Multiple Organ Dysfunction Score (MODS)
Multiple Organ Dysfunction Score (Marshall 1995): six organ systems graded 0-4 from P/F ratio, creatinine, bilirubin, pressure-adjusted heart rate (HR x CVP / MAP), platelets, and GCS.

Example
- PaO2 / FiO2 ratio
- 350
- Serum creatinine
- 1.0 mg/dL
- Total bilirubin
- 1.0 mg/dL
- Pressure-adjusted heart rate
- 8
- Platelets
- 200 x10^9/L
- Glasgow Coma Scale
- 15
Result: MODS 0 of 24: ICU mortality 0% per Marshall 1995 Table 4.
The tool opens with these values already filled in. Replace them with your own.
