Blood Pressure During Dialysis

The dialysis machine measures your blood pressure every 30 minutes. Since your blood pressure typically drops during dialysis, they want to make sure it does not drop too low and cause you to black out. However, my blood pressure was going up instead. This is with taking the 25 mg of Metoprolol this morning.

First, if your legs/feet are raised, you would expect the blood pressure to be a bit higher. Initially, the numbers were in the 150’s. Still high, but should drop to 130’s when I stand. At some point, I put my feet up and you would expect a slight rise in blood pressure. However, I’m not sure what happened for the next two readings. I didn’t move that much but the blood pressure reading increased. Is something clogging? Why would blood pressure vary that much and go up? Maybe the 25 mg of Metoprolol I took this morning wore off. I believe the numbers kept climbing and only leveled off a bit currently since I took an extra 12.5 mg of Metoprolol.
