Spontaneous pneumothorax can present from mild symptoms to life-threatening distress. When a pneumothorax is large or under tension, oxygen delivery to tissues is severely compromised. The most telling signs are rapid heart rate, mental status changes from reduced cerebral oxygenation, cyanosis, and reduced or absent breath sounds on the side of the injured lung. Those findings together point to significant lung collapse and impaired ventilation on the affected side, which is why this set of clues is the best fit for a severe pneumothorax scenario.

The other descriptions are less specific for a sizable pneumothorax. General shortness of breath with sudden chest pain and diaphoresis can occur with many conditions; fever with productive cough suggests infection; anxiousness with chest pain relieved by position fits other chest wall or pleuritic processes rather than a collapsing lung with decreased breath sounds and altered mental status.
