Four functions must occur in a coordinated manner if the lung is to adequately oxygenated the blood and eliminate CO2
Four functions must occur in a coordinated manner if the lung is to adequately oxygenated the blood and eliminate CO2
Ventilation = sufficient volume of air must move in and out of the lung each minute Distribution = distributed to an adequate number of alveoli that are being perfused with blood Diffusion = must diffuse across the alveolar capillary membrane into the plasma Perfusion = must be perfused with a proper proportion of blood
Respiratory distress is caused by
Respiratory distress is caused by
- A low arterial partial pressure of oxygen PaO2 (correct)
- A high arterial partial pressure of oxygen PaO2
- Increased arterial partial pressure of carbon dioxide (PaCO2)-hypercapnia (correct)
- Decreased arterial partial pressure of carbon dioxide (PaCO2)-hypercapnia
Primary indication for oxygen therapy is hypoxia-deficiency of oxygen at the tissue level
Often caged animals at rest will not show signs of until oxygen content is severely reduced

True (A)
Cyanosis is a reliable indicator of hypoxia especially if the patient is anemic

Hypoxia only acts a respiratory stimulus if PaO2 falls below 20mmHg
