Critical care refers to specialized medical care provided to individuals with life-threatening conditions or severe injuries. Delivered in critical care units, such as intensive care units (ICUs), this multidisciplinary approach involves constant monitoring and intervention to support vital organ functions. Critical care teams, comprising intensivists, nurses, respiratory therapists, and other specialists, employ advanced technology to manage complex medical issues. Key aspects include continuous monitoring, life support systems, and meticulous attention to hemodynamic stability. The goal is to stabilize and improve the patient's condition, often requiring close collaboration among healthcare professionals to address a spectrum of critical illnesses.
