My blood pressure is still pretty volatile, like a risky stock price. I took the exact same medication as I did last Saturday: one NIFEdipine ER the night before and skipping the other two medications in the morning. I probably weighed about a kilogram more so maybe there’s more fluid in the bloodstream. Here’s what I recorded from the dialysis machine:
| Time | Systolic | Diastolic | BPM | Notes |
| 5:34 am | 138 | 71 | 61 | |
| 5:40 am | 138 | 69 | 59 | |
| 6:12 am | 144 | 78 | 61 | |
| 6:41 am | 141 | 74 | 61 | |
| 7:11 am | 158 | 79 | 60 | |
| 7:42 am | 148 | 83 | 65 | |
| 8:11 am | 149 | 85 | 65 | |
| 8:41 am | 129 | 80 | 67 | |
| 9:11 am | 160 | 90 | 64 | |
| 9:45 am | 125 | 77 | 69 | standing |
The readings appear to be 10-15 points higher (systolic) versus Saturday. The head nephrologist was rounding today and he looked at my readings but had no comments. I think the numbers are still high but everyone else at the clinic seems to be fine with the results.
The blood pressure readings also vary a lot depending on how I am sitting. Usually the last reading is taken while standing since your blood pressure drops when you stand. If it’s <100, then they won’t let you leave, especially if you drive. There was a huge 35 point drop from the 9:11 am reading. Your blood pressure is also higher if you are reclined or lying down. I forgot to record how I was sitting at each of the readings so that could account for some of the variability.
