10 Questions
What is the goal of blood preservation?
To increase RBC viability
How is RBC viability measured?
By assessing free hemoglobin levels
What does increased free Hgb levels indicate?
Decreased RBC viability
Why is it important to maintain red cell integrity throughout the shelf-life of stored RBCs?
To reduce the risk of hemolysis after transfusion
How are new preservation solutions and storage containers evaluated?
By evaluating free Hemoglobin levels over time
What happens to the percentage of hemolysis with the day of storage?
It progressively increases
How is post-transfusion RBC survival determined?
By reinfusing labeled RBCs to the original donor
'24-hour post-transfusion RBC survival at outdate' can be less than 75% due to what factor?
'Critically ill patients' low RBC survival rate
'The less the free haemoglobin over time, the more effective the preservative' - What does this statement suggest about preservative effectiveness?
'Less free hemoglobin' indicates better preservation
'The percentage hemolysis progressively increases with the day of storage' - What does this statement imply about stored RBCs?
'Storage time' increases the risk of hemolysis
Test your knowledge about the preservation of red blood cells (RBC) and the measures taken to maintain their viability and integrity during storage for transfusion. Explore the important factors and techniques involved in ensuring the functionality of blood components.
