- Visible wear and tear, cracks, or holes.
- Difficulty cleaning or persistent odors.
- Reduced heating efficiency or inconsistent air delivery.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No heat from tube / Tube not warming up. | Improper connection to CPAP machine; Heated tube setting off; Damaged heating element. | Ensure tube is securely connected and electrical pins are aligned. Check CPAP machine settings to confirm heated tube function is enabled. If problem persists, the tube may be faulty and require replacement. |
| Condensation (rainout) in tube. | Room temperature too cold; Humidity setting too high; Tube not heating properly. | Increase room temperature if possible. Lower the humidity setting on your CPAP machine. Verify heated tube is functioning correctly as per above. |
| Air leakage from tube connections. | Loose connection; Damaged tube ends. | Ensure all connections are firm and secure. Inspect tube ends for cracks or damage; replace tube if damaged. |
| Unusual odor from tube. | Insufficient cleaning; Tube needs replacement. | Clean the tube thoroughly as per maintenance instructions. If odor persists, replace the tube. |
