5 years ago my dad was vented before he died. I'm not blaming the vent in his case but this is what I learned from the experience. 1. Venting with intubation through the mouth can only be short term (less than 2 weeks) before it severely damages throat muscles etc. 2. Next step is to intubate through a cut in the throat for long term vent. 3. Once you start putting tubes and cuts in people in a hospital you introduce places for germs and bacteria to get into the body (sepsis is a big killer of hospital patients and my dad died with it/of it in addition to everything else). So my point is that a vent is/should only be a desperate measure protocol because once started it can go sideways quick.
