The first day in the ICU is the most information-dense period of a critical illness. Lines are placed, samples are drawn, and a working diagnosis is being refined hour by hour.
Numbers on a monitor are trends, not verdicts. A single low blood pressure reading matters far less than the direction of travel over an hour. The clinicians at the bedside are watching the slope, not the snapshot.
Three questions are almost always useful for families: what are we treating, what would change the plan, and what does a good day look like from here. Clear questions get clear answers.
