Testing fluid response during heart bypass surgery
Part of Heart & circulation, Lungs & breathing clinical trials.
This study tests a method to see if your body needs more fluids during heart bypass surgery. After the surgeon opens your chest, they will use a special breathing maneuver to check how well your heart responds to extra fluid, which may help guide your care.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 80 years old.
- You are scheduled for elective coronary artery bypass surgery (not an emergency).
- Your overall health status is ASA class 2 or 3 (generally healthy or with mild to moderate systemic disease).
- Your heart's pumping ability is 40% or higher (ejection fraction ≥ 40%).
- Your body mass index (BMI) is 30 or less.
- You do not have chronic lung disease (COPD, bullous lung disease) or moderate to severe pulmonary hypertension.
