How are hypoxia and hypoperfusion different?

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

Hypoxia (Definition)

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 ...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. If the oxygenation goes low enough as in sleep apnea, then there is hypoxia, or in people who have lower oxygen level to start with like copd. ...Read more

Please explain why vasoconstriction happens in hypoxia?

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?

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

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

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
