I can size up most of the people who come through and get them where they need to go. But the quiet ones scare me, the patient who looks fine and then crashes an hour later. Today one walked in talking normally and I almost sent them to wait, until something made me look again. The ones who hide how sick they are still slip right past me.
More people experience this than they realize.
You can triage most patients but the quietly serious ones still slip past you.
If this sounds familiar, the Library can help you find the bigger picture.
