John Haven Emerson was born February 5, 1906 in New York City. He was the son of Dr. Haven Emerson (A highly respected New York City Commissioner of health for many years). John Emerson was a self-taught American inventor of biomedical devices. Emerson specialized in respiratory equipment. (www.poliopalace.org,n.d.) In 1931, John Emerson introduced and improved upon a less expensive iron lung. The Emerson iron lung had a bed that could slide in and out of the cylinder as needed, and the tank had portal windows, which allowed attendants to reach in and adjust limbs, sheets, or hot packs. The patient lies within the chamber, which when sealed provides an effectively oscillating atmospheric pressure. The Emerson lung was lighter, quieter,
In 1909, Morgan opened a clothing manufacturing company and continued to invent new devices. Morgan was interested in workers’ safety. He invented a safety hood, called an “inhalator,” which he patented in 1912 (patent #1,113,675). This device was an early version of the gas mask. He won the grand prize for the invention in 1914 at the second International Exposition of Safety and Sanitation.
EIA was discovered as early as the first century AD when it was observed by Aretaeus the Cappadocian that "if from running, gymnastic exercises, or any other work, the breathing becomes difficult, it is called Asthma" (Randolph, 1997, p. 54). After that, no further research or emphasis was placed on EIA until 1698 when Sir John Floyer, an asthma sufferer, wrote the Treatise on Asthma in which he reported the first delineation of asthmogenic activities. In 1864 Salter recognized that EIA was exacerbated by cold air, and in 1962 Jones determined the pattern of bronchodilation followed by bronchoconstriction that is characteristic of EIA. Such strokes stimulated additional research, and in 1984 and...
In class we talked about how Emerson influenced Ralph Ellison and was in a way Ellison’s predecessor. In an article by Christopher Hanlon called Eloquence and Invisible Man. The author talks about how Emerson’s piece of writing influenced much of the rhythm of Ellison’s writing. The author, Christopher Hanlon, focuses on many different aspects of the first speech that the Invisible Man gives in alliance with the Brotherhood.
We know there many talented individuals that is blanked throughout the world past and present. Talent is marked in every race, but some people just don’t get enough credit and many individual are over look for the great work they have done. Most people may not have heard of Ernest Everett, but he was a great scientist in his time. Ernest Everett graduated from Dartmouth College in 1907 and continued to the University of Chicago earning his Ph.D. in zoology in 1916. It was very difficult for him being a colored man and attending college in those times, but his ambition and determination drove him to succeed. Earnest Everett was an extraordinary marine biologist who was very innovative when it came to many important discoveries, which include
Very little is known about John Webster's childhood. Much of the information about his family was destroyed when the parish to which his father's family belonged burned down in 1666, during the Great Fire of London (1). The records destroyed in that fire would have been invaluable in piecing together Webster's youth. What is known is that Webster was born in what is estimated to be 1590 or earlier (2), to the son of a carriage-maker. His father's business often supplied rental coaches for the nearby prison and courthouse, as well as corpse collectors during the years the Black Plague ravaged England (3). This likely contributed to Webster's preoccupation with death that becomes evident in several of his other plays.
To begin with, Medical Ventilator can deal with some tissue or systems’ problem, like the muscle tissue or respiratory system. The Respiratory system is a biological system consisting of specific organs and structures used for the process of respiration. It has two functions: breathing, and exchanges gases. The respiratory system aids in breathing, and air is inhaled through the nasal and oral cavities. It moves through the pharynx, larynx, trachea and bronchi into the lungs. Then air is exhaled, flowing back through the same pathway. What’s more, Inside the lungs, oxygen is exchanged for carbon dioxide waste through the process called external respiration. This respiratory process takes place through the alveoli. Oxygen from inhaled air diffuses from the alveoli into
For almost 40 years after the end of World War II, the work of Ernest Everett Just was an African-American biologist and educator best known for his pioneering work in the physiology of development, especially in fertilization of the fundamental role of the cell surface in the development of organisms. In his work within marine biology, cytology and parthenogenesis, he advocated the study of whole cells under normal conditions, rather than simply breaking them apart in a laboratory setting.
The relatively obscure release of Ralph Waldo Emerson’s first book, Nature, in 1836, gave few clues to the celebrity and influence which would later be enjoyed by its author. The piece was originally published anonymously but did mark the beginning of Emerson’s future role of mentor, lecturer, and teacher. His scope was wide, attracting a number of admirers across Massachusetts, reaching audiences from both his literary works, as well as his numerous appearances on the university lecture circuit.
Medical technology today has achieved remarkable feats in prolonging the lives of human beings. Respirators can support a patient's failin...

Have you ever wondered how the world would be like if there wasn’t innovative people before our time? What would health care be like without the help of scientist and doctors who have gone before us? Sir John Simon was born in London on October 10th 1816, he was the sixth child out of fourteen. He was the son of Louis Michael Simon and Mathide Nonnet. Simon’s father was a shipbroker which brought the family some wealth. His father had served in the Committee of Stock Exchange from 1837-1868. When Simon was in grade school is, family had enough money to send him to excellent schools. During his adolescents, he attended Pentonville for seven and a half years. In 1833, Simon became an apprentice to Joseph Hennery Green, he was a surgeon at St. Thomas Hospital and a professor of surgery. This began his journey in healthcare and science.

Galen was a Greek physician and scientist who studied the circulatory system and how blood flow worked; his research persuaded people that lungs were the main source of blood flow in the body. He was born in AD 129 and died in AD 217. Other physicians during Harvey’s time of research had thought that the lungs were the source of blood flow throughout the body. Standard citizens did not know what to think or who to believe when it came down to the circulatory system, but Harvey had done a lot of research and tests trying to prove that the lungs were not as important as other physicians and scientists said they were. Harvey published his findings in the book Anatomical Studies on the Motion of the Heart and Blood in Animals, in 1628. Harvey’s peers did not respect his work in this field. It was another fifty years after Harvey’s death that his work was fully appreciated and accepted. Since the time of Harvey and Galen, surgeons and scientists today can thoroughly track the flow of blood in the standard circulatory system (Lauer 1). Although Harvey did not win any awards for his outstanding research, there is an award named after him that describes what he did during his lifetime and how he proved that the blood flow in the circulatory system does not depend on the lungs.
A ventilator is a mechanical device that is designed to aid the body in moving gas in and out of the lungs. Breathing, the process of moving air into and out of the lungs, and can be also called as ventilation. The process of breathing includes, inhaling certain amount of volume through the mouth or nose and moving into the pharynx, trachea and bronchi respectively, During inspiration, The diaphragm contracts by moving downwards that helps to increase the chest cavity space which helps the lungs to expand. During expiration, the diaphragm relaxes decreasing the chest cavity space to aid the lungs in expiration. In the alveoli, it exchanges with the carbon dioxide rich blood with fresh oxygen. This process is carried out multiple time in a minute, with a frequency of 12 beats/min when at rest and increases accordingly with exercise or various emotional states.
The invention of machines occurred in the Egyptian city of Alexandria in the 3rd century BCE and had a profound effect on the practice of medicine “Berrey Alexandrian Physiology.” The invention of machines, such as valves, pumps, levers, and wedges influenced the way in which ancient physicians described and understood the body, in addition to providing new methods for treating conditions. Machines provided a means to treat previously untreatable conditions, served as a form of entertainment, and contributed to a separation of power between medical practitioners.
