Fórmulas Clínicas

Clinical Formulas brings together in one place the calculators you use every day in your clinical practice, with live results and classification tables specifically adapted to Mexico.

Includes:

Rabito — Estimated weight for non-ambulatory or bedridden patients, using only a measuring tape (arm, abdominal, and calf circumference). Ideal when the patient cannot be weighed on a scale.

BMI (Body Mass Index) — Automatic calculation with classification that adjusts itself according to age:
- Children and adolescents (2-19 years): official WHO/IMSS table, specific for age and sex
- Adults (20-59 years): standard classification with the 3 degrees of obesity
- Older adults (60+): IMSS table (GPC-095-24), because the normal range changes with age. Includes suggested normal weight and the number of kilograms of difference from the healthy range.

PC — Estimated weight in cerebral palsy — Formula validated specifically for children and adolescents with cerebral palsy (2–19 years), using arm circumference, age, and GMFCS level. Source: Ruiz Brunner et al., 2021.

Glomerular Filtration Rate (GFR) — Kidney function in adults, using the CKD-EPI 2021 equation (the same one used by the Mexican National Medical Care Protocol), classified by KDIGO stages.

Why it's different:
✓ Live results as you type, no "calculate" button
✓ Mexican tables verified against official IMSS guidelines and federal government documents
✓ Automatic age classification — the same table doesn't apply to a young adult as to a senior citizen
✓ Designed for quick use at work, on your phone

Important: All results are estimates based on published and validated formulas, intended as a support tool — they do not replace clinical judgment or diagnosis by a healthcare professional.

Made by and for nursing and healthcare professionals in Mexico.
