Feedback:
When administering oxygen to a critically ill client using a nonrebreather mask, the nurse should remember that an oxygen concentration of more than 50 given for longer than 48 hours can cause oxygen toxicity in the client. Oxygen toxicity means lung damage that develops when oxygen concentrations of more than 50 are administered for longer than 48 to 72 hours. The best way to prevent oxygen toxicity is to administer the lowest FiO2 possible for the shortest amount of time.
