I enjoy working at fresenius. The co worker were great. helped when needed. Managment was always there when we need them. In the morning, I would arrive at work, string my machines, test them, and then once they were all ready , and it was six am, we would bring the patients back. one tech would generally have four patients. We would access them, vital signs, calculate them, hook them to the machine. Once the patient was on the machine, we would take vitals from them every thirty minutes, and we would document vitals, and any changes.
