Question from Edy
My doctor wants me to use a re-breathable mask for EWOT. I’m worried about that it is made from plastic. Is there any way that I can offgas this by heat? I don’t want to be breathing any fumes from it. I don’t know what type of plastic it is, but assume it isn’t something an MCSer would want to be breathing.
Thanks, Edy

First, for those of you who don’t know what EWOT is, it’s Exercise With Oxygen Therapy. What’s that? It’s the use of oxygen as a health supplement to enhance athletic performance or simply to bring the body’s oxygen needs up to normal. It seems there are a wide variety of health effects that are a result of oxygen deficiency (see EWOT – Exercise with Oxygen Therapy,
I wasn’t able to find out what type of plastic an oxygen mask is made of, however, oxygen can also be delivered via a “cannula” (search on “oxygen cannula” for online sources), which is just a little piece of hard plastic that fits in your nose. This would be much better than a soft plastic mask. I just visited a friend of mine in the hospital this week, and she had a cannula.
Hard plastics outgas much less than soft plastics as a general rule.
