What is critical care?
Critical care is given to a person with illness or injury that acutely impairs one or more vital organ systems such creating a high probability of imminent or life threatening deterioration in the patient's condition. Critical care services are defined as a physician's direct delivery of medical care for a critically ill or critically injured patient. It involves decision making of high complexity to assess, manipulate, and support vital organ system failure and/or to prevent further life threatening deterioration of the patient's condition. Examples of vital organ system failure include, but are not limited to: central nervous system failure, circulatory failure, shock, renal, hepatic, metabolic, and/or respiratory failure.
