Secondary spontaneous pneumothorax(SSP): Symptoms, Diagnosis & Treatments
Secondary spontaneous pneumothorax (SSP) is a pneumothorax that appears as a complication of previously existing lung disease. Although almost all types of pulmonary complications can be seen, chronic obstructive pulmonary disease is the most common cause of SSP and 50 to 70% of SSP is caused by COPD. The severity of COPD is associated with the risk of SSP. For example, over 30% SSP due to COPD patients have FEV1 less than 1 liter and FEV1 / FVC ratio less than 40%. This OSN patient was also a COPD patient and showed SSP due to complication. Symptoms of patients with secondary spontaneous pneumothorax are manifested by air volume, tension, and age and respiratory reserve in the pleural space. Most SSP patients complain of dyspnea and chest pain on the chest with pneumothorax. Symptoms are more severe than in patients with primary spontaneous pneumothorax, because patients with SSP usually have less pulmonary reserve due to underlying lung disease. Patients with SSP due to infectious ...
