4 reasons why a person would use oxygen??

1--during anesthesia & post-op\n2--cardiac diseases\n3--respiratory diseases\n4--non-breathing person

its where the blood picks up the oxygen.

The mechanism that drives a human to breath is dependent upon CO2 receptors in the body--both peripheral chemo receptors and central chemo receptors. As with all receptors in the body (excluding pain receptors) they will adapt when exposed to a stimulus over a long period of time. A person known to retain CO2 has long since been exposed to elvated CO2 levels and the CO2 receptors have adapted.  For this type of patient--their drive to breathe is no longer driven by elevated CO2 levels. They rely primarily on oxygen sensitive chemo receptors. (When the oxygen level in the arterial blood--PAO2 falls below 60mmhg-it will tell the respiratory control centers in the brain to initiate respiration.) Administering high levels of oxygen to an individual such as this can be harmful and dangerous. High levels of supplemental oxygen raise the PAO2 levels--therefore the oxygen chemo recptor never sends the signal to the respiratory center to breathe. This will knock out the patients only remaining chemical signal to initiate respirations. \nIf your goal is administer a medication via a nebulizer (ie the standard one on the market) the use of moderate flow (5 LPM) of oxygen should not significantly elevate the PAO2 levels. The nebulizer is not a closed system and therefore is mixed with room air the only has an oxygen concentration of 21%. Ideally, the use of compressed air is utilized for such treatments.

Breathing is a process of intake of gases, and exhalation of unwanted gases. the oxygen comin through inhalation, is used for oxidation of glucose, which gives you energy by which your body can perform actions, like metabolic reactions, growth, movement of muscles etc

Because oxygen is rapidly being used to keep your body going,and less of the oxygen gets to your head as usual.

This would actually be a pretty bad idea. Hydrogen peroxide is toxic to cells and can be the source of oxygen free radical species. Your body actively tries to stop precisely this from occuring by using antioxidant molecules to prevent damage to DNA. If you are looking to get more oxygen to your individual cells there are several mechanisms by which O2 arrives at the cellular level. A)increase blood flow = more O2 to cells (ie. improve your heart health by exercising aerobically) B)increase O2 carrying capcity = more O2 per blood cell means more O2 to the other cells. You can accomplish this by eating right, getting enough iron in your diet and again, exercising regularly. C)increase O2 intake = try pure oxygen therapy at a spa or oxygen bar. This will allow you to breath high concentration oxygen and put more O2 in your system. Lastly D)increase your total number of red blood cells. This can be accomplished by moving to higher elevations where low O2 concentrations make your body adapt physiologically by making more red blood cells. Many athletes train at elevation to improve their aerobic performance temporarily for competitions. Hope this helps!

COPD is caused from smoking.  Why remove something that is putting oxygen in the air when you are breathing it out?
259818
lots of things, chemicals, stress, trauma, lack of oxygen, lots and lots

b)less,because while you exercising your lungs needs more extra oxygen,makes your body need to breath more air

Good info Klaus, but you mostly are discussing decompression, in which dissolved gases (usually nitrogen) bubbles out of the blood when going from high to low pressure-Not the reason oxygen is toxic.  The blood requires a certain pressure of oxygen, in other words, and certain number of molecules.  The normal concentration of oxygen in the atmosphere is about 21%, which of course is about perfect.  If you are in an environment that has twice the pressure, you require oxygen at half the concentration, or about 10%.  Its still the same number of molecules total, just a lower concentration.  Clearly, if you are in an environment of 10X the pressure compared to sealevel, you only need a concentration of oxygen of about 2%...again, its still the same number of molecules of oxygen, but because of the greater pressure, there is a lot more total gas molecules present.  Oxygen is a highly reactive molecule, and causes (obviously) oxidation...such as rust on iron.  In the body, this is a toxic effect-More to the point, though, is that the body requires a certain amount of carbon dioxide to maintain the proper acid-base balance.  If far too much oxygen is given, it swamps the ability of hemoglobin to bind CO2, thus causing acidosis-the acidification of the blood.  So, the deeper you dive, the lower *percentage8 of oxygen you require (though again, its the same *amount* of oxygen)- the oxygen is replaced by the most inert gas that can be obtained-helium usually.

apo2_99 is wrong, you do sweat, but your in a pool so who cares.  but there are many advantages.  good for cardiocascular stuff, both aerobic and anaerobic activity.  stretches out your muscles, relieves stress, helps you sleep, keeps you in shape/ gets you in shape.  very fun.  good way to avoid drowning.  and just by learning to swim, you'll be a better swimmer than 95% of the world, so that is cool.

When oxygen combines with combustible material, such as carbon, a great deal of energy is released.  You and I get our energy from these reactions (and life depends on energy).  However, not all life on earth uses oxygen for energy.  Anaerobic bacteria, for instance; the name means "no air", and oxygen kills them.\n\nAlmost all the oxygen in our atmosphere was originally released by living things, and it was poisonous to the first life!  One of the most remarkable things about using oxygen is that Life adapted to what was originally a deadly poison, until it became a necessity.
