The hollow fibers of a hemoconcentrator typically measure what micron size?

The correct choice regarding the typical size of the hollow fibers in a hemoconcentrator is associated with the range of 180 to 200 microns. Hemoconcentrators utilize hollow fiber technology to selectively filter blood components by size. The design of these fibers allows them to separate smaller molecules, such as water, electrolytes, and waste products, from larger components, such as red blood cells and plasma proteins.

The specified micron size range of 180 to 200 is optimal for achieving effective concentration of blood cells while minimizing the loss of essential components. This size ensures that the hemoconcentrator effectively retains the cellular elements of blood, which are crucial for maintaining patient stability during procedures such as cardiac surgery, all while removing excess fluid.

The other options fall outside this typical range and would not provide the same level of efficiency in filtering while retaining essential blood components. Therefore, understanding the correct choice helps in recognizing the design and function of hemoconcentrators in clinical practice.
