Respiratory System [intro] Flashcards
T/F: Presence of CS @ rest is usually indicative of more severe dz process
True!
What is the pressure/volume of pulmonary system vs bronchial system
Pulmonary = low pressure, high volume
Bronchial = high pressure, low volume
What is the average RR for:
- Rest
- Trot
- Gallop
- 12/min
- 70/min
- 150/min
What is the total resistance of airflow from upper airway @ rest vs exercise?
Rest = 2/3 or 66%
Exercise = 80%
T/F: seeing abdominal press indicates that this is an upper airway dysfunction.
False!
Abdominal press = LOWER airway dysfunction
Extended head and neck+inspiration noise = UPPER airway dysfunction
What CS manifests pleural pain?
Abducted elbows
Name major differences between crackles and wheezes:
Crackles = low pitched, not musical
Wheezes = high pitches, musical
When percussing thorax, what indicates fluid accumulation?
What do you see on rads?
Dullness
Will see fluid line
What is the rebreathing procedure? Why is it important?
Must do it for a complete pulmonary auscultation.
It increases the rate/depth of respiration and used to accentuate abnormal lung sounds
What values tell you infection/inflammation is present?
CBC:
- infection = neutrophilic leukocytosis
- inflammation = fibrinogen
What does blood gas tell us?
O2 stats
use arterial blood
Why perform endoscopy?
Helps diagnose upper airway diseases
T/F:
Endoscopy = upper airway Rads = upper and lower airway
True!
T/F:
If want to see surface parenchymal dz = rads
If want to see general parenchymal dz = US
False
Surface = US
We do US and think we may have pleuropneumonia, what do we do next?
Drain and then rads!
*if try tracking rads 1st it will be all washed out and white b/c of the fluid
What are the major differences/indications of TTW vs BAL?
TTW [transtracheal wash]
- focal dz
- infectious dz
- sterile technique that can be cultured
BAL [bronchoalveolar lavage]
- diffuse dz
- non-infectious dz
- non-sterile technique
Do we perform biopsies/aspirates?
Rarely
Biopsies can have complications with horses
Upper Airway Dz vs Lower Airway Dz patterns:
Upper = inspiratory
Lower = expiratory [also can hear abnormal lung sounds]
Infectious vs non-infectious dz:
Infectious = fever, inflammatory leukogram, high fibrinogen
Non-infectious = serous discharge [all else normal range]
Examples of NON-INFECTIOUS, UPPER airway dz [3]
Allergic rhinitis
DDSP [dorsal displacement of soft palate]
LLH [left laryngeal hemiplasia]
Examples of INFECTIOUS UPPER airway dz: [3]
Infectious sinusitis
Strangles
Viral respiratory dz
Examples of NON-INFECTIOUS LOWER airway dz: [2]
Recurrent airway obstruction
Smoke inhalation
Examples of INFECTIOUS LOWER airway dz: [2]
Pleuropneumonia
Foal pneumonia
