Abstract
An extracorporeal blood circulation system monitors blood level in a reservoir which temporarily stores the blood. A memory storage unit stores blood pressure measurements from a pressure sensor monitoring a blood pressure within a tube unit conveying blood from the reservoir relative to atmosphere. A processing unit that detects a height of a top surface of the blood stored in the reservoir based on changes in the blood pressure measurements and a conservation of mechanical energy of a blood flow inside the tube unit. A notification is generated if an abnormality is detected in the height of the blood in the reservoir.
