Which finding is an early sign of tension pneumothorax?

When air rapidly accumulates in the pleural space, the affected chest area becomes hyperresonant on percussion because there’s more air than normal in that space. In tension pneumothorax, this air build-up happens early and is one of the first clues that the lung on that side is collapsing while pressure within the chest rises. That increased air causes the loud, hollow sound you hear when tapping the chest. JVD can appear as pressure mounts and venous return falters, but it isn’t guaranteed early and can vary between patients. Tracheal deviation indicates a more advanced shift of the mediastinum, which tends to occur later as pressure grows. Pale skin is nonspecific and not an early, reliable sign of tension pneumothorax. So hyperresonance to percussion stands out as the earliest telling sign.
