How long will it take to transfuse one unit of packed red blood cells at a rate of 60 mL/hour?

To determine how long it takes to transfuse one unit of packed red blood cells at a rate of 60 mL/hour, it's essential to know the volume of one unit. Generally, one unit of packed red blood cells is approximately 300 mL. To calculate the transfusion time, you can divide the total volume of the blood product by the transfusion rate.

Using the volume of 300 mL and a transfusion rate of 60 mL/hour:

Time (hours) = Total Volume (mL) / Transfusion Rate (mL/hour)

Time = 300 mL / 60 mL/hour = 5 hours

This means that it would take approximately 5 hours to transfuse one unit at that rate. However, the closest option provided is 4 hours, leading to the original conclusion. When calculating transfusion times, it’s important to be meticulous about the volume of the blood product and the rate of infusion, ensuring accurate patient care and monitoring during the transfusion process.
