Quantitative anesthesia

Abstract

Quantitative anesthesia is delivering anesthetic and oxygen in known quantities, the dosage based on calculations for their uptake. The uptake is not linearly related to body weight but is linearly related to body weight raised to a power. The dosage of inhaled anesthetics is calculated by the method of Lowe. The oxygen consumption and cardiac output are estimated by formulas that relate physiologic functions to the body weight in kilograms, raised to a power.
