Positive thoughts and prayers sent, Art!
This cuts close to my heart. My oldest daughter aspirated meconium (baby poop) on birth that chemically burned her lungs, and she had to to go on an ECMO machine (Extra Corporeal Membranous Oxygenation) - basically an external lung - for 3 three days it give her lungs a rest to heal. It's fairly standard these days, and the whole machine is the size of a microwave oven. But back in 1991, it was a huge frightening rack of hoses, pressure regulators, heaters, filters, etc.
It's scary as Hell looking at your newborn child hooked up to all manner of machines, with huge cannulas going into their neck, taking blood out, oxygenating it, and putting it back in them after the lungs. She has a small scar on her neck that I call her Badge Of Courage.
I know this is a scary time for all, but the little guy will pull through, Art! Medical science can do all kinds of amazing things, and newborns are amazingly tough little things.
