What are Chest wall disorders?

Chest wall disorders are a group of thoracic deformities that result in inefficient coupling between the respiratory muscles and the thoracic cage. The disorders are usually characterized by a restrictive defect and share the potential to cause long term hypercapnic respiratory failure.1

The most common chest wall abnormality leading to respiratory failure is thoracoplasty. Scoliosis and/or kyphoscoliosis may also cause severe respiratory failure.
Symptoms of respiratory failure include:

  • dyspnea on exertion1
  •  peripheral edema1
  • orthopnea1
  • morning headaches1
  • fatigue1
  • poor sleep quality1
  • loss of appetite.
