Non-rebreather Mask:
It is a face mask with 2 one-way valves. This face mask covers both nose and mouth. A one-way valve is present between the reservoir bag and the face mask. Oxygen can only flow from the reservoir bag to the mask. The valve prevents entry of exhaled air into the bag. Another one-way valve lets the exhaled air to flow out to the atmosphere but prevents atmospheric air entering into it. Hence. there is no re-breathing.
Partial Rebreather Mask:
It is a face mask with 1 two-way valve. It is similar to non-rebreather Mask. The difference is in the valve that connects the reservoir bag and the face mask. Here, the valve is a two-way valve. This allows the first 1/3rd of breathe to get into the reservoir bag. Remaining exhaled air flows out to the atmosphere through the exhalation port.

A Rebreather or non-rebreather masks are used for delivery of oxygen in medicinal therapy.
A Partial re-breather mask has been designed to get hold of the first 150ml of the breath that has been exhaled into the reservoir bag so that it can be used for inhalation in the next subsequent breath. This part of the breath will be delivered initially at the finish of the inhalation stage. Therefore, it will be delivered to the body's anatomy called as the "dead space", where gaseous exchange will not occur. Therefore, during the breathing component, there will be no decrease in oxygen nor there will be any gain of carbon dioxide.
A Non-rebreather mask has a reservoir bag that is filled with oxygen and as the oxygen depletes due to the breathing, it gets filled up from the oxygen tank. With a NRB, a patient can breathe without anyone's help. The NRB helps in delivering high oxygen concentrations. Although an ideal NRB does not allow the external air to enter into the mask, still there are few cases when one of the 2 valves is opened to allow external air to circulate in order to avoid suffocation.
