icanis

Introduction

  • Patients with respiratory disease can present with a variety of clinical complaints such as coughing (most common), sneezing Sneezing , other upper airway noises often referred to as reverse sneezing, nasal/ocular discharge Rhinitis , decreased exercise tolerance, abnormal respiratory noise (stridor and stertor), abnormal breathing pattern, breathlessness, increased panting, collapse Collapse , acute respiratory distress Acute Respiratory Distress Syndrome (ARDS) , dyspnea, cyanosis.
  • Coughing is the most common complaint and can be classified as acute or chronic:
  • Dyspnea is also a common complaint and can be further classified as inspiratory or expiratory:
  • Abnormal respiratory noises can help in identification of the abnormal anatomical area:
    • Inspiratory stertor usually indicates a nasal problem.
    • Inspiratory stridor is usually associated with problems in the larynx (eg laryngeal paralysis).
    • Reverse sneezing is usually associated with problems in the nasopharynx (eg foreign body).
  • Nasal discharge can be bilateral or unilateral, and the discharge can be serous, hemorrhagic, mucoid, purulent:
    • Unilateral nasal discharge can be associated with foreign body, neoplasia, nasal aspergillosis Nasal aspergillosis/penicillosis.
    • Bilateral nasal discharge is more likely associated with lymphocytic-plasmacytic rhinitis (LPR), aspergillosis, neoplasia Nasal cavity: neoplasia.
  • Cyanosis is characterized by a bluish color on the mucous membranes and is due to a low percentage of saturation of hemoglobin with oxygen (which is an increased amount of the reduced form of hemoglobin) or to the presence of metahemoglobin. In anemic patients, cyanosis may not appear obvious due to the decrease amount of hemoglobin in blood. Cyanosis can be central or peripheral and may be intermittent or persistent. A patient with cyanosis represents a true respiratory emergency.
  • Some respiratory diseases have been described more commonly in some breeds, such as:
