Critical care medicine involves the assessment and management of a diverse array of clinical issues that represent the most severe manifestations of human illness. Patients in critical condition necessitate comprehensive care delivered by a well-coordinated team. The critical care physician, often known as an “intensivist,” may serve as the primary caregiver or act in a consultative capacity. It is essential for the intensivist to possess expertise not only in a wide spectrum of conditions prevalent among critically ill patients but also in the technological interventions and equipment utilized in intensive care environments. Additionally, the management of critically ill patients presents numerous complex ethical and social dilemmas, requiring the intensivist to be proficient in matters such as end-of-life choices, advance care planning, prognosis assessment, and providing support to patients and their families.
