Step-by-step explanation:
The usual infusion time for Packed Red Blood Cells (PBRCs) is typically 2 to 4 hours. The actual duration can depend on the individual patient's condition and the specific protocols of the healthcare facility. In a general sense, transfusions should be administered slowly to monitor for any adverse reactions and ensure patient safety. The standard recommendation is to start with a slower rate and then increase to a maximum rate if the patient is tolerating it well, with close monitoring throughout the infusion.
