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

∙ 12y agoA conventional non-rebreather mask normally has three valves, an inhalation valve at the top of the reservoir and one on each of the exhalation ports. Many organizations require a removal of a side valve to prevent suffocation in the vent of source gas failure.
A partial rebreather mask has several definitions, so they can vary. I was taught that the inhalation valve was removed to allow the first portion of the exhaled breath to be captured back into the reservoir, ready for the next inhalation. This small amount of gas came from the anatomic deadspace and therefore did not undergo gas exchange (i.e. the oxygen is still there and CO2 has not contaminated it). This allows you to conserve gas.
The more common definition, however, is applied when the exhalation valves are removed, allowing room air to be entrained. This lowers the delivered gas and doesn't really speak to the "rebreathing" component unless one thinks that the patient can breath air that was exhaled through the ports. If this were the case, then blood CO2 levels would increase during use, which does not happen.

What is best way to administer oxygen to a child in moderate respiratory distress?
Non rebreather mask
What is the minimum oxygen flow when using a non rebreather face mask?
10 - 15 liters per minute
When using the non-rebreather mask on a victim who requires it at what levels are recommended for the flow rate?
10-15 liters/min
What Type of oxygen mask used with a reservoir bag?
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.
How long should a non-rebreather mask be used on 8-10 leters?
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.
Proper o2 flow for a non-rebreather mask?
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.
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.
How many CPR barriers are there?
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.
How do you perform CPR on quad patient?
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.

a partial airway is caused by a non tramatic mechanisim
Has anyone used oxygen concentrators for migraine headaches?
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.
Should you use a non rebreather mask on a copd in distress?
Many COPD patients have no history of smoking. What you are asking is whether high levels of oxygen are indicated for those with chronic lung pathologies. Regardless of WHY the patient is in distress, withholding oxygen to someone with demonstrated critically low oxygen levels does more harm than good. There are many confusing and contradictory statements made about oxygen delivery and many are based on bad assumptions. To simplify the story: 1) one should have a means of determining low blood oxygen levels; 2) aim for a blood oxygen level of 90-94% or so; 3) just because you are delivering 100% oxygen in the mask doesn't mean that the patient is receiving 100% to the bloodstream (i.e. a 24% mask can deliver "too much" oxygen and a 100% mask may not deliver enough depending on their condition); 4) the conventional non-rebreather mask only delivers 55-60% oxygen at the best of times, proven by research; 5) most textbooks are not research and often quote oxygen levels using no references that support those claims (thereby perpetuating the myth); 6) the worst possible thing one can do is with-hold oxygen to someone demonstrating critically low blood oxygen levels...deliver what you can to get them to 90-94%. A non-rebreather mask may not deliver enough oxygen to a patient as their condition worsens. Therefore, as long as you can demonstrate a "need" for oxygen, a non-rebreather mask may be perfectly acceptable and occasionally insufficient.
