Understanding the Difference Between Large-Bore and Small-Bore Medical Tubing

Large-bore refers to the diameter of a tube or pipe, which is typically greater than 1 inch (25.4 mm). In medical contexts, large-bore tubing is often used for IV lines, oxygen therapy, and other medical applications where a larger inner diameter is required to facilitate the flow of fluids or gases.

In contrast, small-bore tubing has an inner diameter of less than 1 inch (25.4 mm) and is typically used for smaller medical applications such as peripheral IV lines, arterial lines, and central venous catheters.

It's worth noting that the exact definition of large-bore and small-bore can vary depending on the context and industry, but in general, large-bore tubing is larger in diameter than small-bore tubing.
