Patient care is another part of the job. Patient care involves you directly interacting with those receiving their dialysis treatments. In any type of medical treatments, problems can and do arise from time to time. The dialysis technician records the patients physical and mental condition regularly to determine if a problem is about to occur. You will also monitor and record vital signs to determine if they are in the patients normal range. In dialysis, the patients blood is filtered in the machine. When the dialysis equipment is finished cleaning the blood of impurities it is returned to normal circulation. Special attention has to be paid to the amounts of toxic substances being removed from the blood during dialysis. Removing too much or too little of the unwanted components found in the blood can cause serious problems and may be life threatening for the dialysis patient.
