Correct spelling for the English word "iron lung" is [ˈa͡ɪ͡ən lˈʌŋ], [ˈaɪən lˈʌŋ], [ˈaɪə_n l_ˈʌ_ŋ] (IPA phonetic alphabet).
An "iron lung" refers to a mechanical device or apparatus designed to assist individuals suffering from paralysis or significant respiratory conditions by providing mechanical respiration. It is essentially a large cylindrical chamber made of iron, enclosing the patient's body from the neck down, and is constructed to maintain negative pressure inside. This apparatus is specifically designed to facilitate the movement of air into and out of the lungs, assisting the patient's breathing process.
The iron lung functions through a process called negative pressure ventilation. When a person is placed inside the iron lung, the chamber is sealed tightly, except for the patient's head, typically resting outside the apparatus. By creating a vacuum or negative pressure, the iron lung enables the external air to flow into the chamber, causing the patient's chest to expand. Subsequently, this creates the necessary force to draw air into the lungs for inhalation. Conversely, the negative pressure also aids in expelling carbon dioxide-rich air during exhalation, contributing to the complete ventilation process. The airflow within an iron lung can be regulated, adjusting the pressure levels according to the patient's needs.
Historically, iron lungs were widely used during the polio epidemic in the early 20th century when the disease caused severe paralysis, including paralysis of the respiratory muscles. Over time, advances in medical technology, such as the development of positive pressure ventilators, have largely replaced the use of iron lungs. However, the term "iron lung" still represents an iconic symbol of a bygone era in medical innovation and the fight against polio.
The word "iron lung" is derived from the combination of two words: "iron" and "lung".
1. Iron: The word "iron" originates from the Old English word "iren" or "isærn", which are derived from the Proto-Germanic word "isarnan". This term eventually gave rise to the modern English word "iron", referring to a strong, hard, and durable metal.
2. Lung: The word "lung" comes from the Old English word "lungen", which is believed to have been derived from the Proto-Germanic word "lungō". This term is likely related to the Old Norse word "lunge" and the Old High German word "lunga", all referring to the organ responsible for breathing in humans and some other animals.
