What is a critical step to prevent air embolism during IV therapy?

The critical step to prevent air embolism during IV therapy is to ensure all air is removed from the IV line. Air embolism can occur when air enters the vascular system, potentially causing serious complications such as obstruction of blood flow, ischemia, or even death. By ensuring that all air is expelled from the IV line before connecting it to a patient, healthcare providers significantly reduce the risk of air entering the bloodstream.

This step is essential during the setup of IV therapy. It's important to carefully prime the IV tubing and remove any trapped air bubbles by allowing the solution to flow through the tubing and carefully manipulating it to eliminate any air pockets. Proper training and technique in this area can help ensure patient safety and prevent adverse events related to air embolism.
