Age > 50 years and PaO₂ ≤ 90 mmHg are the two dominant predictive factors for secondary spontaneous pneumothorax in male patients: an observational study
Among male patients with SP, an age of 50 years offers higher sensitivity and specificity than an age of 40 years in distinguishing SSP from PSP. Furthermore, even after oxygen administration, PaO₂ levels in SSP patients remain lower than those in PSP patients. A PaO₂ threshold of 90 mmHg also demonstrates high sensitivity and specificity in differentiating SSP from PSP.
