Oxygen is essential for life. It is absorbed via the lungs (see RESPIRATION) and is transported by HAEMOGLOBIN within the ERYTHROCYTES to the tissues. Within the individual cell it is involved in the production of adenosine triphosphate (ATP), a compound that stores chemical energy for muscle cells, by the oxidative metabolism of fats and carbohydrates. HYPOXIA causes anaerobic metabolism with a resulting build-up in LACTIC ACID, the result of muscle cell activity. If severe enough, the lack of ATP causes a breakdown in cellular function and the death of the individual.
When hypoxia occurs, it may be corrected by giving supplemental oxygen. This is usually given via a face mask or nasal prongs or, in severe cases, during ARTIFICIAL VENTILATION OF THE LUNGS. Some indications for oxygen therapy are high altitude, ventilatory failure, heart failure, ANAEMIA, PULMONARY HYPERTENSION, CARBON MONOXIDE (CO) poisoning, anaesthesia and post-operative recovery. In some conditions – e.g. severe infections with anaerobic bacteria and CO poisoning – hyperbaric oxygen therapy has been used.... oxygen
– from anaerobic metabolism which is ultimately oxidised after conversion to citrate and metabolism via the citric acid cycle. The increased amount of oxygen above resting concentrations which needs to be consumed to perform this metabolism is known as the oxygen debt or de?cit.... oxygen deficit
Lead disrupts neurotransmitters in the brain and disposes to nervous excitability, aggression and hyperactivity. Aluminium is associated with senile dementia and Alzheimer’s disease, accumulating in the brain. Cadmium induces changes in behaviour with reduced mental ability. Mercury is present in the amalgam used in dental surgery as part-filling for teeth. Arsenical poisoning may occur in food contamination or paints.
An internal chelating or cleansing of tissues of the lungs, urinary system, blood and lymph may be assisted by a combination of relative expectorants, diuretics, hepatics and adaptogens among which are: Barberry, Blue Flag root, Chaparral, Burdock, Echinacea, Red Clover, Yellow Dock. To bind with metals and assist their passage through the intestinal canal to the outside of the body: Irish Moss, Iceland Moss or Slippery Elm. Garlic.
The Medicines Control Agency of the Ministry of Health (UK) has given consideration to the content of heavy metal impurities and rules that a limit of 75 micrograms of total heavy metals shall be the acceptable maximum daily intake.
Licence-holders are required to carry out tests on all incoming material. Some seaweeds may be heavily polluted with mercury, arsenic and radioactive particles as a result of micro-biological contamination. The MCA requires Bladderwrack and other seaweeds to contain minimum levels. ... heavy metal toxicity

This is achieved by placing a person in a special chamber and exposing him or her to oxygen at a much higher atmospheric pressure than normal.
