Summary This prospective, single centre, randomised, cross‐over study compares patient tolerance of the facemask and mouthpiece for delivery of non‐invasive ventilation in an intensive care unit. Twenty‐seven patients with acute respiratory failure were scheduled for two 45‐min sessions of non‐invasive ventilation with facemask and mouthpiece. The order of the sessions was chosen at random. Nurses and patients assessed the tolerance of both techniques using a visual analogue scale. The time spent by nurses and the changes in respiratory parameters were recorded. The facemask was better tolerated than the mouthpiece; all the cases of non‐invasive ventilation withdrawal ( n = 5) occurred with mouthpieces (p = 0.026). Less nursing time was required using the facemask for the 22 patients who underwent both procedures (p = 0.01). However, the difference in tolerance scores was not significant. Non‐invasive ventilation with both facemask and mouthpiece improved the P a o 2 / F i o 2 ratio, increased the pH and decreased the P a co 2 . Only non‐invasive ventilation with the facemask lowered the respiratory rate. The facemask appears to be a better initial choice for non‐invasive ventilation when compared to mouthpiece, but both can be effective.
