I've been at 3500 feet for 3 days. Been having chest tightness and shortness of breath and Oxygen says 92-95 usually 98. BP 115/75. I felt sick on plane too. Previous heart check was good. Norm chest X-ray. Nobody else has low oxygen here but me.?

Mgt.: A virtual inbox consultation is advised, so that you can upload diagnostic study reports for review. You should have close follow up, and if the symptoms worsen or involve any neurologic symptoms, please see the ED. Please monitor your Respiratory effort, and if you are having difficulty, proceed to the ED.

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 ...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

Does hypoxia cause vasoconstriction or vasodilation?

Vasoconstriction: Low oxygen cause blood vessels to constrict. The body is trying to use whatever oxygen is available to maintain critical body functions and constrict blood flow to others. ...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

What is the definition or description of: hypoxia?

Low Oxygen Supply: 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). ...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

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?

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

Wheezing Infant: Bronchiolit describes lower respiratory infection in young children, caused by virus, main symptom is wheezing. Most w/ bronchiolit do not become hypoxic, highest risk are less than 6 mos, history of prematurity or chronic lung disease. When present, hypoxia usual present in early stages of illness. Hypoxia is treated with oxygen therapy that can take several dys to wean. Illness can last 2-4 wks. ...Read more

Could you give me a simple explanation on the relationship of hypoxia to asphyxia?

Choking: Asphyxia is the lack of ability to take in air as in choking, drowning due to water occupying space where air should be or simple occlusion of the airways so no air gets in, obviously leads to lack of air and oxygen and yes, hypoxia as the blood has no oxygen to pick up. ...Read more

If mild hypoxia stimulates respiration, why does severe hypoxia depresses the same?

Hypoxia: Oxygen is required for tissues to burn their fuel, just like a fire burning a log. The human system can compensate for mild low o2 by breathing faster, equal to u blowing on the fire to help it burn. If the o2 is so low breathing faster doesn't get enough or the body becomes exhausted in the effort, the metabolism shuts down, equal to the fire going out. ...Read more

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

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
