HFOV devices, used in the gravest situations, use small bursts of air at a high rate aiming to prevent further lung damage.
Innovative medical device ideas are cast aside because corporations have no interest in small markets. Fox Biomedical aims to change that with newly patented technology that will go head to head with the current single manufacturer!!! .
Thru lack of creativity or an effort to maintain lucrative profit margins or the fact that ownership has changed hands six times there have been NO advancements in in over twenty years. That's a shame !!!
