Step 23: Check for a blood return
- Check for a blood return after every 5 to 10 cc of factor you inject.
- Pull back slowly on the plunger of the syringe. Blood will enter the tubing if you are still in the vein.
- If there is no blood return, remove the needle and press down on the site. Try again at another site with a new needle. Use the factor as soon as possible. Factor that has been mixed up should not sit for hours before infusing. When in doubt, check with your HTC.
Caution: Do not pull back on the plunger so much that the blood comes back into the syringe.
