Medical treatment oxygen

There are no specific methods available to reduce the absorption of hydrogen sulfide following exposure. Supportive treatment includes artificial respiration if respiration is depressed administration of oxygen and standard medical treatment for eye irritation, pulmonary edema, seizures, and hypotension (Sorokin 1993). 

Medical treatment of acute and delayed symptoms consists of immediate 100% oxygen followed by hyperbaric oxygen (Myers et al. 1985). Rapid treatment with hyperbaric oxygen frequently prevents neuropsychiatric sequelae (Norkool and Kirkpatrick 1985). Psychiat-... 

The separation of oxygen from air is extremely important in connection with medical treatments, combustion processes, etc. Relatively thin effective membrane layers are required for practical oxygen separation systems, because the permeability coefficients of oxygen of most polymers are lower than those of hydrogen and carbon dioxide. 

The oxygen enricher thus prepared was used for the medical treatment of patients who had lung diseases. It was recognized that the effect of the enricher was equivalent to that of pure oxygen gas at 0.61/min. An organosiloxane membrane which can behave as an elastic valve , changing the pore size reversibly according to the pressure applied, was also prepared [71]. 

Air enriched with 40 % oxygen is necessary for medical treatment of asthma. For this kind of therapy, poly(4-methylpentene-l) and poly(2,6-dimethylphenylene oxide) are applied, for which the FO2 and o values are, 3.23xl0-9cm3(STP) cm/cm2-sec.cmHg, 4.1 1.58xl0-9cm3 (STP)-cm/cm2-sec-cmHg, 4.2, respectively. 

But these two gases have a great many other uses as well. Oxygen is used to produce stronger steels less expensively. It is also used together with acetylene and other fuel gases such as propane to weld or cut steel in fabricating structures and machinery. It is used in medical treatment and respiratory therapy. 

In the past, hyperbaric oxygenation as a medical procedure has received considerable attention. In this treatment the patient is given pure oxygen and may be placed in a pressurized chamber. In effect, the patient may thus receive >400 kPa (>4 atm) of pure oxygen. Beneficial results in cases of carbon monoxide poisoning, gangrene, severe bums, and other difficulties are often achieved as a result of this treatment. 

Selected physical properties of oxygen are included in Table 9.24. It is a colourless, odourless and tasteless gas which is essential for life and considered to be non-toxic at atmospheric pressure. It is somewhat soluble in water and is slightly heavier than air. Important uses are in the steel and glass industries, oxyacetylene welding, as a chemical intermediate, waste-water treatment, fuel cells, underwater operations and medical applications.
