What gauge needle is best to prevent hemolysis while transferring blood from a picc line to a lab tube?
hemolysis occurs due to the needle lumen being too small (ie a larger gauge). The larger the needle (or lower gauge), the less likely it will damage the cells and cause hemolysis. Avoid 25g and smaller needles.
What gauge needles are commonly used or blood draws?
Commonly used needle gauges for blood draws are 21-gauge and 22-gauge needles. The 21-gauge needle is often preferred for adults due to its balance between flow rate and comfort, while the 22-gauge is frequently used for pediatric patients or those with smaller veins. In some cases, a 23-gauge needle may be used for very small veins. The choice of gauge depends on the patient's age, vein size, and the volume of blood needed for testing.
How was the problem of different gauges solved?
Small railroad companies were into larger ones who then worked out a common gauge.

How do you adjust a small knitting pattern to a larger size?
One really easy way to do it is to use heavier yarn & bigger needles than what is called for in the pattern. For example: a ladies size small sweater knitted with DK or sportweight yarn with size 5-7 needles would be larger, size-wise, if knitted with worsted weight or bulky yarn on size 8-10 needles. You can use the same yarn & just knit with bigger needles, but this will result in a more loosely woven fabric & change the look of the piece significantly. If planning on making a pattern several sizes bigger, however, I would add stitches. This is easy to do in a patern where there is a significant amount of stockinette stitch used. However, it does tend to get a little more difficult if using pattern stitches. Remember to swatch, so you know your gauge, and if increasing a pattern repeat to make larger, be sure to cast on enough stitches.
Are smaller fractions larger?
the numbers are larger, but could mean less or more: 1/20000000 is small and 20000000/1 is large
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.

Can plastic surgery close the small holes of pierced ears?
I've only heard of reconstructive surgery for larger gauge ear piercings. Howver, you should look into getting your ears pierced at a larger gauge to remove the scar tissue. That way you could let them heal without the scar tissue stopping you.
How do you calculate the number of different sudoku puzzles?
In an average Sudoku puzzle there are nine larger boxes with nine small boxes inside each. The small boxes each get a number one through nine so that each larger box has nine different numbers in it. Therefore, nine different numbers are used and 81 numbers total.
What needle is used when drawing blood from the feet?
When drawing blood from the feet, healthcare professionals typically use a butterfly needle or a small-gauge needle, such as a 23-gauge or 25-gauge needle. Butterfly needles are preferred for their ease of use and maneuverability in smaller veins. It's essential to ensure proper technique and site selection to minimize discomfort and complications. Always follow institutional protocols for venipuncture.
Why would a 20 gauge Stevens shotgun not have any serial numbers on it?
Serial numbers on long guns were not required in the US until 1968, so many manufacturers did not assign them to shotguns and small-caliber rifles.
