Non rebreather mask
10-15 liters/min
You will need a physician's prescription to be able to purchase or rent an oxygen tank or concentrator. Depending on the level of need, you will also need either a supply of nasal cannulas, or masks (partial or non-rebreather), as well as bottles of sterile water with which you will use to moisturize the air. Oxygen tanks will need a regulator with a flow meter in order to adjust the volume of oxygen, as well as O-rings specific to the regulator and tank type.

Mercury is non-ductile and non-malleable, as it is a liquid.Lead is malleable but not ductile.
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.
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.
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.
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.
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.
High flow oxygen using a non-rebreather mask has been found to be extremely helpful in cluster headache, however in Migraine it is only infrequently found to be helpful.
