Critical care nursing is one of the most demanding yet rewarding areas in healthcare. Nurses working in this field usually care for patients who are seriously ill or facing life-threatening conditions.

What is Critical Care Nursing?
Understanding what critical care nursing is starts with knowing about the basic definition. Furthermore, it is a specialised area of nursing that is focused on caring for patients with life-threatening illnesses or severe injuries who require constant observation and advanced medical support.
Also, it is different from general nursing. Instead, professionals in critical care units manage unstable patients whose conditions can change within minutes. They also usually work in ICUs, high-dependency units, and emergency departments.

Critical care practice goes hand in hand with intensive care nursing. It focuses on the treatment of patients in an ICU, where a complex array of monitoring systems and specialised equipment is used.
In intensive care units, nurses typically care for one or two patients in a given unit. This is because the patient-to-nurse ratio is low, thus requiring close observation and quick response to complications.
