Chapter 171 Avian Respiratory System Disorders
Disorders of the respiratory system are very common in birds. The unique anatomy and physiology of the avian respiratory system can make the diagnosis and treatment of disorders of the respiratory system difficult for the veterinary clinician. This chapter will focus mainly on anatomy, physiology, and clinical management of disorders of the respiratory system of pet parrots. For ease of use, the respiratory system will be discussed based on anatomy, with separation of the upper respiratory tract and lower respiratory tract. Clinical signs of many different disorders are very similar depending on the anatomic location of the disease process.
Signs of upper respiratory tract disorders can be divided into nasal, sinus, or choanal disorders and tracheal or syringeal disorders. In many instances, diseases that affect one of these anatomic sites also affect another.
