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.
Tungsten has the highest melting point of all metals and, at temperatures greater than 1650Â°C, the highest tensile strength. Its thermal expansion rate is similar to that of borosilicate glass and silicon. Tungstenâs good thermal and electrical conductivity make it an excellent choice for microprocessor applications.
