A volume based measurement is carried out by objectively measuring the volume of body parts by using fluid displacement methodology. By placing the body or a particular body part in a water filled tank and allowing overflow, measurements are taken. By doing this, the edema amount, which is the swelling caused by excess fluid trapped in body’s tissues is measured. Volume and Edema measurement gauges are manufactured from industry leaders like Baseline, who provide services to a host of patients for biometric analytics or to diagnose certain conditions. Edema could diagnose various fatal complications such as cirrhosis, kidney damage and heart failure. Insights gained from volume and edema gauges can be useful for a range of diagnosis and patient care or full body wellness purposes.
