What is the size of cannula and when use it?
Different sizes of IV cannulas are colour coded to define the size and their usage. The IV cannula size generally varies from 14 to 24 gauge. The size is decided on the basis of the patient’s condition, purpose of the IV cannula and the urgency at which the fluid needs to be delivered.
What is 20G cannula?
BD Venflon I.V. Canulla 20G is developed to help minimise the risk of unanticipated blood splash and needlestick injuries. Key benefits: Robust needle tip protection-fully encapsulates needle tip.
What color is a 18 gauge needle?
Luckily, most manufacturers color code their IV needles. Here’s a little rhyme you can use to help you remember what colors correspond to what sized gauge: 22 is blue and 18 is green. Pink is the one in the middle. There are other IV gauge sizes besides those, although they aren’t as common.
What’s the biggest cannula?
Present day IV cannulae are available from sizes 14 gauge to 26 gauge with universal color coding for easy recongnition of IV cannula. Smaller the gauge, wider is the cannula and has higher flow rate.
What gauge is a yellow cannula?
24G

How do I know what size my cannula is?
Smaller the gauge, wider is the cannula and has higher flow rate.
- Normal adult size: 18-20 G.
- Situations requiring rapid fluid transfusion like trauma: 14-16 G.
- Preferred pediatric size: 22 G.
- Infants and neonates: 24-26 G.
What is the flow rate of 20G IV cannula?

| Color | Gauge Size | Water Flow Rate (mL/min)* |
|---|---|---|
| Pink | 20G | ~60 mL/min |
| Blue | 22G | ~36 mL/min |
| Yellow | 24G | ~20 mL/min |
| Purple | 26G | ~13 mL/min |
How do I know what gauge my IV is?
One of the of the important things to know when starting an IV is the proper needle size to use. IV needles are sized by gauges, and the smaller the gauge number, the bigger the needle will be.
What is an 18G needle used for?
18 Gauge: This size allows you to do most tasks that the 16 gauge can. Some of the common uses include administering blood, pushing fluids rapidly, etc. You can use this for CT PE Protocols or other testing that requires large IV sizes.
What size of cannula do I need for my patient?
Cannula sizes mainly range from 14 to 24 gauge. The purpose, the condition of the patient, and the urgency at which intravenous fluid must be delivered determine which cannula sizes must be used. The smaller the gauge, the larger the diameter of the cannula and the faster the flow of fluid
What is an intravenous cannula used for?
An intravenous cannula is a flexible tube that can be inserted into a patient’s body through the veins and is mostly used for administering medications and I.V. fluids as well as for taking blood samples. The sizes of intravenous cannula have different colour codes for different purposes. Cannula sizes mainly range from 14 to 24 gauge.
Which type of cannula is best for large vein catheterization?
An over the needle FEP large-bore cannula inserted into a large vein is likely to give a greater flow rate than a Seldinger type polyurethane catheter and would be preferable if all other factors are equal
What is the difference between Central line and peripheral cannula?
a peripheral cannula of size 18G or greater is preferable to infusion by central line for rapid fluid delivery if a central line is the only obtainable access then the addition of a pressure bag makes a greater difference to rate of flow than it would with a peripheral cannula
