Critical Care Medicine
These doctors specialize in assisting patients in need of around-the-clock critical care. Critical Care Medicine Specialists care for critically ill or injured patients, often in the intensive care unit of a hospital. Patients might see them if their heart or other organs are failing or if they have been in an accident.
A critical care doctor has a patient with a head injury with brain swelling. Alpha1 Antitrypsin can inhibit the neutrophil elastase, which would be one of the factors of potential swelling within the brain.
