The objective of this study was to verify the feasibility of using an Oxygenation Device with Reservoir and Positive End-Expiratory Pressure (ODRPEEP; DORPEEP in Spanish) and to analyze its safety with respect to mask leaks and carbon dioxide retention measured upon expiration. A quasi-experimental pilot study was designed with eight volunteers in two experiments to determine the degree of leaks from the device, according to the observation of water vapor particle diffusion, on the one hand, and of thermal images on the other. The results from this study showed that the mask from the DORPEEP© device at is tightest fit provided an adequate seal, although not fully airtight. In the thermal images and in the experiment with water vapor in our study, dispersions were mainly observed in the lower area in individuals with a beard. The DORPEEP© device was shown to have only slight leaks.
