Emphysema

its tar because of its sticky property

The correct spelling is "emphysema" (a chronic respiratory disease).

Yes, smoking is not the ONLY cause of this condition.

Have theystopped smoking yet?

A positive correlation, nothing more.

It depends on the drug. Some may inhibit breathing or other vital functions to fail, others might cause a slow painful process of your liver or kidneys shutting down.

Emphysema can have genetic components, but it is not typically directly inherited like a Mendelian genetic disorder. Certain genetic factors can increase the likelihood of developing emphysema, particularly in combination with environmental factors like smoking.

people with emphysema feel more tired than other people because they are having difficulties with their breathing, so there bodies are using more energy and muscles to help them breathe hence why they get tired quickly and more tired than others. hope this helps!! x :)

yes

People do not recover from emphysema, but sometimes they survive for many years, despite having the disease. Eventually emphysema is fatal.

People with this type of emphysema have a hereditary deficiency of a blood component, an enzyme inhibitor called alpha-1-antitrypsin

Emphysema is a shunt my friend. Shunts are diffusion limited by definition. There is a limitation to diffusion because the endothelial alveolar interface is destroyed in emphysema. Several factors go into diffusion. The permeability of the membrane/solubility of the gas, the thickness of this interface, the surface area available for exchange, and the difference in partial pressure of the gas of interest on both sides (in the blood vessel and the alveolus). In emph., SA is diminished (there is little fibrosis in emph., it's not a thickness issue). We say that surface area is diminished because of less healthy lung tissue participating in gas exchange for the reasons I just mentioned. Also think of pulmonary fibrosis, where thickness is increased. Such people cannot be treated with 100% O2 very successfully. You are not doing anything to ameliorate the initial problem: bad lungs. Blasting them with O2 will do little.

Dead space or perfusion limitation on the other hand does respond to 100% O2. In the case of a pulmonary embolism, there is perfusion limitation. This is tricky, because perfusion limitation shows equilibration of gases by the end of the capillary, so what good would adding more O2 do? Again, increasing the partial pressure difference across HEALTHY lung (in this instance) will cause a higher oxygen saturation than typical in the remaining capillary beds not blocked by the embolus. That is why 100% O2 will treat a pulmonary embolus or anything perfusion limited, assuming that you have less than 100% dead space.

I literally know nothing more on the subject.

Creighton SOM is crazy good

Emphysema itself does not typically cause black spots on the lungs. Black spots on lung imaging are often indicative of other conditions, such as infections, tumors, or exposure to certain substances like coal dust (coal worker's pneumoconiosis). However, emphysema can be associated with changes in lung tissue and structure, but these are usually not characterized as black spots. It's important to consult a healthcare provider for an accurate diagnosis and assessment of lung health.

Emphysema is a disease which does tend to get worse once it appears. However, it will get worse faster if a person continues to smoke.

A person with emphysema should avoid smoking and exposure to secondhand smoke, as well as pollutants and irritants in the air. They should limit physical activities that cause excessive shortness of breath and may benefit from a pulmonary rehabilitation program. Additionally, maintaining a healthy diet and staying hydrated are important to support overall lung function. Regular check-ups with a healthcare provider are essential to monitor the condition and adjust treatment as needed.
