    The review discusses mean circulatory filling pressure and mean systemic filling pressure's roles in blood return to the heart.

  • 2

    Mean systemic filling pressure drives blood back to the right atrium, influencing venous return and cardiac output.

  • 3

    The pressure gradient between mean systemic filling pressure and right atrial pressure is typically small, around 3 to 6 mmHg.

  • 4

    Right atrial pressure above 8 to 10 mmHg may indicate caution with fluid administration to prevent venous congestion.

  • 5

    The authors conclude that mean systemic filling pressure's relationship with right atrial pressure is crucial for clinical interpretation.
