The PCT will then program the dialysis machine to the patientâs settings, assess and prepare the vascular access and connect the dialysis tubing to the access. The PCT will also look at the access to make sure it is in good working order. A dialysis treatment can take several hours. The PCT will monitor the patient and check vital signs every half hour as well as monitor the dialysis machine for the entire treatment time. After the patient is done dialyzing, the PCT will take the patient off the machine and weigh them again.
Most brass will melt at temperatures as low as 1,650ÂºF (900ÂºC), but a higher maximum temperature will give you a margin of error, and make the brass easier to pour.
1 If the zinc content of the brass ranges from 32% to 39%, it will have increased hot-working abilities but the cold-working will be limited.  If the brass contains over 39% zinc (example â Muntz Metal), it will have a higher strength and lower ductility (at room temperature).
