If a pneumothorax is significant in size, it can alter the functioning of the lung and result in shortness of breath, chest pain, and a lower oxygen level. Anxiety, hyperventilation (rapid breathing), and a lower oxygen level in the bloodstream can cause lightheadedness as well as instability. A severe pneumothorax under tension can cause decreased cardiac output and a lower blood pressure; this too could cause lightheadedness or instability. If left untreated, it usually results in loss of consciousness and/or death. Once a pneumothorax is successfully treated the symptoms usually resolve right away. It is important to remember that a pneumothorax can recur if the puncture site in the lung is at all fragile. A repeat chest x ray can confirm the recurrence of pneumothorax.
