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

Model IHD session duration to achieve target Kt/V from blood flow, dialyzer clearance, volume of distribution of urea, and patient weight

Each component has a specific meaning:

  • Blood flow — The blood flow recorded for the scenario being assessed.
  • Dialyzer clearance — The dialyzer clearance recorded for the scenario being assessed.
  • Volume of distribution of urea — The volume of distribution of urea recorded for the scenario being assessed.
  • Patient weight — The patient weight recorded for the scenario being assessed.

Note: Interpret the ihd session length result against the thresholds and context described above.

How to Use

Enter the blood flow, dialyzer clearance, volume of distribution of urea, patient weight for the scenario you are assessing. Model IHD session duration to achieve target Kt/V from blood flow, dialyzer clearance, volume of distribution of urea, and patient weight. Use the ihd session length result to inform your calculation.
