- Dialysis
- Key points
- substitute for many normal duties of the kidneys
- clean blood and remove waste products
- balance water and salt to balance fluid in the body
- control blood pressure
- help make red blood cells and strong bones
- work on osmotic gradient
- allows patients with kidney failure to live productive lives
- patients have to choose the type of dialysis that best match heir needs
- substitute for many normal duties of the kidneys
- Haemodialysis
- shunt in forearm vein with bridge to artery
- shunt connected to dialysis machine
- osmosis
- move from high concentration to low concentration through semi-permeable membrane
- fluid drip
- in the machine, blood cells and protein are kept and toxins are removed
- constantly drawing waste out
- concentration gradient
- constantly drawing waste out
- clean blood goes back into artery
- blood constantly flowing through machine
- more common
- go to unit 3 times a week
- 2 1/2 to 4 1/2 hours
- blood pressure checked during procedure and machine altered
- Peritoneal
- peg in peritoneal sack
- blood is purified inside body using peritoneum
- natural cavity
- abdomen filled with diasylate (dialysis fluid) via catheter
- lower concentration than blood
- osmosis
- around 50% of toxins in blood move in to fluid until concentration gradients are the same
- fluid removes water and toxins from blood through peritoneum
- goes back into the bag
- dirty fluid drained out and replaced by new clean fluid
- not as effective as haemodialysis
- Key points
