Could a breath of CO2 save Stroke-Damaged brain tissue?
Disease control Recruiting nowThis study tests whether raising carbon dioxide levels slightly during general anesthesia can improve blood flow to the brain before clot removal in stroke patients. Fifty adults with large-vessel stroke will be randomly assigned to either normal or moderately high carbon dioxide…

Pacing the heart to peek at brain blood flow
Knowledge-focused Recruiting nowThis study looks at how changing heart rate affects blood flow in the brain. Researchers will temporarily pace the hearts of 20 adults already scheduled for a heart procedure, then measure brain blood flow using ultrasound. The goal is to better understand the link between heart …

Brain blood flow study aims to uncover clues about aging
Knowledge-focused Recruiting nowThis study looks at how brain blood flow changes when healthy adults aged 55-69 breathe differently or shift posture, using MRI scans. Participants will also receive a single dose of prazosin or a placebo to see how it affects blood flow. The goal is to better understand the brai…

Oxygen overload? study probes brain impact in ventilated patients
Knowledge-focused Recruiting nowThis study looks at how short periods of high oxygen affect blood flow in the brains of ICU patients on breathing machines. Researchers will briefly increase the oxygen given through the ventilator and use ultrasound to monitor brain artery blood flow. The goal is to understand t…

Brain blood flow secrets revealed? new trial tests how we react to low flow
Knowledge-focused Recruiting nowThis study looks at how the brain's blood vessels respond when blood flow drops suddenly. Healthy adults aged 20-40 will undergo MRI scans while doing breathing exercises and a simulated postural change. Some will receive a single dose of prazosin, a blood pressure drug, to see h…
