10 - 15 liters per minute
10-15 liters/min
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.
Non rebreather mask
As long as the patient needs it to improve oxygenation. The liter flow can be increased to 15L/min with a non-rebreather but if that's not sufficient the patient may need a cpap or bipap machine or even possible intubation.

You get the rebreather in Nellis Air Force Base and you can use it to breathe underwater. You can either gather supplies to make it or with a certain science level you can skip this step entirely.
There are numerous barriers; some more effective and safe than others. Short answer is 3 types; a mask, a non-rebreather mask, and a BVM. The older microshield and other types without a 1-way valve should no longer be used. At least, you want a CPR mask that has a 1-way valve. The next better would be the CPR mask with the O2 connection (and1-way valve). As you get more into the clinical setting, a non-rebreather and BVM would be the other types.
Do not change any of the CPR steps for a quad patient. Having supplemental oxygen, using a BVM, or non-rebreather mask would be helpful.
partial rebreather mask with attached with 1L reservoir bag that saves 1/3 of exhaled air, while rest gets out via ports covered with one-way valve. This allows patient to rebreathe some of the carbon dioxide, which acts as stimulator of breathing.
There are 4 liters in 4 liters.
