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.
Non rebreather mask
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.
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.
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.
10 - 15 liters per minute
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.
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.
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.
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
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.
