c Example of Health Requirements Certificate of veterinary inspection, past medical history,

Respiratory Diseases Dr. Swain What is the function of the sinuses? Produce mucus that moistens the inside of the nose, 
also lightens the skull
What are the main parts of the larynx? Arytenoid cartilage, opening to trachea, vocal cord, 
What are the structures in the:
 guttural pouch –
cranial nerves, sympathetic trunk,  external and internal carotid arteries. Covers the 
temporohyoid joint. Located behind the cranial cavity, 
lies between the pharynx and beginning of 
 stilohyoid bone –  guttural pouch, cranial nerves trachea -   begins at the larynx and ends at the hilus  where it divides into the two bronchi carina –  ridge of cartilage in the trachea between the  division of the two main bronchi  bronchi –  enter the lung What is the specific characteristic of the 
epithelium? What is its function?
Made up of cilia, goblet cells and mucus, Lines the 
organs, vessels and body cavities
Exposed to fluid and air. Cells in the epithelium are closely packed together 
to help it form a protective barrier. Protects inner 
structures from dehydration and damage.
What is the mediastinum? What passes Lining separating pleural space from other thoracic 
organ structures. Blood vessels pass through.
Alveolar structure and surfactant Structure is called an alveolus. It contains alveolar 
type I and type II cells and inner surfactant layer. Also 
contains lamella body, tubular myelin, alveolar fluid 
and alveolar macrophage.
Lung injury and structures
background image Consolidation = collapse of lower airway
Can also have abscess formation which can lead to 
airway damage and inflammation.
Decreased gas exchange surface area
Contains the bronchi and alveolus, fibrin tissue
Nasal flow Should be equal. If reduced, there is some obstruction.
Also look for nostril flare
Types of nasal secretion Discharge either being serous or mucoid. Different 
color also. Blood would mean epistaxis.
Cough, respiratory effort Sign of exercise intolerance. Another name for 
respiratory rate and effort is tachypnea. Phase of 
respiration should be slow inspiration and expiration
Respiratory noise Stridor, stertor, snore, wheeze,  Fever Sign of respiratory infection Auscultation noises Normal = bronchovesicular sounds
Abnormal = crackles, wheezes, tracheal rattle
Rebreathing exam function Horse breathes into bag. Increased CO2 and 
encourages deeper breaths. Asses tolerance which is 
seen by coughing, rapid breathing and prolonged 
Testing for respiratory disease: viral testing and 
bacteriological disease
Cultures, PCR and virus isolation Ultra sound and x-ray Thoracic ultrasound – should clip to make it easier, 
evaluates the pleural surface and pleural fluid 
Transtracheal wash Culture and cytologic analysis Endoscopy Helps to visualize masses, determine if it’s a 
congenital or acquired defect and is able to asses 
during exercise
Broncoalveloar wash Cytologic analysis Upper airway:
background image Rattlesnake bike, signs and what you can/should do. Happens on the nose most often, can lead to edema and respiratory 
distress, can perform emergency tracheostomy to help
Ethmoid hematomas : clinical signs, what can be done Not a tumor but a low grade unilateral epistaxis. Can be treated by 
injecting formalin, a surgical resection. Reoccurrence is common
Nasal polyps: signs, occurrence Obstruct airflow. Result from chronic irritation Sinusitis: primary and secondary signs and treatment Unilateral discharge. Primary includes cushings syndrome. Secondary 
includes bad teeth and smell
Roaring horse with respiratory stertor: laryngeal hemiplegia: why 
does it happen?
Roaring = noise that happens during exercise and sounds like a snore. 
Happens to horses ages 3-7. Happens due to nerve injury – branch of 
vagus nerve. Tie back is the most common treatment. Risks include 
aspiration pneumonia and failure of technique.
Arytenoid chondritis: what is it? Exercise intolerance and respiratory noises. Common in race horses Epiglotis entrapment: what happens? Membrane covers the epiglottis called the aryepiglottic fold.  Strangles: clinical signs, transmission, passive carriers, bastard 
strangles, treatment
CONTAGIOUS! Signs include abscess formation. Transmission is from horse
to horse, direct contact with discharge. Horses considered contagious up 
to 6 weeks. Bastard strangles is a metastatic spread of abscesses. 
Treatments include vaccines and antibiotics
Guttural pouch mycosis: signs, consequences Signs include difficulty swallowing and nose bleeds. Consequences include
cranial nerve damage
EIPH: Clinical signs, cause, types of horses affected, treatment 
and management
Signs include exercise intolerance and on rare occasions, bloody noses. 
Happens in high performance horses. Treatments and managements 
include nasal dilator bands and furosemide.
Shipping fever: reasons, predisposing factors Transport stress. Predisposing factors include strangles ­ Influenza >> Horses unique: Pleuritis + Pneumonia = 
o Pleuropneumonia has three Stages:  o I  Exudative stage,
