What is the primary purpose of priming blood lines before dialysis?

The primary purpose of priming blood lines before dialysis is to remove air and reduce adverse reactions. When initiating dialysis, it is crucial to ensure that the blood lines are free of air bubbles. Air in the blood lines can lead to complications such as air embolism, which can be dangerous for the patient. By priming the blood lines with a sterile solution, typically saline, healthcare providers can flush out any air and ensure that the circuit is completely filled with fluid, allowing for uninterrupted blood flow during the dialysis process. This step is essential for maintaining patient safety and the effectiveness of the treatment, as it minimizes the risk of adverse reactions associated with air entering the bloodstream.
