Volume

Volume

Volume is the amount of three-dimensional space that a substance (such as solid, liquid or gas) occupies, or the space enclosing the substance, or the capacity of the container for the substance.

Signal Overview

Volume can be expressed as cubic metres or in litres, depending on the nature of the substance. Liquid and gas volume changes with time correlating to specific events are often studied in physiology.

In cardiovascular physiology, ventricular systolic and diastolic volumes are often measured, which can be used to derived further measurements, such as stroke volume (SV), and left ventricular end diastolic volume (LVEDV). The blood volume is often an important measurement in circulation studies, while lung volume measurements provide vital information in respiratory studies. Other studies may involve the volumes of secretions or volumes being filtered. Additionally, in drug studies, volumes of solutions and drugs are also necessary for calculating and introducing accurate and precise doses.

There are many methods to measure volume, either directly using graduated markings of measuring cylinders, beakers, other glassware and syringes, or indirectly using impedance/conductance methods with ionic solutions, volume flow measurements, optical methods and measuring changes of spatial markers.

Precise valid blood resistivity readings

Experiencing wildly different volume values because of fluctuating blood resistivity measurements during volume conversion?

Precise valid blood resistivity readings require the Rho cuvette to be at the set constant temperature just before measurement. Note that the temperature may sharply decrease depending on the room temperature, once the Rho Cuvette is removed from its warming source (i.e. a heated water bath). Therefore, the Rho Cuvette can be heated several degrees higher than the set temperature, allowing sufficient time for the transfer of the blood sample.
