needle gauge

Needle gauge refers to the thickness or diameter of a needle, with a higher gauge number indicating a thinner needle. For example, a 25-gauge needle is thinner than a 21-gauge needle. The gauge affects the flow rate of fluids and the level of discomfort during injections, with thinner needles generally causing less pain. Healthcare professionals select the appropriate gauge based on the procedure, the type of fluid being injected, and the patient's needs. Understanding gauge helps ensure effective and comfortable injections while maintaining safety standards.
