Yup, another procedure this coming week. After a month of healing, they tried to use the vein for the last 3 weeks. Like, 2 to 3 attempts per treatment. They could feel they're in the vein, yet once they set the (dialysis) machine and walk away, it would stop working. The way it was explained to me, for whatever reason, the tip of the needle would stick to the wall and inhibit flow.
Meanwhile, on the work front -- this week I started training (hopefully) my successor so that I can retire. Unfortunately, he has zero experience or training in electronics. But he is smart and eager to learn. He graduated university in 2019 with a science degree but this is his first opportunity in industry/technology. In the end I conceded to the Boss because this job really has no formal educational requirement but there are courses and degrees out there. So I figure, we'll start on procedures so that he can feel productive.
