For adequate ventilation to occur the interpleural pressure needs to be to expand the lung.
The V/Q ratio is

3. Ventilation
Respiratory Failure




Ventilation or Oxygenation failure?

-Inadequate ventilation


Low O2 & High CO2

,-Thoracic pressure change inadequate, mechanical abnormality (Kyphosis, COPD,
Pneumothorax)
-Defect in Respiratory control center (CNS dysfunction, Drug OD)
-Impaired muscular function (Neuromuscular diseases, spinal cord injury)


4. Oxygenation
Respiratory Failure




Ventilation or Oxygenation failure?
-Ventilation adequate
-Decreased lung perfusion (Right to left shunt, pulmonary embolism)
-Hemorrhagic shock
-Abnormal Hgb (Doesn't bind to O2, Carbon monoxide poisoning)
