Possibly one reason could be to help monitor respiration. This could provide a visual clue to inspiration. But, the reservoir bag is to collect oxygen and thus keep a free flowing "reservoir" of oxygen for the patient to draw from as they inhale all the avilable air within the mask itself. There are exhaust valves located on either side of the face mask to exhale the CO2 and keep from drawing in room-air. Or even rebreathing the CO2.
nonrebreather (plastic face mask with a reservoir bag)
A nonrebreather mask (NRB) should have an oxygen flow rate of at least 10 liters per minute in order to deliver the maximum oxygen concentration.

An oxygen mask used with a reservoir bag is called a partial rebreather mask. It is designed to deliver high concentrations of oxygen by allowing the patient to rebreathe some of the exhaled air along with oxygen from the reservoir bag.

nonrebreather more precise and delivers higher concentration Partial Rebreather Mask - Conserves oxygen - Can be administered in concentrations of 40-60% using flow rates of 6-10L - This is useful when oxygen concentrations must be raised - Cannot be used with a high degree of humidity - Not recommended for COPD patients - Should NEVER be used with a nebulizer Non-Rebreaqthing Mask - High concentrations of oxygen can be administered accurately - Oxygen flows into bag and mask during inhalation - Valves prevents expired air from flowing back into bag - Cannot be used with a high degree of humidity
The first oxygen mask was invented by a gentleman by the name of Lewis Haslett in 1847. The device protected the lungs and was actually more like a gas mask at that time.
