Southmedic OxyMaskTM compared with the Hudson RCI® Non-Rebreather MaskTM: Safety and performance comparison

Abstract

The non-rebreather mask is an oxygen delivery system with many applications and has been a valuable tool in specific patient care scenarios. Under certain low-flow conditions, however, a lack of washout of exhaled gases and rebreathing of carbon dioxide may occur -- a situation scarcely addressed in the literature. This bench study compared two commercially available products in an attempt to shed more light on this important issue.
