Could a simple breathing trick stabilize blood pressure during dialysis?
NCT ID NCT07773311
First seen Aug 19, 2026 · Last updated Aug 20, 2026 · Updated 1 time
Summary
This trial tests whether a specific breathing exercise, done during hemodialysis sessions, can reduce the occurrence of intradialytic hypotension—a sudden drop in blood pressure that can cause dizziness, nausea, and cramps. Sixty-six adults on regular dialysis are randomly assigned to either perform the breathing exercise during 12 sessions over four weeks or receive routine care. Researchers monitor blood pressure changes and track how often hypotension occurs, aiming to see if this simple, drug-free intervention can improve hemodynamic stability.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- A guided breathing exercise performed during hemodialysis sessions
- What this could lead to
- If effective, this drug-free technique could offer a simple, low-cost way to reduce dangerous blood pressure drops during dialysis, improving patient safety and comfort.
- What could go wrong
- This is a small, early-stage trial, and results may not apply to all dialysis patients. The exercise may be difficult for some to perform, and its benefits remain unproven until data are analyzed.
