Adjusting gas flow during heart-lung machine rewarming
Part of Hormones & metabolism clinical trials.
This study tests how adjusting the amount of sweep gas (a gas mixture) during the rewarming phase of heart-lung machine use might affect patients. It's for people having planned heart surgery with a standard heart-lung machine, not minimally invasive or robotic surgery.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years old or older.
- You are having planned (elective) heart surgery that uses a heart-lung machine.
- Your surgery is not minimally invasive (small incisions) or robotic.
- Your body will not be cooled to very low temperatures (deep hypothermia) during surgery.
- Your blood circulation will not be completely stopped (total circulatory arrest) during surgery.
- You do not need a very high amount of oxygen in the breathing machine (FiO2) that would prevent adjusting the target gas flow.
