Question

When using a NRB with an oxygen reservoir, the EMS provider should adjust the liter flow to ________?

1) 2 LPM
2) 4 LPM
3) 6 LPM
4) 8 LPM

Answer 1

The correct flow rate for a Non-Rebreather Mask with an oxygen reservoir is typically 10-15 LPM to maintain the reservoir bag inflation and ensure high oxygen delivery.

Step-by-step explanation:

When using a Non-Rebreather Mask (NRB) with an oxygen reservoir, the Emergency Medical Services (EMS) provider should adjust the liter flow to typically 10 to 15 liters per minute (LPM). This high flow is necessary to keep the reservoir bag inflated and to ensure that the patient is breathing almost 100% oxygen. If the bag collapses during inhalation, increasing the flow rate may be necessary to maintain the proper oxygen delivery.
