Here are some more information for Dissolved Oxygen:

Alternative Cancer Treatments - Hyperbaric Oxygen Therapy
Hyperbaric Oxygen Therapy is a treatment which essentially involves providing the body with extra oxygen. The word 'Hyper' means 'increased' and 'Baric' refers to pressure. As we all know, Oxygen is one of the gases in the air that we breathe and is essential for life. The air that we breathe normally contains 21% oxygen. Breathing in 100% oxygen under increased pressure within a hyperbaric chamber allows extra oxygen to be forced into the blood stream and dissolved at a much faster rate than if pressure was not used. Another effect is the increased oxygen transport capacity of the blood. Under atmospheric pressure, oxygen transport is limited by the oxygen binding capacity of hemoglobin in red blood cells, which almost reaches saturation at atmospheric pressure, very little oxygen being transported by plasma. However Oxygen transport by plasma is significantly increased under HBO therapy.This extra oxygen can help where healing is retarded due to infection or limited blood supply through tissue damage.
Benefits of Hyperbaric Oxygen Therapy:
- HBO facilitates the growth of new blood vessels, enabling the transport of additional blood;
- HBO augments the body's natural defence mechanisms to fight infection and kill bacteria;
- HBO helps reduce any swelling that may occur around an area subjected to radiotherapy.
The treatment is normally painfree and is carried out in specially-designed chambers known as "hyperbaric chambers". There are two basic types of chamber: monoplace chambers and a multiplace chambers.
A monoplace hyperbaric chamber for treating one person at a time and involves the patient lying on a padded stretcher that is then slid into a clear plastic chamber about 2ft in width. Once inside, the door is closed and the chamber is pressurised.
Multiplace hyperbaric chambers can treat several people at a time. The multiplace chamber is the type most frequently used. These chambers are big enough to accommodate sometimes as many as a dozen patients at a time and it is possible to walk into them. Patients either sit on benches or lie inside these chambers. 100% pure oxygen is administered via either a mask or a clear plastic hood. HBO sessions usually last from one to three hours depending on the nature of the treatment program. Treatment sessions within the hyperbaric chamber are normally repeated over several days or even weeks.
HBO therapy is increasingly being used for helping patients who have been subjected to conventional radiotherapy treatment for cancer and are now suffering the after-effects. A major problem with radiotherapy is that, since it not only kills cancer cells but also nearby healthy cells at the same time, it can cause changes in the oxygen supply to tissues in the treated area, since less blood is supplied to the area. The result is that it becomes more difficult oxygen and essential nutrients to reach the tissues. Over a period of time these tissues can become very fragile, break down and ulcerate. Sometimes tissue can even completely die (radiation necrosis).
Studies indicate that HBO therapy can be effective in the following conditions:
- Chronic lymphoedema in breast cancer;
- Chronic radiation cystitis;
- Pelvic cancer;
- Bowel cancer;
- Prostate cancer;
- Osteoradionecrosis;
- Chronic radiation proctitis;
- Acute blood loss anemia
I hope that this brief article on Hyperbaric Oxygen Therapy has provided a brief insight into the importance of oxygen in the correct functioning of the body, plus its role not only in the treatment of cancer but also how it can be used in overcoming some of the serious adverse side effects of conventional cancer treatments. Perhaps it will encourage you to further investigate this fascinating subject. As always, you should seek the guidance of a professional medical fractioned before taking any medications or undergoing any form of therapy.

Can a eutrophic lake be improved by increasing dissolved oxygen?
I know that lower dissolved oxygen levels are a result of high nutrient levels in a productive (eutrophic) water body. I'm wondering if a system of pumping air through the lake, and thereby increasing oxygen levels, would mitigate the abundance of plant life? Or, perhaps, would the increased oxygen just encourage more productivity in the lake? I know nitrogen is a factor in eutrophication, and there is nitrogen in the air that would theoretically be pumped into the lake, but would the benefits of increased oxygen outweigh this?
Several things to keep in mind. The nitrogen in the air is N2 gas, it is not available to algae or plants as a nutrient. (To make fertilizer or a bioavailable nutrient compound, N2 must be "fixed" to form ammonia or nitrate (NH3- or NO3-.)
Second, bubbling air into ponds can be used on a limited scale, but it takes a lot of energy. Bubbling air through water is not very efficient as a method to introduce O2 into water. It is done in sewage treatment plants and in ponds where the cost is defrayed by some other value (like appearance, odor control, or fish production). But it isn't practical as a means to improve water quality on a large scale in a large lake.
Increasing Dissolved Oxygen Concentrations In Alcohol May Reduce Negative Side Effects
Oxygen for ethanol oxidation is supplied through breathing, the stomach, and the skin. There is a great deal of genetic and environmental variability in the pharmacokinetics of alcohol absorption, distribution, metabolism, and elimination. A new study has found that increasing dissolved oxygen concentrations in alcohol may help to reduce alcohol-related side effects and accidents. Results will ...
