Chest circumference does increase when the lungs are inflated. The best way to measure circumference in its true number is to measure it without holding in air. The measurement is useful for properly fitting clothing and the like.
what is the relationship between chest circumference and lung function test
the presence of air or gas in the cavity between the lungs and the chest wall, causing collapse of the lung
chest lung and heart
Measuring chest circumference in adults is important for assessing lung function, heart health, and overall body composition. It can help detect abnormalities such as respiratory issues, heart conditions, or excessive weight gain that may impact one's health status. Tracking changes in chest circumference over time can also provide insights into the effectiveness of fitness routines or weight management efforts.
Lung cysts cause cough and chest pain
A cardiologist is a heart specialist and a pulmonologist is a chest/lung doctor.
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.
Chest cavity
Air in the chest (Thorax) causes the lung to collapse. This can be spontaneous or after chest injuries
chest/lung area
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.
This stops air from entering the chest cavity, and prevents collapsing the lung.
