High-acuity critical care at the bedside of the sickest patients in the hospital.
ICU (Intensive Care Unit) nurses care for critically ill patients who require constant monitoring, advanced life support, and rapid intervention. They manage ventilators, vasoactive drips, hemodynamic monitoring, and complex multi-system patients — typically with a 1:1 or 2:1 patient ratio.
What ICU nurses do
Manage ventilators, drips, and continuous monitoring for unstable patients
Titrate vasopressors, sedation, and paralytics based on hemodynamics
Respond to codes, rapid responses, and emergent procedures at bedside
Coordinate with intensivists, RTs, pharmacists, and consulting teams
Support families through some of the hardest moments of their lives
