Dear Editor,
Lung sliding has traditionally been assessed in a binary manner—present or absent—primarily to exclude pneumothorax in point-of-care lung ultrasound. However, emerging evidence suggests that this qualitative approach may overlook clinically meaningful information contained in the magnitude of pleural motion itself. Recent studies increasingly indicate that the amount of lung sliding, rather than its mere presence, reflects underlying lung mechanics and regional ventilation patterns.[...]
