| This matrix-type patch system transports OXY directly into the systemic circulation across intact skin. |
| In right heart failure, ventricular dysfunction slows blood flow in the systemic circulation. |
| Thus only minute traces of radioactivity pass into the systemic circulation. |
| The left heart pumps oxygenated blood out to the systemic circulation. |
| After synthesis in the bone marrow, they migrate to the systemic circulation and on to the lung. |
| Even a minute difference between the outputs, if sustained, would very rapidly empty either the pulmonary or the systemic circulation. |
