Good approach in pediatrics to avoid CT. Measuring pneumothoraxes. Line A = lung apex to cupola. Line B = interpleural distance. Supplemental oxygen (non-rebreather mask) initially for all. 2020 study supports conservative therapy vs chest tube.

Free air within the peritoneal cavity can be recognized on supine abdominal films by identification of the median subphrenic space. We have termed this the "cupola sign." In a review of 100 patients with pneumoperitoneum, this sign was seen in 6 patients.
