Critical Care Nurses
Overview
Critical Care Nurses take care of the sickest patients in hospital units such as the ICU (intensive care unit) and coronary care unit. They closely track vital signs, lab results, pain levels, and breathing patterns using tools like cardiac monitors, mechanical ventilators, and IV pumps, and they react quickly if a patient starts to show signs of problems like sepsis or shock. They also lead care planning with doctors and other health professionals, help train newer nurses, and support patients’ families by explaining complex treatments and tough medical decisions.
