What is the FIO2 range for a non-rebreathing mask?

The FIO2, or fraction of inspired oxygen, is a critical parameter in respiratory care that represents the percentage of oxygen in the air mixture that a patient inhales. A non-rebreathing mask is designed to deliver a high concentration of oxygen, making it suitable for patients who need significant oxygen support, such as those in respiratory distress or with hypoxemia.

The correct FIO2 range for a non-rebreathing mask is typically between 0.60 and 0.80, reflecting its ability to provide a high oxygen concentration to patients. This mask works by utilizing a reservoir bag that holds oxygen, which is delivered to the patient while simultaneously preventing the re-inhalation of exhaled gases. Because of this design, the non-rebreathing mask can effectively supply a higher FIO2, ensuring that patients receive an adequate level of oxygen during critical moments of need.

This understanding emphasizes the importance of accurately choosing the right type of oxygen delivery device based on the patient's condition, particularly in emergency or critical care situations. The other ranges do not adequately reflect the capability of the non-rebreathing mask to deliver high concentrations of oxygen effectively.
