Which finding would be considered a late sign of a tension pneumothorax?

In tension pneumothorax, rising intrathoracic pressure progressively compromises circulation in addition to breathing. As the pressure builds, venous return to the heart becomes increasingly blocked, causing blood to back up in the large veins of the chest and neck. That backup manifests as distended neck veins, a sign that the patient is moving from respiratory distress toward hemodynamic collapse. It indicates the body is no longer able to compensate, so this finding is considered a late sign. Early signs are things like rapid breathing and a fast heart rate as the body tries to cope with hypoxia and reduced ventilation. Distended neck veins shows the next stage where venous congestion and decreased cardiac output are more clearly evident, signaling more advanced injury.
