Background. There is a growing controversy about the use of oronasal masks (ONM) or total facemask (TFM) in noninvasive positive pressure ventilation (NPPV), so we designed a trial to compare the uses of these two masks in terms of effectiveness and comfort.Methods. Between February and November 2014, a total of 48 patients with respiratory failure were studied. Patients were randomized to receive NPPV via ONM or TFM. Data were recorded at 60 minutes and six and 24 hours after intervention. Patient comfort was assessed using a questionnaire. Data were analyzed usingt-test and chi-square test. Repeated measures ANOVA and Mann–WhitneyUtest were used to compare clinical and laboratory data.Results. There were no differences in venous blood gas (VBG) values between the two groups (P>0.05). However, at six hours, TFM was much more effective in reducing the partial pressure of carbon dioxide (PCO2) (P=0.04). Patient comfort and acceptance were statistically similar in both groups (P>0.05). Total time of NPPV was also similar in the two groups (P>0.05).Conclusions. TFM was superior to ONM in acute phase of respiratory failure but not once the patients were out of acute phase.

Noninvasive positive pressure ventilation, also called noninvasive ventilation (NIV), is delivered through a noninvasive device, such as a full-face mask. Unlike the systems for invasive ventilation, which is delivered through an endotracheal or tracheostomy tube, the NIV delivery system is not a closed system, and so it leaks. The size of the leak affects the tidal volume delivered and the ability of the patient to trigger the machine into inspiration or cycle the machine into expiration. The acceptable leak for most systems is less than 35% of the peak inspiratory flow (leakage may be expressed as a percentage or as liters per minute).
