Non-Rebreather Oxygen Mask (Full Non-rebreather) AKA NRB, Medsource International (Case of 50 Adult Masks)

I was looking for a face mask to use with my O2 concentrater because when my nose got congested, the cannula could not deliver the O2. I had no idea what a "Non Rebreather" face mask meant. I got it and used it. It seemed to work. When I spoke with my medical supply company about the mask and asked if they carried one a bit shorter, I was advised the mask cannot be used with the concentrater because the user's exhaled air goes into the mask and combines its CO2 with the O2, after a short while the CO2 is dominant and can suffocate/poison the user. Only cannulas can be used with the O2 concentraters. I stopped using the mask. I did not investigate the matter further. The item says it is an oxygen mask, but cannot be used with a concentrater, according to the medical supply people, so how can it be used? If interested in this product, call your supply place, doctor or someone who knows about these things for advice.

The product listing very explicitly states that the item is a non-rebreather mask. It looks like the product photo has changed since I ordered the product and since the description may get updated as well, here's the original description straight from the product page, "Elongated oxygen mask molded of soft, transparent material. Tubing adaptor swivels for use on either side of patient. Soft vinyl reservoir bag. Complete with 7ft of oxygen supply tubing." What I received, pictured with this review, is what's commonly referred to as a "simple" Oxygen mask. It has no reservoir bag and no valves, making it useless for the intended use of non-rebreather masks - delivery of a high concentration of Oxygen. Reading the reviews, it appears I am not the only casualty of the bait and switch. The product photo when I ordered the mask was a stock photo of a non-rebreather mask. Now the product photo is a simple Oxygen mask. However, the product details still describe a non-rebreather mask. Given the mixed reviews and current ambiguities I suggest readers select a different vendor. I returned mine for a refund.

I did not receive the Non-Rebreather Oxygen Mask. I received a regular mask. There is no option for return so I will consult with Credit Card to stop payment. Update - Amazon gave credit for item.

These really are a waste of money! They are all deformed and no matter how much you try they dont form to the face! These are also absolutely NOT adult size!

The bag in which the mask came in was already opened. The exhaust valves are missing the actual diaphrams. this is useless for my purpose as well as non-sterile due to the bag being opened.

For the money, great, slight easy mods to make good. As expected.

I found that the one-way valves leak in the reverse direction, making it NOT a true non-rebreather and allowing room air in to reduce oxygen purity level. It is just OK for higher flow than a nasal cannula allows.

I got this for my Cluster Headaches and it didn't work like other masks... thought I was getting more sick and then figured out mask was not working 100%.
