Venous access refers to the process of gaining entry into a vein to administer medications, fluids, or draw blood. This is commonly achieved using a needle or a catheter, which can be inserted into peripheral veins, such as those in the arms or hands, or central veins located deeper in the body. Proper venous access is crucial in medical settings, as it allows healthcare providers to deliver treatments efficiently. Techniques for venous access include venipuncture for blood draws and the placement of IV lines for continuous medication administration. Ensuring sterility and patient comfort is essential during these procedures.
