I am doing research. Let me rephrase that. I am trying really hard to find some research on the benefits of using gravity to infuse blood over using an infusion pump. I have read in numerous hospital policies that the use of an infusion pump is not allowed unless special circumstances call for the use of one. I have heard or read from multiple sources that the use of an infusion pump causes hemolysis and increases the risk of thrombus formation. I find it hard tho to find research to support this. Could someone please help me by submitting any articles you know of to support or deny this information. Thank You
