Using light sensors to monitor blood flow during heart surgery

This study is testing a new, non-invasive way to measure hemoglobin (the part of blood that carries oxygen) using a light sensor on the skin, without needing extra blood draws. The goal is to see if this sensor is accurate for children having heart procedures, which could reduce the number of needle sticks they need.

This trial checks how well pulse oximeters (devices that measure oxygen levels) work in children with congenital heart disease who have different skin colors. It aims to make sure these devices are accurate for all children during heart surgery.

This study uses a non-invasive light-based technique to monitor oxygen levels in the heart muscle during open-heart surgery in children. It aims to see if this method can help doctors better manage the surgery and improve outcomes.

This study looks at whether simple monitoring tools (like a pulse oximeter and a device on the forehead) can help doctors spot early signs that a child's heart is not pumping well after surgery for a congenital heart condition. The goal is to help doctors intervene sooner to prevent complications.

This study uses a special light-based device to measure oxygen levels in your tissues during vascular surgery. It aims to see if this monitoring can help doctors better understand blood flow during the operation, which may help improve outcomes.

This study checks whether a new non-invasive measurement of oxygen delivery is accurate in patients having heart surgery. Participating may help improve monitoring during and after surgery, without extra procedures beyond what is already part of your care.
