The most common underlying abnormality in secondary spontaneous pneumothorax is chronic obstructive pulmonary disease (COPD), and cystic fibrosis carries one of the highest associations, with more than 20% reporting spontaneous pneumothorax. If a patient is hemodynamically unstable with a high clinical suspicion of pneumothorax, needle decompression, or tube thoracostomy must be done immediately. [37][38], Ventilator-related tension pneumothorax has been found to have dire outcomes and result in death more frequently. Flume PA, Strange C, Ye X, Ebeling M, Hulsey T, Clark LL. Symptoms of iatrogenic pneumothorax are similar to those of a spontaneous pneumothorax and depend on the age of the patient, the presence of underlying lung disease, and the extent of the pneumothorax. Recurrences are more common in smokers, COPD, and patients with acquired immunodeficiency syndrome (AIDS). Tension pneumothorax has been reported during surgery with both single- and double-lumen tubes. Pneumomediastinum from barotrauma may result in tension pneumothorax and obstructive shock. 8.

[QxMD MEDLINE Link]. In a small pneumothorax, many patients may present without symptoms. Clinical presentation. Tension pneumothorax can result in rapid development of severe symptoms associated with tracheal deviation away from the pneumothorax, tachycardia, and hypotension. Young and otherwise healthy patients can tolerate the main physiologic consequences of a decrease in vital capacity and partial pressure of oxygen fairly well, with minimal changes in vital signs and symptoms, but those with underlying lung disease may have respiratory distress.
