Hypoxia (Overview)

Hypoxia, is a condition in which the body as a whole or a region of the body is deprived of adequate oxygen supply. It is classified into 4 groups: - hypoxemic - oxygen is low - anemic - decreased ability for hemoglobin to carry oxygen. - ischemic - decreased blood flow. - histotoxic - oxygen is reaching the cells, but the cells are unable to use the oxygen (cyanide).

How does hypoxia related hyperpnea affect abg's? Had gases with normal ph, pco2 low, po2 also low, hco3 20. Rr was about 36, saturation 97. Nonsmoke

Lung and kidney: If one has hypoxia, that is most likely due to damaged lung unable to pick up more o2. When someone breathes fast there is low co2, as it is breathed out. Co2 + h20 becomes h2co3 and in the kidneys become h and hco3 (bicarbonate) but since co2 is low hco3 is also low (the product) and this is the balance of the ph so ph is either normal or basic (high) due to co2 elimination by breathing. ...Read more

How does pulmonary edema after heart bypass occur? Dad died 3 days after HB due to this, before he was put on vent he showed signs of hypoxia. Why?

How does pulmonary edema after heart bypass occur? Dad died 3 days after HB due to this, before he was put on vent he showed signs of hypoxia. Why?

Usually heart failur: The most common (but not sole) cause of pulmonary edema is heart failure. When the pumping function of the left side of the heart fails, fluid backs up into the lungs. That is pulmonary edema. It causes shortness of breath associated with low amount of oxygen in blood. If the bypass failed to improve dad's heart function that could have been a cause. MANY other causes are possible. ...Read more

What does it mean if you have low oxygen levels in your blood tests?

Lung disease: Is the commonest reason for a low level of oxygen in the blood. It can also happen in heart disease if the heart is failing and fluid builds up in otherwise-healthy lungs, or if there is a hole in the heart, causing blood to bypass the right heart circulation into the lungs and skip picking up oxygen there. These are examples of some common causes. Smoking, high altitude=examples of lung reasons. ...Read more

Do you know how a short period of hypoxia at birth could affect a child?

Do you know how a short period of hypoxia at birth could affect a child?

Minimal effect: Short periods of low oxygen at birth are not likely to have long term effects. As baby transitions into the first hour or two of life, they come from an environment (womb) where their o2 level was low by adult standards (70's) and modern devices often show quick drops below 50 during birth for brief periods. Those likely to show problems will often have a seizure ~24hrs reflecting injury. ...Read more

Can anxiety cause hypoxia, lack of oxygen problem?

Many things.,,: Hypoxia refers to a decreased level of oxygen in the body. Many conditions can result in hypoxia including, but not limited to, lung conditions like acute asthma, copd, pulmonary embolism, etc., cardiac conditions like congestive heart failure, acute mi, valve abnormalities, etc., musculoskeletal conditions like als, diaphragmatic paralysis, etc. Hypoxia can lead to anxiety! ...Read more

What is hypoxia and what does it mean if my doctor said I have a slight case of it?

Hypoxia: Hypoxia means lower levels of blood oxygen compared to normal values. It could be caused by by diminished absorption of oxugen in the lungs (asthma, pneumonia, drowning, etc) or obstruction of blood flow in the arteries (arteriosclerosis, embolism, thrombosis) or in the veins (congestive heart failure, embolism, thrombosis, etc). ...Read more

How can I prevent lack of oxygen in my eyes?

Not a problem: The front of the eye gets its oxygen directly from the air. Contact lenses can diminish this but modern designs minimize this problem. If you are having trouble getting oxygen to the back of the eye, then you have a major circulatory system problem which needs cardiac attention. ...Read more

Can anyone explain the biology of tissue hypoxia?

Lack of oxygen: Tissue hypoxia means not enough oxygen is being delivered to the tissue in question. This may occur for many reasons including lung problems, heart problems, circulation problems or obstruction of the airway (as in sleep apnea) treating the underlying cause is ideal; supplementing with oxygen may also be helpful. ...Read more

Please explain what are some symptoms of hypoxia?

Low oxygen: Hypoxia is the low tension of oxygen, hypoxemia is low oxygen tension or amount in the blood, desaturation is low measured oxygen occupying the red blood cells. When there is hypoxia, there is air hunger, so a person will breath harder to catch air, there is dyspnea. The signs could range from cyanosis or bluish skin or nail beds, confusion, unconsciousness or frank heart attack. ...Read more

Could you explain sleep hypoxia?

Hypoxia: All of us do have some degree of decreasing our oxygen level and some desaturation during sleep, due to depression of the respiratory center and by weight of our chest and lack of effort some degree of atelectasis.

How are hypoxia and hypoperfusion different?

Blood flow: Hypoperfusion is the lack of adequate blood flow. Blood carries oxygen. If there is hypo perfusion then hypoxia can occur. On the other hand, even if there is good blood flow if there is not enough oxygen in that blood there is still hypoxia both in the blood measured for oxygen and in the tissue getting perfused. ...Read more

Please explain why vasoconstriction happens in hypoxia?

Not whole body: In fact more parts of the body will have vasodilation, as in organs and muscles you then resort to anaerobic respirations which causes Lactic Acid production and causes vasodilation. The skin on the other hand thee may be vasoconstriction to preserve the flow of oxygen to the essential organs. ...Read more

My husband was told he is hypoxic following his pneumonia. What could might cause this hypoxia?

My husband was told he is hypoxic following his pneumonia. What could might cause this hypoxia?

Depends: If your husband is still hypoxic after being discharged, I would believe that he is on home oxygen (i hope). Nevertheless, if he is still hypoxic, I could mean that his lungs are still in the process of healing and clearing out the pneumonia or that he has sustained damage (scarring) and that affected part of his lung (s) is not able to exchange gases (o2 and co2) anymore. ...Read more

Greeting's. I was wondering after living with beh'cet's syndrome for over 15 years and now having hypoxia? Related to pfo, would repair b worth it?

Possibly: This isn't easy to answer since there are other considerations. Is the pfo related to pulmonary hypertension? Do you have other reasons to be hypoxic? There certainly can be good reasons to fix a pfo, but you should discuss this with your doctors and even get a second opinion so you can feel confident you're making a good decision. ...Read more

Explain hypoxia vs hypoxemia?

Tissues vs. Blood: Hypoxia is low oxygen in the tissues. Hypoxemia is low oxygen in the arterial blood. Hypoxemia caused by low oxygen in air (such as high altitude), low ventilation (slow breathing oversedation), lung disease or blood clots in lung. Low oxygen in arterial blood leads to low oxygen in tissues but hypoxia can also be due to anemia (less oxygen carrying capacity by blood), carbon monoxide poisoning. ...Read more

What are the long term effects of congenital hypoxia?

Depends on variables: Hypoxia at birth is relative, as all babies have lower oxygen content in the womb before delivery & the slower metabolism of the unborn is able to tolerate it. After delivery, baby works to breathe, maintain their heat & blood sugar & must increase their blood oxygen content. The duration of any oxygen deprivation after delivery effects amount of injury from none to lots. It takes time to tell. ...Read more
