Just to inject (pun intended) a bit of levity into the ol' life/death discussion: a number of years ago we were setting up hospice care for my dad in his home. He had been on low-level oxygen for quite some time and we located the concentrator centrally in his smallish home so he could move around semi-freely. When hospice came we set up a hospital bed in his living room. When the hospice worker wanted to move the concentrator closer to the living room, I objected due to the excessive noise. I said "let's just extend the hose."
Her: "you can't add extensions, it will restrict the flow of oxygen too much."
Me "I'll turn up the flow. If you want 5 liters of oxygen, I'll set it to 7, then adjust it based on his pulse-ox reading."
Her: "it doesn't work that way."
Me: "yes, it does."
Her: "no, it doesn't. I do this every day."
I'm boiling mad at this point, but containing myself because my wife and sister are there and it's a stressful situation anyway. So....
Me: "Well, damn. If only one of us had ever studied fluid dynamics we could probably figure this out. Oh, wait a minute, that was me! I studied fluid dynamics! Aced that bitch, too!"
(ok, passed it is more accurate, but I was pissed off)
My wife loves to tell this story. And when I start to pontificate on any subject my kids will say "bet you studied fluid dynamics too, didn't you."
