This document provides information about acute tracheobronchitis. It defines acute tracheobronchitis as a contagious viral infection that causes inflammation of the trachea and bronchial tubes, narrowing the airways. Risk factors include smoking, exposure to irritants, and genetic predisposition. Signs and symptoms include cough, mucus production, shortness of breath, and wheezing. Treatment involves rest, increased fluids, inhaled bronchodilators, cough suppressants, and antibiotics if a bacterial infection is present. Nursing care focuses on airway clearance, breathing exercises, maintaining a patent airway, monitoring for complications, and preventing spread of infection.
