Question

To ensure you deliver the highest concentration of oxygen with a nonrebreathing mask, you should __________.

1) Adjust the flow rate to 6-10 L/min
2) Ensure a tight seal around the mask
3) Use a reservoir bag
4) Administer oxygen at room temperature

Answer 1

To ensure the highest concentration of oxygen with a nonrebreathing mask, use a reservoir bag, ensure a tight seal, and adjust the flow rate.

Step-by-step explanation:

To ensure you deliver the highest concentration of oxygen with a nonrebreathing mask, you should:

1. Use a reservoir bag: A nonrebreathing mask should have a reservoir bag attached to it, which allows the collection of oxygen-rich air and prevents the rebreathing of exhaled air.
2. Ensure a tight seal around the mask: It is important to ensure a tight seal around the mask to prevent the entry of ambient air and ensure that the oxygen delivered is not diluted.
3. Adjust the flow rate to 6-10 L/min: The flow rate should be set between 6-10 L/min to provide a high concentration of oxygen.
