What are intercostal retractions a sign of?

Intercostal retractions are a clinical sign indicating severe respiratory distress. This phenomenon occurs when the muscles between the ribs (the intercostal muscles) draw inward during inhalation, demonstrating that the body is making a greater effort to breathe. This typically happens when there is an obstruction in the airway or in conditions where the lungs are not functioning adequately, leading to inadequate oxygenation. The presence of retractions signals that the respiratory muscles are overworking, which is a concerning indication for the patient's respiratory status. Recognizing intercostal retractions is crucial for healthcare professionals, as it often necessitates immediate attention and intervention to address the underlying cause and improve the patient's breathing.
