How long may blood processed by an autotransfusion device be stored at room temperature prior to transfusion, according to AABB guidelines?

2 hours
4 hours
6 hours
12 hours

The correct answer is: 4 hours

The correct duration for storing blood processed by an autotransfusion device at room temperature before transfusion, as per AABB guidelines, is 4 hours. This timeframe is crucial to ensure the safety and efficacy of the blood products being administered to patients. After processing, blood cells are more susceptible to bacterial contamination, which increases the risk of complications if the blood is stored beyond the recommended limit. The 4-hour guideline is established to provide a balance between allowing time for the blood to be handled and infused safely while minimizing the risk of any adverse reactions. Following these guidelines is essential for maintaining the integrity of the blood product and ensuring patient safety during transfusion procedures.
