Aquanauts
An aquanaut is any person who remains underwater, breathing at the ambient pressure for long enough for the concentration of the inert components of the breathing gas dissolved in the body tissues to reach equilibrium, in a state known as saturation. Description The term ''aquanaut'' derives from the Latin word ''aqua'' ("water") plus the Greek ''nautes'' ("sailor"), by analogy to the similar construction "astronaut". The word is used to describe a person who stays underwater, breathing at the ambient pressure for long enough for the concentration of the inert components of the breathing gas dissolved in the body tissues to reach equilibrium, in a state known as saturation. Usually this is done in an underwater habitat on the seafloor for a period equal to or greater than 24 continuous hours without returning to the surface. The term is often restricted to scientists and academics, though there were a group of military aquanauts during the SEALAB program. Commercial divers ...

SEALAB
SEALAB I, II, and III were experimental underwater habitats developed and deployed by the United States Navy during the 1960s to prove the viability of saturation diving and humans living in isolation for extended periods of time. The knowledge gained from the SEALAB expeditions helped advance the science of underwater diving, deep sea diving and rescue and contributed to the understanding of the psychological and physiological strains humans can endure. United States Navy Genesis Project Preliminary research work was undertaken by George F. Bond, who named the project after the Book of Genesis, which prophesised humans would gain dominion over the oceans. Bond began investigations in 1957 to develop theories about saturation diving. Bond's team exposed rats, goats, monkeys, and human beings to various gas mixtures at different pressures. By 1963 they had collected enough data to test the first SEALAB habitat. At the time, Jacques Cousteau and Edwin A. Link were pursuing privat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tektite Habitat
The Tektite habitat was an underwater laboratory which was the home to divers during Tektite I and II programs. The Tektite program was the first scientists-in-the-sea program sponsored nationally. The habitat capsule was placed in Great Lameshur Bay, Saint John, U.S. Virgin Islands in 1969 and again in 1970. "Tektite III" refers to an educational project in the 1980s, using the original habitat capsule used by scientists, which was restored to be functional, but never used underwater again. Instead, it was open to visitors on dry land in San Francisco. Habitat The Tektite habitat was designed and built by General Electric Company Space Division at the Valley Forge Space Technology Center in King of Prussia, Pennsylvania. The Project Engineer who was responsible for the design of the habitat was Brooks Tenney, Jr. Tenney also served as the underwater Habitat Engineer on the International Mission, the last mission on the Tektite II project. The Program Manager for the Tektite ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Carbon Dioxide Poisoning
Hypercapnia (from the Greek ''hyper'', "above" or "too much" and ''kapnos'', "smoke"), also known as hypercarbia and CO2 retention, is a condition of abnormally elevated carbon dioxide (CO2) levels in the blood. Carbon dioxide is a gaseous product of the body's metabolism and is normally expelled through the lungs. Carbon dioxide may accumulate in any condition that causes hypoventilation, a reduction of alveolar ventilation (the clearance of air from the small sacs of the lung where gas exchange takes place) as well as resulting from inhalation of CO2. Inability of the lungs to clear carbon dioxide, or inhalation of elevated levels of CO2, leads to respiratory acidosis. Eventually the body compensates for the raised acidity by retaining alkali in the kidneys, a process known as "metabolic compensation". Acute hypercapnia is called acute hypercapnic respiratory failure (AHRF) and is a medical emergency as it generally occurs in the context of acute illness. Chronic hypercapnia, ...
