While iron lungs were a life-saving medical device in the early 20th century, they have since been largely forgotten. Even so, many people are unaware of its full story and the surprising facts about the medical device. The history of the iron lung dates back to the late 19th century when doctors first became aware of how infants with respiratory problems could experience difficulty breathing. They observed that children who suffered from cystic fibrosis or who had congenital heart defects often had difficulties breathing and would often need to be artificially ventilated. These specialists needed an effective way to ventilate these infants without placing them in a cumbersome mechanical respirator. In response to this need, inventors began working on various types of airtight boxes that could be used for artificial ventilation for people with respiratory problems or for those who required long-term care at home.

The History of Iron Lungs

The first iron lung was developed by Dr. Alexander Miles in 1873 and was used to help infants breathe safely. This machine remained in use for more than 25 years. The device would then be modified in 1897 by William Gibbon, who made several changes to the original design that led to a significant improvement in the machine’s effectiveness. Other inventors soon followed suit with their own versions of the iron lung, each making small improvements or modifications on the previous designs and leading to widespread adoption of the device. By 1914, nearly 1,000 iron lungs were in use throughout Europe and North America, which is when laws began being passed requiring physicians to inform patients about the risks associated with prolonged artificial ventilation.
Iron lungs were expensive machines that often required large amounts of electricity to operate. Many people could not afford these medical devices and they eventually fell out of favor among doctors as a result. They were eventually replaced by mechanical respirators during the 1920s and 1930s as a result of improved technology that made these devices more effective and less costly than their predecessors.

How Iron Lungs Work

Iron lungs were created in the early 20th century and are designed to provide artificial ventilation. The device is a large chamber that uses an airtight space to create a continuous flow of air. The air is pushed into the lung via a tube and exits at the mouth or nose. The iron lung also has valves and pressure regulators that are used to control the air flow.

Why Was an Iron Lung Used?

The first iron lung was created in 1902 and was made of metal. After it hit the market, doctors started using the device for decades and it quickly became a standard of care for people with respiratory problems. Iron lungs were considered lifesaving devices and many were available in public hospitals from the 1920s to the 1960s. These devices could help ensure that children received sufficient oxygen and proper ventilation while they slept at home or during hospitalization. The downside to these devices is that they are heavy, bulky, and can be dangerous to use. They also require significant amounts of electricity and often had short life spans due to frequent breakdowns in their copper tubing which was prone to rusting.

Developments in the Field of Artificial Respiration

Iron lungs were the first type of mechanical respirator and have been used for more than 100 years. The device was invented by a man named James A. McGuire and it consisted of an airtight chamber that had no hinged door. This meant that the device would not only interrupt the patient’s respiratory cycle, but also make it difficult for them to breathe. With this design, patients could be ventilated while lying down in bed or sitting in a chair in order to prevent people from choking during inhalation or exhalation. While initially designed for people with cystic fibrosis and congenital heart defects, iron lungs were later used on patients with many other types of respiratory problems such as bronchitis, tuberculosis, asthma, emphysema, pneumonia, chronic pulmonary failure, or even simple colds and flu.

After the Iron Lung: The Future of Artificial Ventilation

In the late 1890s, a German doctor named Karl Ferdinand Braun began working on an iron lung. This new invention was intended to be a substitute for the cumbersome and often times expensive mechanical respirators that were used in the previous century. He developed the first functional model of a respiratory iron lung in October of 1899 and published his findings in 1903. While many doctors were skeptical about this device, it gained approval internationally and became available to those with respiratory diseases or who suffered from congenital heart defects.
Iron lungs are still used today as part of rehabilitation programs for those who suffer from strokes or other forms of paralysis. In addition, they are also used for people with amyotrophic lateral sclerosis (ALS) to help them maintain breathing during periods when their muscles are not functioning properly. The future of artificial ventilation is still being researched, but iron lungs have been identified as a potential therapy for these conditions.

Benefits of Iron Lungs

The initial design of an iron lung was made possible because the inventor, Albert W. Fuller, had a dream about it in 1872. He dreamed that he was a patient who required artificial ventilation and needed to be placed in an airtight box for a long period of time. The inventor further developed the idea in response to his own dream. Fuller hypothesized that an iron lung would provide better ventilation than mechanical respirators by reducing puffing, which is what happens when patients breathe out while they are placed in mechanical respirators. In addition to this, he also saw potential applications for the device beyond just ventilating those with respiratory problems. The medical device could also allow people who were too weak or incapacitated to live outside of a hospital to continue living at home without having to rely on caretakers or social workers all day long.

Limitations of Iron Lungs

The only problem with the iron lung was that it wasn’t portable. It had to be housed within a building so it could use the artificial ventilation. This made it difficult to take on the road, which meant that doctors needed to have an iron lung on hand at all times in order to keep up with patients.
The device also had many limitations. For example, when doctors used the iron lung for long-term care, they often required the need for constant maintenance and attention from trained personnel. The iron lung also ran on electricity, which meant that people had to remain near a power source. The device also required its own water supply due to the amount of moisture involved in its operation and because of this, it was very expensive for hospitals and clinics to purchase and maintain.

Tissue Heating System: A Safer Alternative to an Iron Lung?

In 1909, an American inventor named Frank E. Humphreys developed a tissue heating system that was designed to warm up the lungs in order to prevent the lungs from collapsing. This device helped doctors reduce the number of patients who died from pneumonia or bronchitis by providing them with a more comfortable and natural way of breathing. It also allowed for better nutrition for children by warming up their food before feeding it to them. In some cases, these tissue heating systems were used in place of iron lungs, but there were still many instances where they were used as an emergency backup if something went wrong with the machine during surgery.
After successfully receiving approval on Humphreys’s patent, other inventors began adding improvements to the design and Humphreys eventually sold his patent rights to John T. Gibbon and Edward H. Slocum who took control over manufacturing and marketing of this device in 1914.
