The most seriously ill or injured patients are cared for by the critical care intensivists, with locations in Arizona, Florida and Minnesota. These experts provide specialized care for people who have experienced major surgery or trauma, as well as those with other critical medical needs.

Mayo Clinic's critical care doctors treat people who need advanced monitoring and care. The full spectrum of critical care services is provided by doctors and other medical professionals specially trained in critical care (intensivists) who are present in Mayo Clinic hospitals 24 hours a day, 365 days a year.

Mayo Clinic’s Department of Critical Care and Multidisciplinary Program emphasizes a team-based approach to care. Critical care doctors lead a team of experienced professionals, which includes resident physicians, physician assistants, nurse practitioners, respiratory therapists, vascular access specialists, physical and occupational therapists, speech and language therapists, and nurses. Mayo Clinic critical care doctors also work closely with doctors from many specialties, including anesthesiology, internal medicine, pulmonary medicinecardiovascular medicine, cardiovascular surgery, neurosurgery, neurology, nephrology, pediatrics, surgery and transplant medicine. Together, the team provides high-quality and safe critical care in operating rooms, ICUs and other hospital settings.

Because the experience of being critically ill can have lasting effects, even after leaving the hospital, Mayo Clinic has developed an online support group for people who have been affected by critical illness or may be experiencing post-intensive care syndrome (PICS).

Mayo Clinic is nationally recognized for expertise in continuous care for critically ill, hospitalized patients.
