People are slowly beginning to realize that masks and respirators will have to be worn everywhere and for a long time. Many began to hysteria. Tears, snot, everything ...
As an excuse, some have hinted that respirators that you can't breathe through will cause emphysema. Well, maybe not right away, but after a few years. We will all walk with oxygen cylinders on wheels. Have you presented?
In general, emphysema is included in chronic obstructive pulmonary disease along with advanced asthma and chronic bronchitis. That is, they do not recover from emphysema.
The meaning of emphysema is that the deepest part of the lungs, which looks like a bunch of small bubbles like soap suds, will swell, and through it, oxygen and carbon dioxide will be poorly exchanged.
In those deep, protected places inside our lungs, the air gets very close to the blood vessels, and gases easily penetrate into the blood and back.
It is clear that you and I need a lot of oxygen, so the area of contact between blood and air should be large.
For this, Nature has greatly crushed our lungs in the place where the air touches the vessels. Everything there resembles a thick foam from many small air sacs. Well, like the foam that is squeezed out of a dishwashing sponge. There are so many bubbles that their common surface allows us to suck several liters of oxygen from the surrounding air every minute.
Emphysema
And now emphysema. This is such a disease when the bridges between small air bubbles dissolve, and small bubbles turn into large ones. Merge. Their area of contact with blood vessels decreases, and less oxygen is absorbed. Shortness of breath turns out.
What to do to get emphysema
Many people think that if they inflate balloons or breathe through respirators for years, their lungs will swell. No. Well, that is, if you really pump your lungs with a pump, then they may burst, but it will be one hole.
In order for small air bubbles to burst and merge into one large bag, you need to dissolve the wall with them in many places at once. To do this, you need to poison the lungs with smoke for years, or maintain inflammation there, due to which various enzymes will slowly dissolve many small walls.
The process of emphysema formation takes place at the far end of our breath. That is, not on the nose, where we wear a respirator, but deep, deep inside the lungs. Where air meets blood. This is where you need to aim with some kind of chemistry to melt the bulkheads and bulkheads.
That is, inflating balloons, we will not get emphysema. But we can get it if we get closer to the blood vessels deep in the lungs. And you can get there through the blood.
Through the vein
Got the intrigue? Emphysema begins where the airways stick into the blood vessels. But from the side of the blood vessels, emphysema can also be triggered.
That is, either the debris enters the lungs through the respiratory tract, or the debris enters the lungs through the blood. Both that, and another leads to the destruction of these most tender places.
Who do you think has managed to throw garbage into the lungs through a vein for years? Right! These are the people who abuse something homemade and dirty through their veins. There, they really have insoluble dirt travels through their blood vessels, which clogs and corrodes small vessels that must come into contact with air from the respiratory tract.
Our lungs act like a large living filter. Anything that floats through the veins will sooner or later get stuck in the lungs. This is exactly what happens to the famous pulmonary embolism. There, blood clots from the veins in the legs clog the vessels in the lungs.
It turns out that the caustic muck in the veins will float to the lungs and can make holes there. The walls between the tiny air bubbles will dissolve to create large bubbles of emphysema. Shortness of breath will appear again.
Briefly speaking
Emphysema forms deep in the lungs at the junction of air and blood. To get yourself emphysema, you have to either breathe garbage or run garbage through a vein.
Well, masks and respirators will only reduce the concentration of debris in the inhaled air. So masks and respirators are more likely to be useful. Available?
