| For Protocol 4, animals were instrumented before delivery to measure pulmonary artery pressure and left atrial pressure. |
| At this time, the surgeon begins to develop a dissection plane between the aorta and the pulmonary artery. |
| Within the device, a diaphragm is actuated pneumatically, electrically, or magnetically, and it pumps blood into the aorta or pulmonary artery. |
| Blood then goes through the main pulmonary artery to the right and left pulmonary arteries, which lead blood to the lungs. |
| The pulmonary artery pressure during the initial 10 minutes of reperfusion is of prime importance. |
| The main defect is due to the narrowing and under-development of the pulmonary artery in the lungs, the site of purification of blood. |
