Gamma calculation
Gamma (γ) = µg/kg/min. Enter the weight, the syringe concentration and the pump rate to read off the gamma. Works for any infusion — in practice most often noradrenaline. Adults.

Reference — noradrenaline is usually titrated around 0.01–0.5 µg/kg/min (higher in refractory shock). Gamma itself is drug-independent.
