Opposite Of Hypoxia
Depends: Breathing difficulty can be associated with low oxygen delivery to the body and therefore the brain in multiple different conditions. Physicians can evaluate people for decreased oxygen delivery to the body through taking a history of their issues, performing physical exam, measuring oxygen saturation non-invasively as well as through other laboratory and diagnostic evaluation. ...Read more
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
Bad: Lack of oxygen in emphysema is general and not localized to one part of the body. Most critical and sensitive parts are brain and heart. If there is additional poor circulation to the legs, lack of oxygen will contribute to leg cramps, leg pain, nerve damage, poor wound healing and gangrene. ...Read moreSee 1 more doctor answer
Hemoglobin: Hemoglobin has four ligands to carry o2, i believe usually 2 used.You give o2, has dissolubility, and membrane transport to enter the cells to the hemoglobin, bind and in tissues where there is acid and low o2 tension and other factors are released to those tissues for energy processing. You give more o2 and the o2 in the plasma increases but not in the saturation of the hemoglobin due to above. ...Read more
What R the lasting effects of a years worth of reduced cerebral blood flow due to vasoconstriction?
Does the lack of proper CBF result in cell death?
Loss of Oxygen: Like any living tissue, oxygen is supplied to the heart by coronary arteries. If the arteries are blocked and a particular area of heart does not get oxygen, it may suffer lack of oxygen or death of tissue cells called myocardial infarction. There are 3 coronary arteries that supply different areas of the heart muscle. Left coronary & circumflex artery supplies leftside and right coronary, right. ...Read more

O2/ventilation/diet: Partial pressure of oxygen in alveoli is can be calculated using the alveolar gas equation. Oxygen level increases if there is a higher atmospheric pressure (hyperbaric chamber), higher inspired concentration of oxygen (using supplemental oxygen from a tank), lower co2 in lungs by breathing faster and deeper, raising respiratory quotient by eating more carbs, less fat. ...Read more
Quite variable: The effects of "low oxygen" depend on the severity and duration, as well as any underlying lung, blood or heart disease. It is best to talk to your doctor, as it can be very mild or it can cause major problems, including strain on the heart, sleepiness, poor school or work performance and behavior issues. ...Read moreSee 1 more doctor answer

That's irrelevant: You're making a common layperson's mistake: You're confusing a correlative marker with the thing itself. The presence of cerebral atrophy either during life in imaging or pathologically after death tells you nothing by itself. What matters is how well a brain WORKS, not how it looks. It doesn't really matter how the brain of someone in PVS looks. What matters is the PVS. A fate worse than death. ...Read moreSee 1 more doctor answer
