6.04 Honors-Aqualung: Activity

A diver descending to a depth of 10 meters, is equivalent to the entire 150km of atmospheric air (1 ATA). This is due to water being much denser than air. If the diver were to descend another 10 meters, the water will exert a further pressure, equal to another atmosphere, 2 ATA.

“Instead of turning my oxygen off, Harris, in his hypoxically impaired state, had mistakenly cranked the valve open to full flow……” (8).

The water frame was invented in 1769 by Englishman Richard Arkwright and used flowing water as its source of power. We still use the water frame today but obviously it has been updated over and over again by multiple different people. The water frame is the name given to a spinning frame when water power is used to drive it.

It was Joseph Montgolfier of France, who in the late 18th century, first gave significant meaning to the modern use of the parachute by testing his device while jumping out of a hot air balloon. His success led to a plethora of balloonist stunt jumpers using parachutes.

Diana Nyad is an American author, journalist, motivational speaker, and long- distance swimmer. Diana is also the first person to swim from Cuba to Florida without getting injury, swimming one hundred and one miles in fifty- three hours. It was Diana fifth time standing on the Cuban shore, hoping that she will make it across that vast from Cuba to Florida. Not only has she tried four times but even the greatest swimmer in the world has been trying since 1950's and it hasn't been done yet. Knowing the risk of the dangerous wildness of an ocean, she still continues this great journey. Facing the sharks and box jellyfish, the deadliest venom are in these waters. From her previous attempt, she came close to dying. Diana team and her best friend

As a clinical facilitator, I provide learning opportunities to staff and nursing students at St Vincent’s Private Hospital Brisbane (SVPHB). Not long after I joined St Vincent’s, I encountered a patient who was receiving high flow oxygen (7 litres/min) via high flow nasal prongs without any humidification device running with it. The scene surprised me. Supplemental oxygen is

Matthew gitzinger invented the first and revolutionary reusable gas on 2042 ,december 1st at the age of 40 years old he changed the world of transportation but he was not alone on this invention he had help and not ordinary help in this invention he had some world renowned scientist by his side the dream of reusable gas has been one of many but his dream has grown big.

Jacques Cousteau played an important role in oceanography, he was a French naval officer, explorer, scientist he https://ed.ted.com/on/aFghd4xe and studied the sea and all forms of life in water. One thing he did was co-develop "Aqua Lung". In 1943 the first aqua lung prototypes came about. These prototypes made in Boulogne-Billancourt by the Air liquide company this breathing device is known today for scuba diving.

How is it possible for scuba divers to stay underwater for a long period of time? A man named Jacques Cousteau made that all possible. His invention of the aqualung made scuba diving possible, letting people explore the underwater world.

Diving is something that many consider as their hobby. This is given credit to Jacques Cousteau because he invented the Aqua-Lung. In the article “The Aqua-Lung—Bringing Ocean Exploration to New Depths” by Jess Therell, it informs readers about the invention of the Aqua-Lung and the development of the creation of this. The different inventions that are made before the Aqua-Lung was invented greatly impacted the creation of the Aqua-Lung. Some of these inventions were by Captain Yves Le Prieur and by Emile Gagnan. The contrasts between the Aqua-Lung and other inventions are that the Aqua-Lung controls with the air pressure unlike the other inventions and it can allow humans to remain underwater for a longer period of time.

Nothing functioned admirably in keeping individuals breathing until 1927, when Philip Drinker and Louis Agassiz Shaw at Harvard University conceived an adaptation of a tank respirator that could keep up breath misleadingly until a man could inhale autonomously, as a rule following maybe a couple weeks. The machine was fueled by an electric engine with two vacuum cleaners. The pump changed the weight inside a rectangular, hermetically sealed metal box, hauling air all through the lungs.

When you breathe from a SCUBA tank, the air coming out of the tank actually has the same pressure as the pressure that the water is exerting. When high-pressure gases in the air come in contact with water, they dissolve into the water. This is how carbonated beverages are made. To make carbonated water, water is exposed to high-pressure carbon dioxide gas, and the gas dissolves into the water. This is what we perceive as bubbles. If a diver stays underwater at about 30 meters (100 feet) the same amount of nitrogen will dissolve in water in his her body. Rising quickly to the surface would be like unscrewing a soda bottle releasing all the gas, this causes harsh and even fatal pain. To avoid the effects of quick decompression divers must rise

Decompression sickness, otherwise known as Bend’s Disease, diver’s disease, or caisson disease, is a very serious illness that is found most prominently in deep sea scuba divers. This is a result of nitrogen bubbles that form in the body due to surfacing too quickly. Although this doesn’t affect many people, it can be deadly once afflicted. The increased awareness of the disease throughout the years has helped in saving many people’s lives. Treatment for this condition is recommended very shortly after diagnosis.

Compressed ether machines were built in Pennsylvania by Oliver Evans in 1805 and in Australia by James Harrison in 1855, and Dr. John Gorrie in Florida built an expanding air-cooling machine in 1844. In 1851 Dr. John Gorrie created the first commercial ice making machine to cool the air for his yellow fever patients. Soon thereafter, refrigeration and freezing became popular methods of preserving foods for transport or storage, and in place where natural ice was not available.

    In 1601, Giovanni Battista della Porta described a machine that could be used to raise a column of water with the use of steam.  He described this machine in a work entitled "Spiritali."  Porta's work included a vacuum created by the condensation of steam into which water would flow.  Porta's apparatus, was called the "Pneumatica."  Porta's machine was described as being able to raise water with steam pressure.  Although Porta's machine was never applied to any practical uses, he accurately described the necessary presence of a vacuum created by steam to raise the water.
