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

Calculate damping coefficient and natural frequency from fast-flush test to determine if arterial waveform is underdamped or overdamped

Each component has a specific meaning:

  • Fast-flush test — The fast-flush test recorded for the scenario being assessed.

Note: Interpret the arterial damping result against the thresholds and context described above.

How to Use

Enter the fast-flush test for the scenario you are assessing. Calculate damping coefficient and natural frequency from fast-flush test to determine if arterial waveform is underdamped or overdamped. Use the arterial damping result to inform your calculation.
