Emergency and critical care refers to the medical services provided to patients facing life-threatening conditions or severe injuries. This type of care is typically delivered in emergency rooms or specialized units, such as intensive care units (ICUs), where healthcare professionals are trained to respond quickly to urgent health issues. In these settings, a team of doctors, nurses, and other specialists work together to stabilize patients, perform necessary procedures, and monitor vital signs. The goal is to provide immediate treatment to prevent further deterioration and improve the chances of recovery for critically ill or injured individuals.
