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. A NRB requires that the patient can breathe unassisted, but unlike a low-flow nasal cannula, the NRB allows for the delivery of higher concentrations of oxygen. An ideal non-rebreather mask does ...
non-rebreather mask A non-rebreather mask (NRB) is a device used to deliver supplemental oxygen to a spontaneously breathing person. An NRB allows the delivery of relatively high concentrations of oxygen while using a constant flow rate, with relatively low waste, by accumulating the oxygen flow during exhalation in a soft bag, to be inhaled at ...

During the COVID-19 pandemic, masks with unfiltered-exhalation valves ran counter to the requirements of some mandatory mask orders. [ 60 ] [ 61 ] Despite the aforementioned belief, a 2020 research by the NIOSH and CDC shows that an uncovered exhalation valve already provides source control on a level similar to, or even better than, surgical ...
