Historical information
The use of a catheter for oxygen therapy was introduced by Arbuthnot Lane in 1907. However, its true value can be seen in its use during WWI. Masks were cumbersome and uncomfortable for the wounded and nasal delivery of oxygen was received more easily. The Tudor Edwards' Spectacle-frame was manufactured in London during the 1930s. Dr Penn recorded that it was an inefficient means of oxygen therapy because of the smallness of the nasal tubes.
