When properly using a nonrebreather face mask, the following statement is true The concentration of inhaled oxygen will be approximately 90%.
What is a nonrebreather face mask?
- A non-rebreather mask, also known as an NRB or non-rebreather, is a tool used in medicine to help provide oxygen treatment.
- A NRB needs the patient to be able to breathe on their own, but in contrast to a low-flow nasal cannula, the NRB enables the administration of greater oxygen concentrations.
- Since an ideal non-rebreather mask prevents air from the environment from being breathed, an occurrence of a source gas failure (i.e., the oxygen cylinder being totally emptied) is dangerous and might result in death.
- The patient's mouth and nose are both covered by the non-rebreather mask, which is fastened to their head with an elastic string.
