You may be referring to a pneumothorax. This is a collection of air in the pleural cavity (between the lung and the chest wall). Symptoms include: pain and shortness of breath (dyspnea). In severe cases, if left untreated it can lead to cardiac arrest, but sometimes small spontaneous ruptures can heal themselves without treatment.
the presence of air or gas in the cavity between the lungs and the chest wall, causing collapse of the lung
Hemothorax is a collection of blood in the space between the chest wall and the lung (the pleural cavity).
Chest wall compliance refers to the ability of the chest wall to expand and contract during breathing, while lung compliance refers to the ability of the lungs to stretch and expand. Chest wall compliance can affect the pressure inside the chest cavity, while lung compliance affects the ease of lung expansion and air flow. Together, they determine how easily air can move in and out of the lungs, impacting overall respiratory function.
Air in the chest (Thorax) causes the lung to collapse. This can be spontaneous or after chest injuries
The pleura
If a broken rib punctures the chest wall on the left side, it can cause a condition called a pneumothorax, where air enters the space between the lung and chest wall, leading to lung collapse. This can result in chest pain, difficulty breathing, and in severe cases, it can be life-threatening and require immediate medical attention. Treatment may involve chest tube insertion to remove the air and reinflate the lung.

As we age, there is a decrease in the flexibility and elasticity of the chest wall due to changes in the structure of the bones, cartilage, and connective tissue. This increased rigidity can lead to decreased chest wall compliance, making it harder for the lungs to expand fully and decreasing overall lung function. Regular physical activity and breathing exercises can help maintain flexibility in the chest wall and support lung function as we age.
The fluid between the lung and chest wall helps the lungs expand and contract smoothly during breathing. It acts as a lubricant, reducing friction and allowing the lungs to move easily within the chest cavity. This fluid also helps maintain the pressure balance between the lungs and chest wall, which is important for efficient breathing.
I am not in the medical field. But if a lung collapses it means that there is air getting between the lung and the chest cavity creating pressure against the lung. A tube placed in the chest wall will relieve the pressure there. When the lung fills with air it pushes the air out of the tube. Then you can block the tube to give the chest cavity back the slight vacuum it had before. That is why your chest expands when you breate in. I hope this is right and I am not stepping on any toes out there.
Literally "air in the thorax", or air in the chest (where it shouldn't be) When air leaks anywhere in the space between your lung and chest wall (normally filled with slippery fluid) it increases the pressure around your lung, and pushes on your lung. This leads to your lung collapsing in on itself, because the pressure required for it to inflate is much smaller than the one keeping it deflated. Usually, you only get a fraction of your lung truly collapsed.
