Cardiac arrhythmias and air embolism are recognized potential systemic complications associated with central venous access. When a central venous catheter is inserted, especially if it is not properly placed or if certain precautions are not taken, it can lead to serious effects on the cardiovascular system.

For instance, cardiac arrhythmias can occur if the catheter tip is positioned too close to the heart or irritates the cardiac tissue, potentially disrupting normal electrical conduction. Air embolism can happen if air enters the vascular system during the insertion or removal of a central line; this can obstruct blood flow and lead to significant complications such as stroke or cardiac arrest.

In contrast, other options like localized swelling and redness are more localized reactions and do not describe systemic complications. Infection and phlebitis, while serious, are likewise more commonly associated with local effects, despite having the potential to lead to systemic issues if not managed properly. Nausea and vomiting are non-specific symptoms that may arise from various causes and are not directly linked to the complications of central venous access. This understanding of the systemic complications helps in recognizing the critical nature of proper procedure and monitoring in vascular access.
