Summary

The pulmonary circulation differs significantly in characteristics from the systemic circulation. The pulmonary circulation is a low-pressure, low-resistance, high-flow circulation: a blood flow of 5 L/min (i.e. 100% of cardiac output, CO) is achieved with a driving pressure (i.e. mean pulmonary artery pressure, MPAP) of only 15 mmHg.
