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

Predict fluid responsiveness from IVC collapsibility index in spontaneously breathing patients. >50% collapse predicts response

Each component has a specific meaning:

  • IVC collapsibility index in spontaneously breathing patients — The ivc collapsibility index in spontaneously breathing patients recorded for the scenario being assessed.

Note: Interpret the ivc fluid response result against the thresholds and context described above.

How to Use

Enter the IVC collapsibility index in spontaneously breathing patients for the scenario you are assessing. Predict fluid responsiveness from IVC collapsibility index in spontaneously breathing patients. >50% collapse predicts response. Use the ivc fluid response result to inform your calculation.
