Health

Convert serum/urine creatinine between mg/dL and µmol/L. Factor 88.4 (molar mass 113.12 g/mol). Derived from KDIGO 2012, Young 1987, StatPearls. Not medical advice.

Media

Turn a single vocal into a wide stereo harmony stack of 3, 5, or 7 transposed voices panned across the field.

Media

Create an artificial-double-tracking style doubled vocal with micro-delay, pitch drift, and stereo widening.

Health

Compute CI = CO / BSA with BSA from the Mosteller formula √(height × weight / 3600). Normal 2.5–4.0 L/min/m². Derived from Mosteller NEJM 1987, Du Bois 1916, StatPearls, LITFL. Not medical advice.

Health

Compute CO = VO₂ / (CaO₂ − CvO₂) / 10 (L/min) with the Fick principle. Requires PA-catheter mixed venous samples. VO₂ defaults to 250 mL/min. Derived from Fick 1870, StatPearls, LITFL, West, Leach 2002. Not medical advice.

Health

Convert cholesterol and triglycerides between mg/dL and mmol/L. Factor depends on analyte: cholesterol 0.02586, triglycerides 0.01129. Derived from NCEP ATP III, ESC/EAS 2019, Young 1987, StatPearls. Not medical advice.

Health

Calculate PAO₂ = FiO₂ × (P_atm − 47) − PaCO₂ / RQ. Defaults: P_atm 760 mmHg (sea level), RQ 0.8. Gives a directional hint vs expected ~100 mmHg. For full A-a gradient interpretation use a-a-gradient-calculator. Derived from StatPearls, LITFL, Cornell PICU, and West. Not medical advice.

Health

Calculate VA = (VT − VD) × RR in L/min. VD may be supplied or estimated as ~2 mL/kg body weight. Normal resting ~4–6 L/min; low → hypercapnia, high → hypocapnia. Derived from West, LITFL, StatPearls, and Radford 1955. Not medical advice.

Health

Solve any one of pH/HCO₃⁻/PaCO₂ from the other two via pH = 6.1 + log10(HCO₃⁻/(0.03×PaCO₂)). Reports linear Henderson [H⁺] cross-check. Derived from Henderson 1908, Hasselbalch 1916, Siggaard-Andersen 1974, LITFL, StatPearls, Berend 2016. Not medical advice.

Health

Calculate base excess (BE) using the Siggaard-Andersen formula. BE < −3 metabolic acidosis, > +3 metabolic alkalosis. HCO₃⁻ auto-calculated from pH + PaCO₂ if omitted. Derived from Siggaard-Andersen 1974, Cornell PICU, Medscape, and Langer 2022. Not medical advice.

Health

Complete ABG analysis: pH, primary disorder, compensation (Winter's formula), anion gap ± albumin correction, delta ratio for mixed disorder detection. Derived from Emmett 2016, Kraut 2007, Rastegar 2007, LITFL, MDCalc, and Adrogué 1998. Not medical advice.
