Common Issues with 22mm Circuit Tubing and How to Troubleshoot


22mm circuit tubing is widely used in medical and respiratory equipment to deliver oxygen and other gases to patients. However, like any other equipment, it is prone to certain issues that can affect its functionality. In this article, we will discuss some common issues that may arise with 22mm circuit tubing and provide troubleshooting tips to resolve them effectively.

1. Tube Disconnections:

One of the most common issues that users encounter with 22mm circuit tubing is tube disconnections. This can occur when the tubing is not securely connected to the respiratory equipment or when there is excessive movement of the patient. To troubleshoot this issue, make sure that all connections are securely tightened and use tubing clips or straps to keep the tubing in place. Regularly inspect the connections and replace any worn-out or damaged parts.

2. Tube Blockages:

Another issue that users face is blockages in the tubing, which restrict or prevent the flow of gases. This can be caused by the accumulation of mucus, condensation, or debris. To troubleshoot this issue, regularly clean and disinfect the tubing as per the manufacturer’s guidelines. Additionally, ensure the patient is adequately hydrating to reduce the risk of mucus buildup. If a blockage occurs, try clearing it by gently blowing air through the tubing or using a small, soft brush to remove any debris.

3. Tube Leaks:

Leakage of gases from the tubing can negatively impact oxygen delivery and compromise the effectiveness of respiratory therapy. This issue can be caused by loose connections, cracks in the tubing, or improper installation of equipment. Troubleshoot this issue by thoroughly inspecting the tubing for any visible cracks or damage. Ensure all connections are tightened and properly aligned. If needed, replace worn-out or damaged tubing with new ones, following the manufacturer’s recommendations.

4. Tube Condensation:

Condensation can often accumulate inside the tubing, leading to discomfort for the patient and obstruction of gas flow. To troubleshoot this issue, try using a tubing cover or insulation sleeve to prevent the formation of condensation. Regularly inspect the tubing for any signs of moisture buildup, and dry it thoroughly using a soft cloth or towel. If the issue persists, consult the equipment manufacturer or a healthcare professional for further assistance.

5. Tube Length/Compatibility:

Sometimes, users may face issues with the length or compatibility of 22mm circuit tubing with their specific equipment. It is crucial to ensure the tubing length is appropriate for the designated purpose, as using tubing that is too long or too short can affect gas flow and cause discomfort. Check the equipment manual or consult with the manufacturer to determine the recommended tubing length for your specific needs. Additionally, verify the compatibility of the tubing material with the equipment in use to ensure optimal performance.


Being aware of the common issues and troubleshooting tips associated with 22mm circuit tubing can help users ensure the smooth operation of respiratory equipment and provide effective care to patients. Regular inspection, maintenance, and proper handling of the tubing can significantly reduce the occurrence of issues and enhance patient comfort and safety. If in doubt, always consult the equipment manufacturer or seek advice from a healthcare professional for appropriate guidance.
