Why do ventilator settings still feel so intimidating?

You look at the display and feel behind, as if everyone else already understands it and you are the only one guessing. That feeling is not proof you are unfit for this work. It is proof you have not drilled it enough yet. No one is born knowing what a number on a screen controls in a person's breathing. They learned it one setting at a time, usually by asking a question that felt small or embarrassing. You are standing exactly where they stood. The real danger is not the machine. It is waiting to feel confident before you ask. Confidence does not arrive first and knowledge second. It is the other way around. Choose to learn the thing, and the fear loses its grip on its own.
