As a medical professional with expertise in intravenous (IV) therapy, I can provide you with the correct procedure for inserting an IV.

When inserting an IV, the angle at which the needle is inserted can vary depending on the vein's location and the type of IV catheter being used. Generally, for a peripheral IV, the angle is typically around 15 to 30 degrees. This is because peripheral veins are more superficial and inserting the needle at a steeper angle could cause the needle to go through the vein. For a central line, the angle can be different and is determined by the specific site of insertion, such as the jugular, subclavian, or femoral vein.

It's important to note that the angle of insertion should be adjusted based on the patient's anatomy, the condition of the vein, and the type of IV catheter. The healthcare provider should always follow the manufacturer's guidelines and use their best clinical judgment.

Figure 1 shows the proper initial insertion angle for short peripheral IV catheters such as Secure IV?. Insert the catheter into the vein at a 15 to 30 angle. A large initial insertion angle can cause problems. Figure 2 shows an improper initial insertion angle (greater than 30��).read more >>
