What Is A Critical Care Specialist?

A critical care medicine specialist is a doctor who specializes in providing intensive treatment and care to a critically ill patient. To become a critical care medicine specialist, after graduating from medical school, a doctor completes a residency program in internal medicine, followed by a fellowship in critical care medicine. Other specialists such as anesthesiologists, surgeons, pediatricians, or pulmonary disease specialists may also obtain subspecialty or dual specialty certification in critical care.

A critical care medicine specialist is trained to manage severe and life-threatening conditions that require complex treatment and constant monitoring of body functions. Patients requiring critical care and life support are usually treated in intensive care units (ICU), coronary care, post-surgical care, or other specialized care units. Life-threatening conditions most commonly requiring critical care include acute respiratory distress syndrome (ARDS), shock, septicemia or sepsis, multiple organ failure, trauma, acute renal failure, traumatic brain injury, stroke, poisoning, surgical complications, as well as complications and comorbidities of acute myocardial infarction (heart attack), stroke, or heart arrhythmias.

Critical care specialists frequently work within a team that includes other physician specialists, as well as critical care nurses, respiratory therapists, pharmacists, dieticians, and others. In addition to providing treatment, critical care specialists can also counsel the patients and their families about prognosis, palliative care, and end-of-life decisions.
