Why is the Oxygen machine making a chirping sound?
The chirping sound is coming from the humidifier bottle back pressuring because the tubing’s somehow blocked. Pull the oxygen tubing through your hand to make sure it is straight, not kinked, and that nothing is sitting on the tubing. Check the cannula to make sure it is clean and clear. The prongs on the cannula may be partially blocked, and you may need to change the cannula using one of your spares.
