Caution: When Farrell valve is not working properly the pump occlusion alarm will not function. The formula will continue to back up into the Farrell valve. If this happens:
- Check tubing to see if it is kinked or clamped.
- Irrigate feeding tube (the feeding tube may be clogged).
- Change the position of the patient.
- Check the position of the Farrell valve tubing to see if it is in proper position.
- If all the above fail, call your nurse or doctor for further instructions.
