Why do you not always feel a needle?
The gauge of the needle, what the needle is being used for (IV, tattoo, blood draw, injection, etc.) all have an impact on the sensation experienced when a needle penetrates the skin. With injections in particular, the solution's thickness will definitely contribute to it. The thicker the solution, the more painful.
What gauge needle is used for a tragus piercing?
Mine was done with a 16g needle (:
Is a 22 gauge smaller than a 23 gauge needle?
Gauge is the term that indicates the diameter of the needle. Most commonly the needles that are used for medical purposed range from 7 Gauge to 33 Gauge, according to the Stubs scale. 7 Gauge needle will have the largest diameter while as the number increase, the diameter decreases. Therefore the 33 Gauge needle has the smallest diameter. So a 26 Gauge needle will have a smaller diameter than that of the 18 Gauge needle.
Where gauge metal treades are used?
needle- is used for sewing.
What needle gauge is used on the typical patient for a chemistry profile?
Depends how it is drawn- Butterfly or straight stick 19 g and 21 G are the normal straight stick. If you use a buterfly to draw the lab then they are ususally 21 or 23 Gauge. (Remember the bigger the gauge number the smaller the needle width). The smaller the needle width the higher the chance of hemolization (cell squishing)

How big is the needle they used in blood donations?
Usually a large bore needle is used in emergent situations, such as an 18-gauge or 16-gauge. The old standard was to use a catheter no smaller than a 20-gauge. Research shows that a 22-gauge needles will suffice without significant hemolysis (blood cell rupture). Remember that the bigger the gauge number, the smaller the diameter.Miller MA, Schlueter AJ. Transfusions via hand-held syringes and small-gauge needles as risk factors for hyperkalemia. Transfusion 2004;44:373-381.Frelich R, Ellis MH.

What can happen if too small of a needle is used during a blood draw?
It makes drawing the blood much slower, and the extra pressure used to force blood along a narrow needle can damage some blood cells as well as causing the patient extra pain. A larger needle always hurts less than a tiny one because of the pressure principle. All true! Additionally, it's easy to clog a really small bore needle, sometimes before the sample is complete.
