What can lead to an air embolism during venipuncture?

An air embolism during venipuncture can occur when there is a breach in the venous system that allows air to enter the bloodstream. One critical factor contributing to this risk is the improper clearance of the line used for drawing blood or administering fluids. When a line is not adequately cleared of air before the procedure, it may inadvertently allow air bubbles to be infused into the bloodstream, thereby increasing the risk of an air embolism.

Properly purging the line of air ensures that only the intended fluid is delivered, minimizing the chances of air entering the circulation. This step is particularly crucial when using filters or other devices, as any trapped air can cause complications if not appropriately managed. Overall, maintaining meticulous technique during venipuncture and line management is vital to prevent such adverse events.
