What is the name of the machine that is use instead of kidneys to fill the blood?
Foremost thing that you need to know is that Kidney DOES not pump blood. Heart does. Kidney purifies blood and makes urine. Artificial kidney action is done by a process called dialysis. The machine is generally just called Dialysis machine.
How do you calibrate the heart lung machine?
run the machine and look after the tube rating... and placing the roller pump at its position just measure the drop through it
What are physiological processes are involved in dialysis?
hunulity process occur in dialysis because it helps pump the blood stream
How is Hemofiltration performed?
uses an ECC. A hollow fiber hemofilter is used instead of a dialyzer to remove fluids and toxins. Instead of a dialysis machine, a blood pump makes the blood flow through the ECC
How does a kidney dialysis machine filter blood?
The dialysis machine is really a 2-part machine, serving two basic functions. First it acts as a blood pump, and second, it pumps a solution known as dialysate. The machine has a very accurate metering system that combines ultra-purified water, bicarbonate, and a potassium "bath" together. The patient is hooked up to the machine via what is known as the extra-corporeal circuit (meaning outside of the body) via two large-bore needles (or a semi-permanent central catheter). The lines go to the machine, and into a pump. No blood actually goes into the machine, but rather stays in the blood tubing. There is a larger diameter section of the line that fits in the blood pump, and the pump moves the blood by squeezing the larger section of the line at regular intervals. The blood comes from the patient through the pump, and into the artificial kidney (the dialyzer). The dialyzer is made of thousands of microscopic fiber tubes. These tubes can be likened to drinking straws that have small holes punched in the sides of the straws. These holes in the fibers are too small to allow the blood cells to pass through (much like a colander will let water out, but not your spaghetti noodles). The dialyzer is hooked to larger hoses that flow the dialysate through the area around the fibers in the dialyzer (usually in the opposite direction from the blood flow), and by pressure and osmosis, the fluid around the cells in the blood that contains the urea (waste) passes out of the blood and into the dialysate and to the waste system (drain). Dialysis is only about 10% to 15% as efficient as a working kidney, so patients need to dialyze frequently (usually 3 times per week or more, usually for 3 to 4 hours per treatment). Also, because of this, their blood levels of essential electrolytes like potassium, calcium, and sodium, as well as phosphorus, vitamins and other essential minerals must be continually monitored because they are lost during dialysis. Additionally, most patients need a drug to stimulate the production of red blood cells. A drug called Epogen is commonly used. It is very expensive, as much as $1000 USD to $2000 USD per shot, usually at each treatment. Many patients can gain 2 to 4 kilograms of fluid weight (4.4 to 8.8 lbs) in only 2 days. Access to the patient is usually gained through what is known as a fistula. A surgeon ties an artery to a vein, and this makes the vessel grow very large, sometimes as large in diameter as a thumb (or larger). This is done because the patient has to have needles inserted every other day as long as they are on dialysis. The machine monitors many parameters such as the blood flow, dialysate flow, arterial and venous pressures, the conductivity of the dialysate solution, the temperature and pressure in the artificial kidney (dialyzer) and will set off an alarm if anything is out of normal parameters.
What types of pumps are used in heart-lung machines?
A pump is required to produce blood flow. Currently, roller and centrifugal pump designs are the standard of care.
What machine uses power to water?
a pulley a pump
How many g.p.m. does a washing machine pump?
There is no set answer for that. It will depend on the make and model of the washing machine.
What is a pneumatic machine?
a pneumatic machine is a machine that uses gas usually air, to transmit a force and do workexamples: a pump for a bicycle, and a drill
How do you take care of kidneys?
You watch what you eat and don't smoke. Go see a nephrologist often if you have a kidney disease. Deal with bladder infections quickly. Also, you should urinate when you need to. Don't hold it in, or else you will cause your kidney to fail, and everyday, you will need a machine to take the blood out of one arm and pump it into another. This is a 2 hour process.
How do you cure renal problem?
If someone is in ESRD, or End Stage Renal Disease, there are several options that their doctor should discuss with them. First, they would obviously treat a patient in ESRD with dialysis, whether in acute (sudden onset, sometimes reversible with dialysis treatments) renal failure or chronic (disease induced, not revisable. Once the patient is stable, the renal team would educate the patient with some other options. Hemo-dialysis, (hemo-blood)- Hemo- dialysis is the most common dialysis treatment because it is the fastest way to treat and stabilized a patient. Once the nephrologist has diagnosed kidney failure and dialysis is immanent, a temporary catheter is usually placed in the jugular vein for a quick access. The dialysis team connects plastic tubing to the catheter and is able to clean the patients blood of toxins and remove excess fluid. If the patient has Chronic Renal Failure, then the Nephrologist and renal team will educate the patient and family of their options. A graft (artificial artery) or a fistula (the patients own artery), which is a permanent access, is placed in the patients arm. A fistula takes anywhere from 6-12 weeks before it's 'mature' enough to use for dialysis, and can last anywhere from 1- 20 years. A graft is usually ready within 1-2 weeks but generally lasts for only 2 years, although, some have lasted longer. The permanent accesses are used or 'accessed' by two, arterial and venous needles, each treatment. The first (arterial) needle is connected to the arterial side of the dialysis tubing, where the blood is pumped through the tubing to an artificial kidney, or dialyzer. The blood is filtered, then the 'clean' blood is returned through the venous side of the dialysis tubing, which is connected to the second (venous) needle. This process is repeated simultaneously by a pump for several hours until the blood has been cleaned of most toxins. Each treatment time is determined by how clean each patients blood gets during one treatment. The second option might be peritoneal dialysis, aka CAPD. This type of dialysis is done through a catheter which is placed in the peritoneal cavity of the abdomen. The port is permanently placed, but is discretely hidden by clothing. A solution is infused through the port and is left to 'dwell' in the peritoneal cavity. After a period of time, the solution is drained. There is considerably more time to do other activities and a patient might be able to continue to work. The third option is kidney transplant. Whether a family member or friend (living donor) decides to donate a kidney, or a kidney is donated from a cadaver (a non-living donor), the organ must be 'matched' to the patients blood type. If there is a match the patient can receive a transplanted kidney, which can last approximately 2-10 years. Although, there are anti-rejection drugs that have to be taken daily and are a expensive, this is option that is most like a natural kidney.
