Detection of inflow obstruction in left ventricular assist devices by accelerometer: An in vitro study
Medical Engineering & Physics(2022)
摘要
•An accelerometer detects inflow obstructions in left ventricular assist devices.•Inflow obstructions-related vibrations emerge before the pump flow reduces.•Accelerometer-captured vibrations may warn about inflow obstructions.•An accelerometer had better diagnostic accuracy than the pump power consumption.
