What does a dialysis fistula actually do?

What does a dialysis fistula actually do?

"short circuit": A patient who is on dialysis needs the machine to clean toxins from the blood that the kidneys usually do.

This short-circuits the blood flow and the vein becomes dilated because it experiences arterial pressures. This can be used for access. ...Read more

What does it mean to have a cardiopulmonary reserve?

What does it mean to have a cardiopulmonary reserve?

Cardiac reserve: Let's make an analogy to 'army reserve'. These army men are just standby without active duty. But when there is a war, these people will be involved. Similarly, you don't use cardiopulmonary reserve during normal activities. During stress or illness, you want your lungs to take as much air/oxygen as possible and increase heart rate to maintain adequate blood flow (cardiac output) to tissues. ...Read more

How exactly does a tumor work? How does it form and what does it do that is bad for the body?

Altered normal cell: normal cells can be affected by viruses or carcinogens to develop mutations in certain genes termed "oncogenes" Certain of these genes like p53 allow cells that have a DNA mutation to slow their rate of division to allow corrections.

What do you think about cord banking? Is it worth the money? How often does a patient use it/need it?

Although it is currently possible to use them to treat some hematologic blood diseases, the promise of using stem cells to treat diseases is still mostly in the future, and has not yet proven useful in most diseases. I am cautiously optimistic that this will be useful in the future. ...Read more

What does it mean to have a dental implant "fail"?
