Question

What is the difference between a partial rebreather mask and a non-rebreather mask?

Answer 1

Hint: An oxygen mask uses the method of transferring the breathing oxygen gas from a tank to the lungs of the patient. Oxygen masks might cover only the nose or the mouth or even the entire face. They are usually made up of plastic, silicone, or rubber. In certain conditions, oxygen may be delivered through a nasal cannula rather than a mask.

Complete answer:
The basic difference between a partial rebreather mask and a non-rebreather mask is:

Partial rebreather mask	Non-rebreather mask
A partial rebreather mask has a two-way valve present between the reservoir bag and mask.	A non-rebreather mask has a face mask that is connected to a reservoir bag that is filled with a high concentration of oxygen.
A Partial rebreather mask has been designed in such a way that it holds the first 150ml of the breath which has been exhaled in the reservoir bag so that it can be used for the process of inhalation in the next subsequent breath.	A Non-rebreather mask contains a reservoir bag that is filled up with oxygen and as the oxygen concentration decreases due to the breathing, it subsequently gets filled up from the oxygen tank.
In this type of mask, carbon dioxide is exhaled into the reservoir bag.	In this type of mask, carbon dioxide is not even available at the time of inhalation.
In a partial rebreather mask, the side valves are closed during exhalation.	In a non-rebreather mask, the side valves are open during exhalation.

Note: Just like a non-rebreather mask, the partial rebreather masks also deliver oxygen therapy for the patient who needs the high-concentration oxygen but doesn’t need any help in the process of breathing. A partial rebreather mask is a mask that covers the nose as well as the mouth.
