Abstract
A container of a dialysis machine has a determined shape and a known volume occupied in part by a volume of a mass of blood; a remaining part is occupied by a volume of a mass of gas. A disturbance is induced in a combined mass of the liquid and the gas in the container and an entity of the disturbance is measured. Measurements of pressure in the container before and after the disturbance are taken, the volume of gas is calculated using a function correlated to a gas law, and the volume and level of the liquid in the container are derived after the volume occupied by the gas is calculated.
