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

BACKGROUND: The non-rebreather mask (NRBM) is used for many applications and in many patient care scenarios in which hypoxemia and resultant hypoxia are a concern. The NRBM is a low-flow oxygen delivery system that is easily deployed and capable of delivering a relatively high fraction of inspired oxygen (FiO2).The potential for ineffective carbon dioxide (CO2) removal at low flow rates is a safety concern.
