We say we are drawing from the "art" port, but often, it is not arterial blood that is drawn. Unless the person has a dialysis access in their arm, the blood drawn from ports on their chest is actually venous blood. However, for the sake of ease, we label and color the machine lines with red and blue and refer to the lines as the arterial line and the venous line.

What happens during kidney dialysis?
Toxins and waste are filtered from the kidneys
Can blood be taken from an arm with a fistula?
Yes. I get blood taken out of my arm and put back in through the fistula for "Dialysis".
Why arterial blood gas is taken from artery?
There is no such thing as arterial blood gas. When they draw blood it is drawn into a vial that has a vacuum, so it may appear that they are drawing gas, but no such gas exists. Also, when they draw blood they draw it from a vein.
What artery is blood taken to the kidney in?
The left and right renal arteries branch off of the abdominal aorta and bring arterial blood to their respective left and right kidneys.
What is the difference between sp02 and sa02?
SpO2 (peripheral capillary oxygen saturation) is a measurement of oxygen saturation in the blood using a pulse oximeter on the finger, while SaO2 (arterial oxygen saturation) is a measurement of oxygen saturation specifically in arterial blood, usually taken from a blood sample. While SpO2 is non-invasive and provides a quick estimate of oxygen levels, SaO2 is more accurate but requires a blood sample and laboratory analysis.
What is a dialysis technician practice test and how many times a year is this test taken?
A dialysis practice test is taken to ensure that you have the retained the knowledge you learned in college regarding dialysis. You need to take this test just once a year.
Why alveolar oxygen tension is more than arterial oxygen tension?
The alveoli are the site of gas exchange in the lungs, where oxygen is taken up by the blood. The alveolar oxygen tension is higher than arterial oxygen tension because there is a gradient that drives oxygen diffusion from the alveoli into the blood. This difference is necessary to ensure efficient oxygen uptake by the blood in the lungs.
Can blood pressure be measured in the leg?
Yes it can with an automatic b/p cuff however a blood pressure taken in the arm (assuming there are no problems like past stroke or dialysis shunts) is usually more accurate.
How much blood is taken out during a flobotomy?
alot darn it
Does marijuana get dialyzed out?
No, not completely. Delta 9 THC, the active ingredient in cannabis, is taken up by many types of cells, including fat cells (adipose tissue). In heavy users, THC is released from adipose tissue over time, sometimes as long as several weeks (that not even dialysis can completely get rid of).
Precautions to be taken during blood transfusion?
sterilization of equipments, compatibility of blood types,etc
How do renal insufficiency may be corrected by the use of Dialysis?
dialysis works just like our kidneys. if for some reason our kidneys fail to filter our blood, then dialysis is done. in dialysis our blood is filtered to remove waste products. dialysis can be done in two ways haemodialysis---it makes use of a kidney machine or artificial kidney containig a fluid with adjusted compostion. during this process the blood i pumped from the body through a tube into the fluid through a semi permeable membrane present in the fluid. this way by passing through the semi permeable membrane the nitrognenous wastes and excess salts are diffused out from the blood into the fluid. then the blood is returned into the body. this proces takes 6 to 10 hours and is to be done three times a week peritoneal dialysis----it requires abdominal incision . a cathetar is inserted through this incision inot the peritoneal cavity. a fluid bag is attached to the cathetar from the outside. in this way the fluid enters the peritoneal cavity of our body and purifies our blood. after sometime the fluid is tkane out of the peritoneal cavity back into the bag. this process takes an hour and is reapeated day or overnight the major difference between the two dialysis processes is that in the first process the blood is taken out of our body and then filtered.it is a long and lengthy process and very painful while in the second process the fluid itself is inserted into our our body and then blood is purified. this is a realtively quicker way
