Question

Iron lung is an artificial device to assist respiration to an unconscious patient. Who invented it?
A. Joseph lister
B. Philip Drinker
C. Spembly Llord
D. Ignaz Philipp Semmelweis

Answer 1

The iron lung or artificial respirator was first known to provide temporary and, in some cases, permanent breathing support for people suffering from paralysis of structure which helps in respiration that are diaphragm and intercostal muscle.

Complete answer:
The iron lung was developed in 1929 and it came out as a very important tool for taking care of lungs of patients suffering from paralytic polio.
To find the answer, we will understand all the above options.
First, Joseph lister: He was an English surgeon and also a founder of modern antiseptic surgery. He used carbolic acid as antiseptic and developed a technique to apply it with combined heat sterilization of instruments. It brought a decrease in mortality and this contribution helped in development of sutures and draining tubes in medical science.
So, he didn’t invent iron lungs.
Now the second options are: Philip Drinker. He was an American engineer and industrial hygienist who invented artificial lungs. Most patients would live in an iron lung for a period of weeks or months until the virus had run its course and the patient could breathe normally again on their own.
Option third says Spembly Llord, we are not aware about anyone who is named and famous for any discovery with this title.
Last option is: Ignaz Philip Semmelweis, he was a Hungarian physician who discovered the cause of puerperal fever and also introduced antisepsis into practice.

So, the correct answer is option B, Philip Drinker.

Note:
The polio epidemic occurred in the 1930s and 1940s. Polio infection causes paralysis of the breathing system in the human body. The polio vaccination helped in development of modern ventilators and widespread use of tracheal intubation and tracheostomy.
