Patient Circuit Performance Issues

Follow these steps to troubleshoot issues with the patient circuit performance:

1. Ensure connected patient circuit accessories (such as an HME or humidifier) are clean and not obstructed.
2. Run a Pre-Use Test. If the circuit passes the Pre-Use Test, it is working as intended.
3. If the circuit will not pass the Pre-Use Test, see Why Is the Pre-Use Test Failing?
