A non-rebreather mask (NRB, non-rebreather, non-rebreather facemask, etc.) is a device used in medicine to assist in the delivery of oxygen therapy. An NRB requires that the patient can breathe unassisted, but unlike low-flow nasal cannula, the NRB allows for the delivery of higher concentrations of oxygen.
