Transcript of Respiratory Patterns - A Video Handbook

Canine -
Acute Progressive Respiratory Distress

Inspiratory Dyspnea
Stridor
Slow inhalation
Cyanosis

Congestive Heart Failure
Neoplasm
Pyothorax/Infectious
Chylothorax
Hemothorax
Pericardial disease




Pleural Effusion

Feline -
Acute Onset Dyspnea

Measurement of PCO2 and PO2

Arterial Blood Gas

Hypoxemia
:
Decreased arterial partial pressure of oxygen (PaO2) or hemoglobin saturation (SaO2)

Commonly approximated by Pulse Oximetry (SpO2)


Hypoxia
:
Decreased cellular oxygen and nutrient delivery (DO2)

DO2 = CaO2 X CO
CaO2 ~ Hb, SaO2, PaO2


Hypoxemia VS Hypoxia

Canine -
Acute Onset Orthopnea

6-8th Intercostal Space

Compliant patient

Needle
Catheter (over-the-needle)

Ultrasound Guided


From King’s Respiratory Disease in Dogs and Cats

Thoracocentesis

Inspiratory Dyspnea
Tachypnea
Shallow breathing
Excessive abdominal component on inspiration

Masks
O2 cages
O2 tent
Nasal catheters
Intratracheal catheter
Endotracheal Intubation/Tracheostomy

50-100ml/kg/min = 40% FiO2

Oxygen Supplementation

Measurement of oxygen saturation (SaO2)

Pulse Oximetry

Hypoxia

Circulatory:
hypoperfusion/shock

Anemic:
anemia
dysfunctional Hb

Histotoxic
cyanide

Hypoxemic

Hypoxemia vs Hypoxia

Hypoxemia

Hypoventilation

Ventilation-Perfusion Mismatch (V/Q)

Pulmonary Shunt

Diffusion impairment

Decrease Inspired Oxygen (FiO2)

Questions...
Difficult but important
Use other respiratory noises to help
Coughing, vocalization
Inspiratory
pulmonary disease
extrathoracic airways
Expiratory
intrathoracic airways
