This might make a smoker think twice-
There are two sizes of chest vents. 4.7mm is the little one. The big one is 9.3mm, about three times the size of the little vent tube.
Getting a 4.7mm sucks.
But, when the doctor sticks the larger chest drain into you chest cavity you will be completely conscious, with a local anesthetic, and they will shoot you up with fentanyl in an effort to keep you from freaking out the other hospital patients. You will still sceream like a little girl, at least I did, and I was kicking to toe board of the bed with all my might while praying the two nurses trying to hold me down would not let go so that the doctor would not slip, meanwhile hoping that I might pass out from the sheer pain an terror of the totality of the circumstances.
206 bones in the human body. I have broken no less than 12 of mine, though not all at once, and the vent tube insertion was more painful than any of those. I even been shot with a nail gun, several times, and a coworker even nailed my hand to a table once. This vent insertion was more painful than getting shot, or stabbed,maybe kind of like getting shot in slow motion. I would not wish the experience on my worst enemy.
