A non-rebreather mask aka a trauma mask that delivers a maximum inspired FiO2 of 85%. It is essentially a normal Hudson mask with a reservoir bag attached to which oxygen is piped in at a rate of over 10L/min. The mask is essential as even at rest, peak inspiratory flow rate may reach 15L/min, which is the maximum rate at which most wall oxygen systems and certainly cylinders deliver at.
The point of a rebreather mask is to prevent rebreathing of expired gases via one way ports on the walls of the mask and to provide a reservoir of oxygen to prevent entrainment of air if inspiratory flow rates rise.

What is a reservoir bag used for on a standard non-rebreather oxygen mask?
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.
What is used with the oxygen mask?
Oxygen
What type of care would you provide for a person with an oxygen tubing and mask?
That's used to giving the person more oxygen. It doesn't need a particular type of care as such - but the environment should be kept fire safe in view of increased oxygen levels.
What are the three methods used to administer oxygen?
Oxygen can be administered by nasal cannula, mask, and tent.
What is bag valve mask?
A bag valve mask is a bag used to resuscitate a patient by supplying air or oxygen directly into the trachea and into the lungs.

What does the acronym NRB stand for?
The acronym NRB stands for "Non-rebreather mask". These are used in medical emergencies where the patient requires urgent oxygen therapy, as the mask allows higher concentrations of oxygen to enter the body.
Why did my friend die after putting on oxygen mask?
Your second question was: "can you overdose on oxygen wearing an oxygen mask?" The answer to that is no. Oxygen masks - as used by divers, fighter pilots and sometimes hospital patients - always offer a mix of oxygen and nitrogen so that oxygen poisoning cannot occur. However, if you were to put on a mask that makes you inhale only pure oxygen, it would after a little while start to poison your central nervous system. As to 'why your friend died': I have no idea.
What type of math and science was used to create the gas mask?
a lot of math
What is the primary purpose of a gas mask?
To enable you to breathe properly in a situation with lack of oxygen. They were used a lot durning the 2nd world war, but a minders form of mask is used today for things like spray painintng.
What is the difference of partial rebreather mask and non rebreather mask?
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
What the reservoir used for?
A reservoir is used to contain something, such as water or other liquid.
