Respiratory failure

Respiratory failure is a term to denote when the respiratory system fails in one or both of its gas exchange functions: oxygenation and carbon dioxide elimination. This results in arterial oxygen and/or carbon dioxide levels being unable to be maintained within their normal range. While it is not directly a radiological topic, it is useful to understand its general concepts.

Pathology

It can arise from a fault in any of the components of the respiratory system, and can, therefore, involve a problem in airways (trachea-bronchi), alveoli, central nervous system (CNS), peripheral nervous system (PNS), respiratory muscles, and chest wall.

Classification

It is broadly divided into two main subtypes:
