Passive Leg Raise Response Calculator

Assess fluid responsiveness using the passive leg raise (PLR) maneuver: a ≥10% increase in cardiac output or pulse pressure after leg elevation to 45° predicts volume responsiveness.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Assess fluid responsiveness using the passive leg raise (PLR) maneuver: a ≥10% increase in cardiac output or pulse pressure after leg elevation to 45° predicts volume responsiveness

Each component has a specific meaning:

  • Passive leg raise maneuver: a ≥10% increase in cardiac output or pulse pressure after leg elevation — The passive leg raise maneuver: a ≥10% increase in cardiac output or pulse pressure after leg elevation recorded for the scenario being assessed.

Note: Interpret the passive leg raise result against the thresholds and context described above.

How to Use

Enter the passive leg raise maneuver: a ≥10% increase in cardiac output or pulse pressure after leg elevation for the scenario you are assessing. Assess fluid responsiveness using the passive leg raise (PLR) maneuver: a ≥10% increase in cardiac output or pulse pressure after leg elevation to 45° predicts volume responsiveness. Use the passive leg raise result to inform your calculation.
