Question 1

is it normal when the space between frontal brain and the bone is much bigger than the space between parietal/temporal brain and the bone. can it be a sign of birth hypoxia?

Accepted Answer

No: Hypoxia refers to lack of oxygen.

Question 2

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?

Accepted Answer

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.

Question 3

what is hypoxia?

Accepted Answer

Decreased oxygen: Hypoxia is a medical term for a decreased amount of oxygen in the blood.  There are many reasons this can happen but it is a problem that requires evaluation and treatment.

Question 4

what is a concept map of hypoxia?

Accepted Answer

Lack of oxygen: Lack of oxygen can happen from 1.) high altitude 2.) inadequate ventilation into the lung 3.) airflow obstruction 4.) ventilation and perfusion mismatch and 5.) impaired or loss of surface area in the lung.  All causes of low oxygen (hypoxia) can be fit into one of these 5 categories.

Question 5

how can hypoxia cause cell damage?

Accepted Answer

Hypoxia: Every cell in the body needs oxygen to function fully. Lack of oxygen will kill it.

Question 6

how long does hypoxia take to heal?

Accepted Answer

Complicated: It depends on the circulatory and pulmonary system, and the oxygen in the ambient system.

Question 7

please explain what are some symptoms of hypoxia?

Accepted Answer

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.

Question 8

can anyone explain the biology of tissue hypoxia?

Accepted Answer

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.

Question 9

what is the definition or description of: hypoxia?

Accepted Answer

Low oxygen: Hypoxia means that tissue is not getting enough oxygen. This can either apply to the whole body, in which case there is too little oxygen in the blood, or it can apply to just specific organs or tissues.

Question 10

could you explain sleep hypoxia?

Accepted Answer

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.
