Table 1

General considerations for intensive care management of patients in acute circulatory collapse. MCS: mechanical circulatory support; RV: right ventricle; LV: left ventricle; CRRT: continuous renal replacement therapy; ARDS: acute respiratory distress syndrome; CO: cardiac output

Hemodynamic assessment
  • Hemodynamic assessment with Swan-Ganz catheter is at the core of cardiogenic shock management.

  • A Swan-Ganz catheter should be used, particularly if MCS is considered.

  • A central line can assess volume status and mixed venous oxygen saturation.

  • Echocardiography is essential for assessing RV/LV function, CO, and filling pressures.

Fluid management
  • Avoid hyper- or hypovolemia.

  • In ARDS, hypervolemia may worsen respiratory status.

  • In hyperinflammation with severe cytokine response, functional hypovolemia due to capillary leak and intravascular volume depletion may lead to poor organ perfusion.

  • CRRT may be required to optimize fluid status.

Blood pressure maintenance
  • Maintain perfusion with vasopressors.

  • Norepinephrine is considered first line.

  • Vasopressin is considered second line.

Adequate cardiac output maintenance
  • Dobutamine or milrinone may be used to maintain CO.

  • When inotropes fail, early escalation to MCS may be considered as outlined.
