Research aims to reduce strokes caused by tiny air bubbles entering the blood stream during heart surgery

Dr Ben Gibbison and his team from the Bristol Heart Institute and the Bristol Trials Centre are investigating how to reduce strokes and other brain problems following heart surgery, which can be caused by tiny air bubbles left in the bloodstream after opening the heart. These tiny air bubbles stop blood getting to part of the brain.

The study, which started in October 2021 and is currently recruiting, is called the CO2 Study. It is funded by the National Institute for Health Research (NIHR) and sponsored by University Hospitals Bristol and Weston NHS Foundation Trust (UHBW).
