1
Q
T/F: Cough can be stimulated by upper or lower dz or strictly voluntary
A
TRUE
2
Q
What are the protective mechanisms of the respiratory system?
A
Mucocilliary escalator- continuous ciliary motion starting at the level of the bronchioles
Cough refelx- remove secretions from the tracheobronchial tree proximal to the level of the segmental bronchi
3
Q
What nerve is involved in the involuntary reflex of the cough?
A
Vagal nerve
4
Q
Bronchoconstriction and cough are two separate reflexes
A
TRUE
5
Q
T/F: Bronchoconstriction is a constant component of a cough
A
TRUE
6
Q
What factors are involved in cough stimulation
A
Bronchoconstriction
Excessive mucous production
Deposition of inhaled particles
Release of inflammatory mediator
Exposure of hot/cold air
Intramural or extramural pressure
Sloughing of airway epithelium
Enhanced epithelial permeabiity (pulmonary edema)
7
Q
What cell lining is involved in upper respiratory tract?
A
Pseudostratified ciliated columnar epithelium
8
Q
How long does it take for the airway epithelium to heal?
A
7 weeks
9
Q
What cells are present in the terminal and respiratory bronchioles that helps clear the lungs?
A
Clara cells
10
Q
What do clara cells secrete?
A
Source of surfactant
Metabolizes airborne toxins
11
Q
What does surfactant do?
A
aids in maintaining patency of airway
12
Q
What is a specific test that should be ran while performing a respiratory auscultation?
A
Rebreathing
13
Q
What lung sounds are associated with pneumonia?
A
Increased lung sounds, crackles and wheezes
14
Q
What lung sounds are associated with pleuropneumonia?
A
Ventral dull sound
15
Q
What lung sounds are associated with pleural effusion?
A
Cardiac sound larger area than normal because of increased sound conduction
16
Q
What is the clinical manifestation of peracute cough?
A
Fever, depression, anorexia, pleurodynia
17
Q
What is hypernea?
A
Increased thoracic pressure, hypoxemia, hypercapnia and respiratory acidosis
18
Q
What is a common clinical manifestation with a coughing horse in terms of appearance?
A
Weight loss in short period of time
19
Q
What is a major cause (viral) of respiratory disease in horses?
A
Equine influenza
20
Q
How far can equine influenza be aerosolized?
A
>35 ft.
21
Q
What are common predisposing factors of influenza?
A
Crowding, transport and stress
22
Q
What is the difference in EHV4 and EHV1?
A
EHV 4: respiratory and reproductive
EHV1: respiratory and neurologic
23
Q
What is the incubation period for EHV?
A
1-3 days
24
Q
What are CS for EHV?
A
Conjunctivitis, lymphadenopathy, edema and vasculitis
25
Q
What is associated with equine multinodular pulmonary fibrosis?
A
EHV-5
26
Q
How can equine multinodular pulmonary fibrosis present?
A
Exercise intolerance or acute respiratory distress
