Background
- Occurs when diver breathing compressed air ascends too rapidly
- Symptoms occur minutes to hours after surfacing
- Can occur without rapid ascent in pts w/ obstructive lung disease
- Lung rupture can lead to pneumomediastinum, pneumothorax, or air embolism
- Pneumomediastinum and pneumothorax do not require recompression
