Estimated Plasma Volume Status (ePVS)
Estimated plasma volume status (Duarte 2015): 100 × (1 − hematocrit fraction) / hemoglobin; a higher value marks more congestion in heart failure.

Example
- Hematocrit
- 40 %
- Hemoglobin
- 13 g/dL
Result: Estimated plasma volume status 4.62 dL/g — within the usual range.
The tool opens with these values already filled in. Replace them with your own.
What the result means
- Estimate
- ePVS = 100 x (1 - hematocrit fraction) / hemoglobin; higher values suggest plasma-volume expansion / congestion. An estimate, not a diuretic order.
