The doctors were reluctant, but I made it my mission to prove that I didn't need it. I bought something to monitor my oxygen and put a cap on my trach. I then kept the trach cap unless I was sleeping and kept records of my oxygen level. The hard data convinced them. However, I was only able to do this because I had a visiting nurse who was also monitoring my oxygen level and I had family or friends who were with me most of the time.
