Can too much oxygen make you dizzy?

Answer 1

It is possible that an engine can run with insufficient fuel or too much oxygen. Under those conditions the valves and /or pistons can be seriously damaged.

In the past, when using carburetors, the problem was solved by using more fuel. Today's engines use EGR valves to prevent engine damage when the computer cuts back on the amount of fuel used.

Answer 2

The first relates to the concentration itself. The air we breathe is 21% oxygen. When you are breathing 2 or 3 liters per minute with your nasal cannula the concentration is between 28 and 35%. If someone is given 60% or greater 02 for more than 24hrs, it can directly damage the lungs. This is called "oxygen toxicity". This happens alot in an ICU where a critically ill person often needs high, even 100% 02 to survive. Fortunately, alot of this is not permanent if the concentration is reduced soon enough.

The second problem related to too much oxygen has to do with how we breathe. One mechanism that stimulates breathing is related to oxygen, the other to carbon dioxide (C02). If an individual's C02 level rises and remains elevated, the primary drive to breathe is the 02 level. Too much oxygen can then reduce this 02 drive, resulting in a further increase in C02 which can then produce a coma. This can be avoided with monitoring of 02 and C02 levels. This is best done with a blood gas (blood must be taken from an artery) although less invasive methods of monitoring C02 (like oximetry for 02) are becoming available.

Answer 3

The air that we breathe is just under 21% oxygen. Oxygen is essential for life, but it’s also inherently dangerous, because it results in free radicals. The same process that causes a cut apple to turn brown or iron to rust is the cause of all chronic degenerative diseases and even the aging process itself, including wrinkles, sagging skin, and age spots. This aging of the skin is an outward manifestation of oxidative damage or oxidative stress, which is occurring within every cell in your body.

Your body comprises trillions of cells. Cells, in turn, are made up of many molecules. Molecules consist of atoms joined by chemical bonds. Atoms consist of neutrons, protons, and electrons. The number of positively charged protons in the atom’s nucleus determines the number of negatively charged electrons surrounding the atom. Electrons orbit an atom in one or more shells. When the innermost shell has two electrons, it is full; when the second shell has eight electrons, it is full, and so on. Chemical reactions involve the transfer of electrons, which bond atoms together to form molecules. The number of electrons in an atom’s outer shell is an important way to determine its chemical behavior. A substance that has a full outer shell tends to be inert and tends not to react chemically. Atoms reach this state of stability by gaining electrons to fill their outer shells, or by bonding together with other atoms and sharing electrons in order to complete their outer shells.

When molecules split, they normally don’t leave molecules with unpaired electrons. But when weak bonds split, they leave one or more molecules with unpaired electrons, called free radicals. Free radicals are positively charged, very unstable, and react quickly with other molecules, to acquire the electron they need to gain stability. Generally, free radicals acquire an electron from the nearest stable molecule. The molecule that loses an electron then becomes a free radical itself, beginning a chain reaction. Once the process is started, it can cascade. Excessive free radicals in your cells can attack the cell membranes, causing cell and tissue damage. Free radicals can also break strands of DNA (the genetic material in your cells), which can lead to cancer.

A substance is oxidized when electrons are removed and reduced when electrons are added. The mitochondria in your cells generate energy by combining oxygen with glucose to gradually oxidize food in a controlled manner and store it in the form of chemical potential energy, called adenosine triphosphate or ATP. This oxidation of glucose releases energy, but it can also let free electrons escape. This process generates oxygen-based free radicals called reactive oxygen species (ROS). Anywhere from 2 to 5% of your total oxygen intake during both rest and exercise can form these highly damaging free radicals. During exercise, your oxygen consumption increases 10 to 20 fold. In turn, your cells can create more free radicals. The inflammatory response that occurs after strenuous exercise is also associated with oxidative stress. The immune system response to the damage done by exercise includes free radical production by neutrophils to remove damaged tissue.

While your body can neutralize some free radicals, all these stressors combined can be more than your body can handle, resulting in damage to your cells. On average, every cell in your body comes under attack from a free radical once every ten seconds. This damage tends to accumulate with age.

Cell membranes are made of unsaturated lipids, which are particularly susceptible to damage from free radicals, and readily contribute to the uncontrolled chain reaction. Oxidative damage can lead to a breakdown or even hardening of lipids, which makeup all cell walls. If the cell wall is hardened (lipid peroxidation) then it becomes impossible for the cell to properly get its nutrients, get signals from other cells to perform an action (such as firing of a neuron) and many other cellular activities can be affected.

In addition to the cell walls, other biological molecules are also susceptible to damage, including ribonucleic acid (RNA), deoxyribonucleic acid (DNA), and protein enzymes. Every cell contains an enormous set of molecules called DNA which provide chemical instructions for a cell to function. This DNA is found in the nucleus of the cell, which serves as the “command center†of the cell, as well as in the mitochondria. The primary site of free radical damage is the DNA found in the mitochondria. Mitochondria are the energy factories of the cell: small membrane-enclosed regions of a cell that produce the chemicals a cell uses for energy. The cell automatically fixes much of the damage done to nuclear DNA. However, the DNA in the mitochondria cannot be as easily fixed. Extensive DNA damage accumulates over time and shuts down mitochondria, causing the cells to die and the organism to age.

Answer 4

if we breath pure oxygen it will cut our lungs like knife

Answer 5

Unmonitored, increased oxygen can produce toxic effects

Answer 6

No oxygen is never harmful because when you breathe it then it has no side effects or it does not make you die.

Answer 7

No, its just when carbon dioxide is too much and goes to your brain, you'll become dizzy.....oxygen and carbon dioxide must be balance.... you will yawn if you need oxygen in your brain...XD
