How does the heart get oxygen if it's the organ that pumping the blood to the rest of the body?

How does the heart get oxygen if it's the organ that pumping the blood to the rest of the body?

Oxygen: Oxygenated blood leaves the pulmonary circulation and is pumped through the left side of the heart. After it goes through the aortic valve oxygenated blood flows in both systole and diastole through the coronary arteries into the heart muscle. ...Read more

I just asked about carbon monoxide exposure, and want to know if inhaling pure oxygen or eating certain foods can rebuild my body's strength. ?

I just asked about carbon monoxide exposure,  and want to know if inhaling pure oxygen or eating certain foods can rebuild my body's strength. ?

Hyperbaric oxygen: Acute carbon monoxide (co) poisening can be treated with hyperbaric oxygen, 100% oxygen at 2-3x atmospheric pressure can displace co that would otherwise be irreversably bound to the hemaglobin. This is probably enhanced by disolving much more oxygen in the bloodstream itself than normal. This would not be helpful for minor chronic exposure like smoking. ...Read more

Muliple organ failure do u need supplemental oxygen?

Muliple organ failure do u need supplemental oxygen?

Yes: Multi-organ failure generally indicates a critical illness that affects multiple organ systems & delivery of oxygen can be compromised as lungs are generally also involved. Most patients are in the icu, on ventilatory support & continuous infusions with medications to maintain their circulation & heart function. Oxygen is the basic fuel for all cellular metabolic processes. ...Read more

Increasing blood volume with florinef (fludrocortisone) will it dilute blood and cause less red blood cells as more liquid so less oxygen to organ per beat?

Increasing  blood volume with florinef (fludrocortisone) will it dilute blood and cause less red blood cells as more liquid so less oxygen to organ per beat?

Basically no: Blood volume will increase only slightly if you dose with fludrocortisone, and hematocrit will decrease minimally and is likely to correct to normal in a few days. This is an extremely dangerous medicine unless you know exactly what you are doing. ...Read more

Can you heal or reverse brain damage cause at birth from lack of blood and oxygen to the brain with healing foods or any break through medications?

Can you heal or reverse brain damage cause at birth from lack of blood and oxygen to the brain with healing foods or any break through medications?

I'm sorry: Please forgive my frankness. Charlatans prey on the desperation of handicapped people to make money. Anyone offering you "healing foods" or some magic supplement is trying to scam you. However, there are whole practices of medicine that focus on helping folks with this kind of disability -- not with the hope of cure or reversing the tissue injury, but making life easier and more enjoyable. ...Read more

How do oxygen levels in your body affect your vision?

How do oxygen levels in your body affect your vision?

Minimally: Oxygen levels low enough to reduce vision (vision is oxygen dependent) will affect your brain and other bodily functions at the same time. The major symptoms will be those of anemia which causes pallor, fatigue, exercise intolerance, etc. ...Read more

How can you increase oxygen flow throughout your body?

Exercise: Even mild to moderate exercise encourages the blood vessels to enlarge and proliferate. These blood vessels deliver blood carrying oxygen to the tissues. ...Read more

When you are on oxygen permanently, does your body get use to a certain amount so you can't reduce the amount taken in later?

When you are on oxygen permanently, does your body get use to a certain amount so you can't reduce the amount taken in later?

Sort of.: People on long-term oxygen may be unable to keep themselves adequately ventilated without it, although this depends a lot on the condition for which they were put on oxygen in the first place. ...Read more

Why does the body need oxygen?

Cellular respiration: Oxygen is a final electron acceptor in the mitochondrial electron transport system (ets), which is a component of cellular respiration. Cellular respiration is needed for the production of Adenosine triphosphate (atp), which is the energy currency of the body. It is needed for virtually all living functions, only one of which is muscle contraction. Cyanide kills by paralyzing ets. ...Read more

How does the body use oxygen ususally?

OXYGEN for ENERGY: Biochemically, oxygen (o2) is required for energy production for every living cell. Oxygen is transported by the blood bound to hemoglobin (red pigment in red cells). Oxygen is then delivered to the cells via simple diffusion. Oxygen is taken up by the mitochondria of the cells where oxidation and phosporylation are coupled to make atp (energy molecule). Oxygen converted to h20 in process. ...Read more

Can the body adapt to low oxygen levels ?

Can the body adapt to low oxygen levels ?

Yes: Think about americans who live in denver, sherpas that live in tibet, & the maya in south america. These are populations of people who have become accustomed in one way or another to a lower atmospheric oxygen level, and in the mayans a lower blood oxygen level. Another sea-level example would be a person with emphysema who may run a blood oxygen level of 88% and still be walking around home depot. ...Read more

Spirulina good for the body I need more oxygen to the cells which other advice do you have?

Spirulina good for the body I need more oxygen to the cells which other advice do you have?

Many things: Not sure why you think you need this, but to get more oxygen first check you levels of red blood cells (RBC's)& hemoglobin- if abnormal correct as your RBC's transport oxygen. If RBC's are too big (high MCV) they have difficulty squeezing thru microcapillaries. High blood viscosity also interferes with microcirculation. See if fibrinogen is high.Thin blood with curcumin & fish oil. See my comment: ...Read more
