The correct answer is: D. Blood flow in heart lung machine
A Venturi is a device that uses the principle of fluid dynamics to create a pressure difference between two areas. This pressure difference can be used to create a vacuum, to accelerate a fluid, or to measure the flow of a fluid.
In a heart lung machine, a Venturi is used to create a vacuum that draws blood from the patient’s body. The blood is then oxygenated and returned to the patient’s body.
Venous blood pressure is the pressure of blood in the veins. It is lower than arterial blood pressure.
Digital plethysmography is a technique used to measure blood flow in a finger or toe. It is used to diagnose peripheral artery disease.
Dialysate flow in an artificial kidney is the flow of fluid that is used to remove waste products from the blood.
