What causes intercostal and subcostal recession?

Intercostal retractions are due to reduced air pressure inside your chest. This can happen if the upper airway (trachea) or small airways of the lungs (bronchioles) become partially blocked. As a result, the intercostal muscles are sucked inward, between the ribs, when you breathe. This is a sign of a blocked airway.
