed between the two groups with respect to baseline ABG variables (on admission). In both methods (NHF and venturi mask) there was statistically significant improvement in ABG variables in the form of raised pH, PO 2 , and O 2 saturation and reduced PCO 2 when compared with baseline ABG values. Although there was no significant difference in weaning results between the two groups, there was significant decline in PCO 2 in the NHF group. There was no significant difference in the outcome and end result between the two groups; successful weaning was achieved in 70% of patients in the venturi group and in 64% of the NHF group, whereas failure was reported in 30% of patients in the venturi group and in 36% in the NHF group. Conclusion The nasal optiflow device is highly expensive compared with the venturi mask, although both are approximately equally successful in the treatment of COPD patients with respiratory failure type II.
