Air bubbles in the lungs, often resulting in a condition called pneumomediastinum, are caused by air leaking from the lungs or airways into the mediastinum.
Common Causes of Air Leaks
The following factors can cause air to leak from the lungs or airways, leading to air bubbles:
- Injury: Trauma to the chest can damage the lungs and airways, causing air to escape.
- Disease: Certain diseases can weaken lung tissue, making it prone to rupture and air leakage.
- Increased Pressure: Elevated pressure within the lungs or airways can force air out. This increased pressure can stem from:
- Excessive coughing: Strong and prolonged coughing fits can raise pressure in the respiratory system.
Pneumomediastinum Explained
Pneumomediastinum is the medical term for the presence of air in the mediastinum, which is the space in the chest between the lungs. This condition often arises from air leaking from the lungs or airways, as described above.
Summary
In short, air bubbles in the lungs typically result from injuries, disease, or situations that increase pressure in the airways, causing air to leak into surrounding areas like the mediastinum.
