Multiple Organ Dysfunction Score (MODS)

Intensive-care severity index that grades dysfunction in six organ systems—respiratory, cardiovascular, renal, hepatic, hematologic, and neurologic

Clinical context

For reference calculations used alongside MODS components: • P/F ratio = PaO2 / FiO2 (FiO2 as a decimal) • Pressure-adjusted heart rate (PAR) = Heart rate × Central venous pressure / Mean arterial pressure Use measured hemodynamic values and interpret trends, not isolated points.
