1. Patient Connection Error: Make sure that the oxygen tubing is correctly connected to the oxygen port on the bi-level ventilator and that the connection is tightened securely. Make sure that the oxygen source is turned on and that the oxygen tubing is not leaking.
2. Equipment malfunction: If the oxygen concentration cannot be adjusted no matter how the bi-level ventilator is operated, there may be an equipment malfunction. A medical device technician should be contacted to repair or replace the device.
3. Lack of privileges: Some bi-level ventilators may have privileges that allow only a physician or certain medical professionals to adjust oxygen levels. If you do not have the appropriate permissions, you should seek the help of a doctor or technician.
If none of these methods solves the problem, it is recommended that you contact a doctor or medical device technician as soon as possible for assistance and examination to ensure that the bi-level ventilator is working properly and providing the patient with the appropriate oxygen concentration.
