Question

How many lpm is required for a non-rebreather mask?

Option 1:
a. 5-8 lpm

Option 2:
b. 10-15 lpm

Option 3:
c. 20-25 lpm

Option 4:
d. 30-40 lpm

Answer 1

The flow rate required for a non-rebreather mask is 10-15 liters per minute (lpm) to ensure that the patient receives a high concentration of oxygen without re-inhaling carbon dioxide.

Step-by-step explanation:

The correct flow rate for a non-rebreather mask is 10-15 liters per minute (lpm). A non-rebreather mask is a device used in medicine to assist in the delivery of oxygen therapy. This mask allows for the delivery of higher levels of oxygen and is designed to prevent carbon dioxide from being re-inhaled by the patient. By ensuring a flow rate of 10-15 lpm, the reservoir bag attached to the mask remains inflated, ensuring that the patient is breathing almost pure oxygen, typically around 60-80% O2 concentration. It is crucial to maintain the recommended flow rate to ensure adequate oxygen delivery and avoid the risk associated with re-breathing expelled carbon dioxide.
