Passive Leg Raise Stroke-Volume Response
Passive leg raise response: percent change in stroke volume (or surrogate) from baseline to peak; a >= 10-15% rise predicts fluid responsiveness without giving fluid.

Example
- Baseline stroke volume / surrogate
- 60
- Peak value after leg raise
- 72
Result: Passive leg raise +20% stroke volume (60 -> 72): >= 10-15% -- predicts fluid responsiveness.
The tool opens with these values already filled in. Replace them with your own.
What the result means
- Threshold
- a rise of at least 10-15% predicts fluid responsiveness regardless of rhythm or ventilation mode.
What you enter
- Baseline stroke volume / surrogate
- Peak value after leg raise
How this is calculated
- Formula
- %dSV = (peak - baseline) / baseline x 100; measure the real-time stroke-volume surrogate within about one minute.
