Final answer:
The most common site for CVP insertion is the subclavian vein due to lower risk of infection and complications. It allows for measurement of central venous pressure.
Step-by-step explanation:
The most common site for CVP (central venous pressure) insertion is the subclavian vein. This site is preferred due to lower risk of infection and complications compared to other sites such as the internal jugular vein or femoral vein.
Subclavian vein CVP insertion is performed by first locating the vein below the clavicle bone. The clinician then inserts a catheter into the vein, which is guided into the superior vena cava, allowing for measurement of central venous pressure.
It's important to note that the choice of insertion site may vary depending on the patient's condition and the clinician's preference, but subclavian veins are commonly used for CVP insertion.
