What happens when you do not get enough oxygen in your blood?

Answer 1

If there were no oxygen where you are, you could lose consciousness or even die.

Oxygen is a crucial requirement of the human body. However if for some reason the oxygen is depleted around the body, then a person will begin to breathe more heavily as the body tries to compensate. The heartbeat will normally increase to carry any available oxygen more quickly. Then various body systems, including the higher functions of the brain, will stop in an attempt to use what little there is for critical brain processes.

Answer 2

Your body relies on a vital process called cellular respiration in which oxygen and sugar are converted into carbon dioxide, water and ATP the body's energy molecule. When there isn't enough oxygen in the blood the body cant complete the process of cellular respiration in its cells which then begin to die.

Answer 3

Many chronic lung conditions cause decreased O2 blood saturation levels. Emphysema, Black Lung, and other serious lung conditions create a reverse effect in the brain. The normal decrease-O2 feedback mechanism changes to carbon dioxide, meaning, the brain becomes accustomed to lower O2 and higher CO2. If you give a person with certain severe lung diseases higher oxygen of 8L/min, you can kill them, but if you keep the delivery of external O2 lower at 2/Liters/per minute, you can help the person stay alive. Eventually, though, this warped feedback mechanism in Emphysema fails... no matter the supportive therapy...and the person's lungs stop working altogether.

In normal, healthy individuals, the brain tries to keep all the organs perfused with oxygen enriched blood. Heart and Lungs try to compensate. If low O2 persists, it begins to affect consciousness as the body starts trying to lower the energy needs for O2, like shutting off lights in your house to conserve electricity. If the normal O2-CO2 mechanisms cannot be maintained, the body shifts to keeping the VITAL organs working, even if it must sacrifice peripheral structures. Without supportive therapies and medications, the person can lose fingers, toes, part of feet or legs because the blood has shifted to keeping internal organs perfused first. If it gets to that stage with no corrections, the person will likely die.

And finally, in another scenerio, if all O2 is suddenly stopped, the person will lose consciousness. If the cause is suffocation, the person will die. If during a fire, the brain cannot use chemicals a fire creates-- the person will die from smoke and toxic chemical(s) inhalation. If from near-drowning, the person will lose consciousness but breathe in water/fluid. The water or fluid breathed in will cause an water bubble to the brain; if revived quickly, the person can survive but often with impairments. If not revived quickly, the brain cannot survive without O2; the lungs will fill with water, stopping respirations and causing cardiac arrest.

All of these descriptions are generalities. A lot more goes on internally between the moment of deceased O2 and its possible outcome(s).

Answer 4

that limb of your body would actually end up dying and may come detatched depending on how much oxygen is cut off

Answer 5

Cells need oxygen to survive. This oxygen-rich environment is known as an aerobic environment. Oxygen-depleted cells die out.

Answer 6

Ultimately death

Answer 7

You suffocate and die.

Answer 8

You yawn.
