I feel kind of sad because I wonder how many mice they drowned before they got the solution right. On the other hand it would be interesting if maybe one day something like that could allow people to live under water.
This is the Babelfish translation:
At the latest since the film Abyss is the topic liquid respiration in diver circles an eternal Mysterium and in all mouth. It admits less is that the research constantly progresses over it. The concept of the liquid respiration was invented in the 60's in the USA. Since the lung of humans grows so long it in the mother body, is filled with liquid, already for some years American scientists accepted that the gas exchange would have to be possible over liquids also, which - enriched with oxygen - are filled into the lung.
First the professional world smiled. That changed however, when a mouse was shown, which drowned in a container filled with liquid not, but swam for several minutes without signs of difficulty in breathing under the water surface. Now the liquid artificial respiration becomes a new medical option in cases offering no prospects.
The first adult patient, to who with liquid respiration in Europe the life was saved, was in the year 2000 that meanwhile 49 years old Muhrad Bukitch in the citizen of Berlin Charité hospital. Thereby the means Liquivent of the American manufacturer Alliance (maximum's group) from San Diego was used. After the conventional artificial respiration had remained unsuccessful before, it five days of long two litres of Liquivent were filled into the function-unfit lungs and thus the life was saved.
Employment in the clinical research In the department Neo Nathologie in the citizens of Berlin Charité researches for a long time a group of physicians. Their goal is the employment of the liquid artificial respiration with new ones and earlyborn. Because for the tiny lungs of newborn children the artificial respiration with high air pressures often represents a strong load for the lung and a risk. In special individual cases the liquid artificial respiration could offer a careful solution here, because thereby the artificially respirating printing could be lowered immensely.
That again makes it possible or at least probable the fact that also for very small, unreife children an employment under the aspect is possible that one late damage of this artificial respiration - one speaks of the so-called associated lung illness by artificial respiration, which bronchiopulmonalen Dysplasie - to reduce or avoid would know. Perfluorkarbon machts possible The substances used for the liquid respiration are Perfluorkarbone, relatively simple chemical compounds, which have the characteristic to have a very low surface tension. That is, they spread very well in the lung and are about twice as heavy like water. The high specific weight of the liquid substance is the secret of the artificially respirating method. Beyond that the Perflourkarbone, can take up a Kohlanwasserstoffverbindung to a considerable degree the inhaled gases oxygen and carbon dioxide. Perflourkarbone lower themselves alone by their weight without large pressure into the lung, distribute themselves there very fast into the damaged alveoli and activate them to new life. If the gas exchange is disturbed in the lung, normally conventional artificial artificially respirating respiration are used. During total lung failure has however borders. The pressures, which would have to be applied then, are so large that the lung threatens to burst. In this case the liquid artificial respiration can be used with specific disease pictures. It is beyond that also a careful method. Liquid in the lung is an unusual sight. Normally a disease picture, is it here a welfare method.
With patients with a lung failure a large part of the lung is not any longer ventilated. If one fills in a very heavy substance such as Perfluorkarbon, succeeds, opening the closed, to win not air-filled areas again for the artificial respiration thus. Already one minute immersed the American laboratory mouse into the liquid. She got accustomed to breathing under water and/or the Perfluorkarbonat completely obviously fast. What however do these results mean for dipping? At first sight regarded relatively little, there the employment of this technology so far (officially) only in the passive condition, thus under anaesthesia, to take place could. Rumor way experiment the Russian and the American military for decades also with the spontaneous respiration, thus the active liquid respiration. Since to date however still no positive results were pointed out, one must probably assume none of these test persons survived the test. As problematic in practice prove the compatibility of the liquid, which oxygen photograph capacity of the liquid, which CO2-Aufnahmekapazität of the liquid, which feeling of drowning as well as paradoxes the thorax movements as well as read but emergency leases increased flow resistance, which causes again a increased breath achievement. An application in practice is thus at present - at least on the sport dipping sector - still in far distance. How far it removes however in the military sector is, over it everyone may form its opinion.
