The glide sign indicates normal to-and-fro motion of the lung sliding along the chest wall during respiration, suggesting the lung is in contact with the chest wall.
Answer for screen readers
The glide sign indicates normal to-and-fro motion of the lung sliding along the chest wall during respiration, suggesting the lung is in contact with the chest wall.
More Information
The glide sign is a key indicator in lung ultrasound to rule out pneumothorax, as its absence may suggest air in the pleural space.
Tips
Mistaking the absence of the glide sign as a normal finding can lead to a missed diagnosis of pneumothorax. Always correlate with clinical symptoms.
