What is the iron lung?

Iron lungs, better known as a fan with negative pressure, are a medical device to help patients breathe when they have problems with it themselves. The iron lungs were largely replaced by positive pressure fans, as the iron lungs are extremely cumbersome and difficult to use, although individuals continue to use iron lungs and are probably used in some forms of non -invasive therapy to treat humans and respiratory conditions. Drilling disease that causes paralysis in some patients. Suddenly, the polio was a disaster throughout the world until vaccines developed in the 1950s. The vaccines were developed and iron lungs were a key tool for treatment for people paralyzed by palsy. In patients with temporary paralysis, a negative pressure fan would help them breathe, while Thej recovered and patients with permanent paralysis may be limited to the iron lungs for the rest of their lives.

iron lungs consist of a long chamber, classic steel, although other materials can also be used. The patient's body is located inside the chamber, while its head projects the valve out. When the chamber is sealed, the pressure inside can be regulated by pumps. When the pressure in the iron lung drops below a certain point, the lungs automatically inflate in response, air intake from the outside, and as the pressure rises, the lungs are released.

The

iron lung versions were developed in the 18th century, but the first functional and easy -to -iron iron lungs were developed in 1927 by Philip Pinker. The iron drinker quickly filled the hospital department around the world and inspired a number of improvements to be ease and process. While iron lungs are no longer produced, some museums with collections of antique medical equipment have one on the display, sometimes with accompanying material written by people who lived or spent time in iron lungs.

for the patient is lifeInside the iron lungs, highly limited, which ensures that the patient requires lifelong care. The development of fans of functional positive pressure caused a huge difference in the lives of many patients with palsy, allowing them to be much more mobile and functional, because these fans rely on the tube inserted into the lungs to inflate and release the lungs.
