1
Q

Define crackles

A

low-pitched, non-musical sounds

2
Q

Define wheezes

A

high-pitched, musical sounds

3
Q

What should you consider if you note expanded lung fields

A

COPD or better termed RAO

4
Q

What should you consider if you note diminished lung borders

A

Pulmonary consolidation

pleural effusion

diaphragmatic hernia

5
Q

what are 2 common abnormal lung sounds

A

crackles & wheezes

6
Q

What should you consider with absent or radiating cardiac sounds

A

pleural effusion

lung consolidation

7
Q

what is dullness on percussion usually associated with

A

fluid accumulation within the thorax or increased tissue density

8
Q

what would you note with fluid accumulation within the thorax when percussing

A

a well demarcated horizontal line (straight line, “fluid line”) across thorax where there is a change in tone ventrally (dull) compared to dorsally

9
Q

what if you note localized areas of dimnishe sounds (dull, “thud”)

A

either trapped fluid or increased tissue density

10
Q

what is the rebreathing procedure used for

A

used to elicit and/or accentuate abnormal lung sounds by increasisn rate & depth of respiration.

can guide response to tx

11
Q

what does a CBC tell us

A

evidence of infection (neutrophilic leukocytosis)

fibrinogen: inflammatory vs non-inflammatory, chronic vs acute & severity of dz

12
Q

What other blood evaluation is important in resp cases

A

ABG: arterial O2 & CO2 tensions

13
Q

What specialized diagnostic tool is used routinely in equine resp disorder eval

A

Endoscopy

most relevan in dx of upper airway disorderd

14
Q

What common diagnostic tool is used to evaluate both upper & lower airways

A

radiography

15
Q

How is u/s helpful with resp cases

A

looking at thoracic wall

pleural space

normal lung & space

* remember can’t see through interposed gas or bone!

16
Q

What are 2 ways to sample pulmonary stuff

A

TTW

BAL

17
Q

what types of things can a TTW tell us

when is it indicated

A

cell types

can culture since sterile tech to perform

local or focal/multifocal dz

18
Q

when is a BAL indicated

A

diffuse dz

can’t culture as not sterile!

19
Q

what is the approach to eval resp cases

A
  1. categorize disease location
    1. upper vs lower airway
  2. categorize disease process
    1. infectious vs. non-infectious
20
Q

what will upper airway dz present with generally

A

unilateral or bilateral discharge

21
Q

which is the correct progressive order of respiratory structures from rostral to distal

A
  1. nares
  2. nasal passage
  3. ethmoid
  4. nasoharynx
  5. guttural pouch
  6. larynx
  7. trachea
22
Q

What helps categorize upper airway dz

A

unilateral or bilateral discharge

mostly or purely inspiratory component to difficulty or noise

absence of abn lung sounds on auscult

23
Q

what helps categorize lower airway dz

A

bilateral nasal discharge

symmetric airflow from nostrils

mostly or purely expiratory component to difficulty and/or associated abn sounds

abn lung sounds

24
Q

how to categorize infectious dz

A

serous (viral), mucoid/mucopurulent/purulent discharge

fever

mature neutrophilic leukocytosis w/ hyperfibrinogenemia on CBC however varies accordin to underlying cause, severity, chronicity & duration

25
Q

how to categorize non-infectious dz

A

serous, maybe mucoid discharge if any

normothermic

CBC generally normal, generally normofibrinogenemic

26
Q

examples of non infectious upper airway dz

A

allergic rhinitis

DDSP

LLH

27
Q

examples of infectious upper airway dz

A

infectious sinusitis

strangles

Viral respiratory dz (VRD)

28
Q

examples of infectious lower airway dz

A

pleuropneumonia

foal pneumonia

29
Q

examples of non-infectious lower airway dz

A

recurrent airway obstruction (RAO)

smoke inhalation
