Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - Nitric Oxide

Active comparator: Intervention arm - • Intervention arm will receive nitric oxide 20 parts per million (ppm) into the oxygenator of a cardio-pulmonary bypass circuit

No intervention: Control arm - Control arm will not receive nitric oxide, they will receive standard bypass as per local policy


Treatment: Drugs: Nitric Oxide
Addition of nitric oxide 20ppm into bypass circuit
