Why Do Some People Pass Out While On A Dialysis Machine
Low Blood Pressure: Unfortunately, dialysis is an exchange of blood between the patient and the hemodialysis machine. At certain times, too much blood can be taken from a patient that leads to an acute drop in blood pressure. This decrease in blood pressure likely leads to some people passing out while on the hemo-dilaysis machine. ...Read moreSee 1 more doctor answer
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
Filter, toxins: Dialysis does the work of kidney- removing fluids andtoxins. Blood from the patient flows on one side of the chamber and the dialysate solution which contains the optimal concentration of electrolytes on other side of the chamber. Electrolytes move along the concentration gradient, so toxins which are high in the blood, goes to the dialysate solution. ...Read more
Countercurrent flow: The dialysis machine is based on pumps that move blood through the artificial kidney (a filter) while making dialysate (a mixture of water and chemicals) to move the opposite direction through that filter. The blood and dialysate are separated by a semipermeable membrane in the filter. By moving in opposite directions, the waste products in the blood tend to go into the dialysate cleaning the body. ...Read more
Dialysis: I am presuming you are asking about hemodialysis. If you have a shunt created under your skin (arteriovenous shunt), you will be connected using needles. If you have an external, plastic shunt you will be connected without needles. Either way, connecting a patient to a dialysis machine requires great care and major attention to preventing infection. ...Read moreSee 1 more doctor answer
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
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

Flow rate?: Blood may clot in the dialysis circuit if it isn't flowing fast enough. Blood has a tendency to clot if it 'stands still' or slows down enough. The quality of the 'access' ( i.e., usually a fistula) may be a factor here. Additionally, the position of the needles within the fistula may also impact the flow rate. And needless to say, a crimped line will result in clotting if not corrected. Lgromkomd. ...Read moreSee 1 more doctor answer
Kidney machine clog?: I am not sure what you are referring to by a dialysis patient's clogging of a kidney machine. Patients can have their dialyzer (d), the artificial kidney, during dialysis. This normally occurs when the patients are not getting enough Heparin during dialysis and their d's clot ending their use of that d. If that is not the answer you were looking for, ask the patient's nephrologist youyr question. ...Read more
