Changing IV to an Intermittent Device
IV to Intermittent Device
- Check physician's order
- Check patient's IV site to identify needed supplies: Intermittent injection cap, extension tubing
- Prepare equipment: withdraw 2-3 ml normal saline solution into a 5 ml syringe, attach access pin/blue clave connector/your hospital's adapter.
Using a 5 ml syringe ensures that vein damage will not occur during injection of the flush solution. The smaller the syringe, the greater pressure it can exert on the venous wall.
|4. Close clamp on IV tubing and IV extension set.|
|Disconnect the tubing from the injection port by sqeezing the "wings" on the lever lock cannula|
5. Wipe injection cap with alcohol. Do not let go of injection cap after it has been cleaned.
|6. Insert syringe filled with 2-3 ml of normal saline flush solution (follow agency policy)|
|Open clamp if present|
|7. Briefly aspirate to check for patency, then inject the normal saline flush solution.|
|Close clamp if present|
A critical step is closing the clamp before removing the syringe because it prevents clot formation in the IV cannula.
