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

Calculates the 4-factor prothrombin complex concentrate (4F-PCC) dose for urgent warfarin reversal based on INR and body weight. High-intensity anticoagulation with life-threatening bleeding requires 50 units/kg IV

Each component has a specific meaning:

  • INR — The inr recorded for the scenario being assessed.
  • Body weight — The body weight recorded for the scenario being assessed.

Note: Interpret the warfarin pcc reversal result against the thresholds and context described above.

How to Use

Enter the INR, body weight for the scenario you are assessing. Calculates the 4-factor prothrombin complex concentrate (4F-PCC) dose for urgent warfarin reversal based on INR and body weight.
