1⛑️2 Not-Out: Tools

Description-

Calculator to compute blood flow rate (Qb) or dialysate flow rate (Qd) for hemodialysis treatments.

Dialysis Flow Rate Calculator

Compute blood flow rate (Qb) or dialysate flow (Qd) quickly — mobile-friendly and copy-ready.

Calculation type Blood Flow Rate (Qb) — from volume & time Dialysate Flow Rate (Qd) — from dialysate volume & time Estimate Qb from Kt and treatment time (approx.)

Clinical note: This calculator provides arithmetic estimations. For clinical decisions consult a nephrologist or dialysis protocol. Inputs assume volume in milliliters (mL) and time in minutes or hours as labelled.

2-Alkali Therapy Calculator

Estimate bicarbonate deficit and sodium bicarbonate replacement dose.

Patient Weight (kg) Actual HCO₃⁻ (mmol/L) Desired HCO₃⁻ (mmol/L, default 24)

Formula: Bicarbonate Deficit = 0.5 × Weight (kg) × (Desired HCO₃⁻ – Actual HCO₃⁻).
Typically, half of the calculated dose is given initially and reassessed. Always consult nephrology/critical care protocols before treatment.

3- Fractional Excretion of Magnesium (FEMg) 

 Information 

 The FEMg calculation is used to assess magnesium excretion and kidney function. It is useful in the diagnosis of hypomagnesemia or hypermagnesemia. This calculation helps in understanding whether the magnesium level abnormalities are due to renal losses. FEMg Calculation FEMg (%) = ((Urine Magnesium / Serum Magnesium) / (Urine Creatinine / Serum Creatinine)) × 100
