Critical care isn't hard because the problems are hard.
It's hard because the fixes fight each other.
The pressor that holds the pressure starves the gut.
The fluid that saves the kidney floods the lung.
The sedation that syncs the vent drops the pressure you just bought back.
You're not solving one problem.
You're solving all of them against each other, on a clock, with half the data.
That's the part I love.
