Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Blood pressure and pulse wave velocity are measured using a blood pressure cuff. Blood pressure will be measured at the start of a dialysis session, then at 20 minutes, one hour and then hourly during the dialysis session. Changes in pulse wave velocity and heartbeat variation will be reviewed to determine whether these are related to changes in blood pressure during the dialysis session. | — |
Secondary
| Measure | Time frame |
|---|---|
| Derived variables from pulse wave velocity. | — |
