What Is A Home Dialysis Unit And How Does It Work
Simple answer is that it is a medical technology used primarily to provide an artificial replacement for lost kidney function in people with renal failure. Hemodialysis remove wastes and excess water from the blood by circulating blood outside the body through an external filter, called a dialyzer. Blood and dialysate flow through in opposite directions and the ...Read more
Blood cleaning: Blood is pumped into a filter that allows toxins to pass into a salt solution that carries them away while delivering bicarbonate (sodium bicarbonate) and other needed minerals. Excess fluid can be removed with the filter also, the blood then returns to the patient without the toxins, with less water and with corrected acid base status. ...Read more
Artificial kidney: The principle of dialysis machine is hard to explain in 400 characters. Like a human kidney, it filters impure blood under pressure; excess water is removed; blood toxins (prea, phosphorus, and many others) diffuse out in to the dialysate (the clean artificial fluid put in to the machine); some electrolytes might diffuse back in to blood. The relatively clean blood diffuses is returnd to the patnt. ...Read more
Helps pts urinate: Its a catheter inserted thru the urethra into the blader. Its used to collect urine for testing, for obstructions in pts who can't otherwise urinate, and to accurately asess total volume of urine out put in pts over a 24 hr period.Some hospitalized pts are too weak to get up and go to the bathroonm or even use a bed pan .These pts would also qualify for a foley. ...Read more
Removes waste, fluid: Dialysis takes over two important functions of the kidney: removing waste products & removing excess fluid. There are two basic techniques: hemodialysis and peritoneal dialysis. In hemodialysis, blood is removed from the body, circulated through a filter much like an oil filter, and returned to the blood stream. Peritoneal dialysis uses the peritoneal membrane in the abdomen. ...Read more
See below: Brain biopsy is an uncommon procedure to diagnose brain disorders like tumors, dementia and suspected infections not otherwise diagnosable. The tissue is examined by a pathologist to arrive at a diagnosis. See this site for more info. http://www.healthline.com/galecontent/brain-biopsy. ...Read more
It doesn't: I wouldn't think of a detox or cleanse as a way to lose weight in a healthy way. The 'detox' uses the idea that your body is full of toxins when in fact your organs are responsible for eliminating extraneous substances. If you go on any deprivation diet, you will probably lose a little weight, just because you are restricting calories. It is very likely you will regain this weight. ...Read more
How does one undertake kidney dialysis done; is it very uncomfortable and do you feel better after a treatment?
Peritoneal or hemo: There are 2 types of dialysis: hemodialysis & peritoneal. Hemodialysis is generally done at a dialysis center 3x/week & requires "access" into the blood stream, a fistula is preferred, it can also be done thru a large catheter (tube) that is placed in a neck vein. After dialysis, one may feel a bit drained. Peritoneal dialysis is done at home through a catheter inserted into the abdominal cavity. ...Read more
Mechanism: CPAP is considered the most effective treatment of OSA. Its beneficial effects are related to the normalization of breathing during sleep and to the prevention of nocturnal desaturations. Upper airway patency is maintained with NCPAP by a pneumatic splinting effect while changes in lung volume and pre-apnea SaO2 level may be implicated in the improvement of apnea-related desaturations. ...Read moreSee 1 more doctor answer
Usually One: The goal with defibrillator therapy is to minimize shocks. Most internal defibrillators are programmed with a high enough energy that they will often but not always be effective on the first shock. There are many variables to consider however and the data for external defibrillators (AED's) is different. ...Read moreSee 1 more doctor answer
How do pet scans work? My wife is scheduled for a pet scan and i was wondering how it works. Is this a good test relative to the other kinds of tests you can do? Is it accurate? Do you know how long it usually takes to get the results back?
Positrons -Really!!: A pet/ct looks at the function of the body. Radioactive drugs (usually a glucose analog) distribute based on differences in function, release a positron (antimatter), which is destroyed by combining with an electron, making an x-ray we detect. Follow the directions the imaging center gives exactly, because patient prep is critical to getting the best test. Pet/cts are usually read the same day. ...Read moreSee 2 more doctor answers
Weird protocol: For executions in the US. First, the barbiturate sodium pentothal for sleep. Then succinyl choline for paralysis. Then potassium chloride to stop the heart. The last is very painful if the person isn't asleep. Other drugs may be substituted, and the new one-drug protocol used just a barb. The complex protocol has been bungled. ...Read more

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. With mutated genes the corrections not made and mutation is passed to divided cells. There are enzymes like telomerase to allow the mutated cell to have immortality. ...Read more

Clarify, please!: A fumarole is a volcanic vent in the earth that releases hot water vapor. It is not the name of a medical treatment. There are a couple of drugs that have fumarate (a chemical compound) in them. Which do you mean? Ask again, and specify, please. ...Read more
How serious is kidney delation? How is it treated? Does it heal for good or life time pain? Does one with it be able to give birth to a healthy baby?
?U mean dilatatation: Not a good adjective but likely is referring to kidney being swollen with urine which is known as hydronephrosis. This is most commonly related to some degree of obstruction past or present. Needs 2b treated if due to kidney stone. Mild dilatation, without significant obstruction is usually benign ; requires no treatment. Severe obstruction usually needs surgery.Thus, there is spectrum of severity. ...Read moreSee 1 more doctor answer
