Which sign is considered a very late sign of tension pneumothorax?

In tension pneumothorax, signs worsen as intrathoracic pressure builds and compresses the heart and great vessels. Early on, you often see respiratory distress with dyspnea and reduced breath sounds on the affected side, sometimes with a hyperresonant chest. As pressure climbs, the mediastinum can shift away from the affected side, causing the trachea to deviate. This shift is a late, ominous finding because it reflects a body-wide struggle from severely elevated pressure and imminent circulatory collapse. While cyanosis can appear later as oxygenation worsens, it’s a nonspecific late sign and doesn’t by itself indicate the degree of tension in the chest. Therefore, tracheal deviation stands out as a very late sign signaling a critically advanced tension state requiring immediate intervention.
