What this Trial Is About
Researchers are evaluating whether the Pleth Variability Index (PVI), a simple and non-invasive measurement from a pulse oximeter, can predict low blood pressure during routine maintenance hemodialysis. This is important because low blood pressure during dialysis is a common and potentially serious complication. The study focuses on adults aged 18 to 80 years who have been on maintenance hemodialysis for more than three months. All participants will have their PVI measured using a fingertip device before dialysis starts and again 30 minutes into the session. Blood pressure will be closely monitored throughout dialysis. No experimental treatments will be given, as this is an observational study. Researchers will collect data on participants' age, medical history, medications, lab results, and dialysis settings. During the study, participants will undergo PVI and blood pressure monitoring during a dialysis session lasting up to four hours. Researchers will analyze the predictive value of PVI and its changes for intradialytic hypotension. Participation is voluntary, with no extra risks beyond routine care. The study aims to improve safety during dialysis by identifying patients at risk for low blood pressure.
