What is the result of using small bore suction tips during blood aspiration?

1. Enhanced fluid flow

2. Potential hemolysis

3. Increased suction pressure

4. Improved safety

The correct answer is: Potential hemolysis

Using small bore suction tips during blood aspiration can lead to potential hemolysis due to the increased shear stress that occurs as blood passes through a narrower diameter. When blood vessels are suctioned, the sudden pressure changes and the constriction of the small bore tip can damage red blood cells. This damage may lead to the release of hemoglobin and other intracellular components into the plasma, resulting in hemolysis. In contrast, larger bore suction tips can allow for a smoother flow of fluids and reduce mechanical trauma to the blood cells, thus minimizing the risk of hemolysis. Moreover, the design of suction tips is crucial in health care environments, as optimizing flow and minimizing cell damage are paramount when aspirations of blood or other tissues are performed.
