Gauge

From WikiMD's Wellness Encyclopedia

Gauge is a term used in various fields, including medicine, to denote a standard measure or scale of measurement. In the medical field, it is commonly used to refer to the size of a needle or catheter. The gauge of a needle refers to its diameter, with a higher gauge indicating a smaller diameter.

Medical Use[edit | edit source]

In medicine, the gauge of a needle or catheter is an important factor in determining its appropriate use. For example, a larger gauge (smaller diameter) needle may be used for more delicate procedures, while a smaller gauge (larger diameter) needle may be used for procedures requiring a larger volume of fluid to be administered or withdrawn.

Measurement[edit | edit source]

The gauge of a needle or catheter is typically measured in millimeters (mm). However, the gauge number does not directly correspond to the diameter in millimeters. Instead, it is based on a standard scale, with each gauge number representing a specific diameter. For example, a 20-gauge needle has a diameter of approximately 0.9 mm, while a 22-gauge needle has a diameter of approximately 0.7 mm.
