Nurses played a foundational role in the development of critical care units by recognizing the need for specialized environments to manage the most vulnerable patients. During the latter half of the 20th century, nurses began grouping their most critically ill patients together to ensure the more effective and efficient use of modern medical technology.1

This innovation allowed nurses to provide focused, high-intensity care within a systemized environment. By centralizing these patients, nurses were able to better administer increasingly complex treatments and maintain the rigorous aseptic and infection-control protocols necessary for advanced medical interventions. Furthermore, as hospitals faced rising technological and clinical demands, nurses continued to humanize these technical procedures, ensuring that the care remained patient-centered despite the increasingly impersonal nature of high-technology medicine.1
