Specific Astral Problem Solving
Condensation in breathing
circuit
See ‘Troubleshooting the Humidifier’
Check the circuit is the right type and set up correctly.
Check the circuit for leaks.
Repeat the ‘learn circuit’ (try with circuit straight)
If double-limb circuit, check the expiratory adaptor and the module
beneath it – check the blue membrane and sensor are pushed down flush
with the enclosure.
This may indicate the circuit being used is higher resistance than the Astral
expects. This is still safe to use but discuss with your health team.
Check the circuit for water, leaks or faults.
Perform a learn circuit.
If alarm persists, replace circuit + do another learn circuit.
Consider alternative ventilator/circuit.
Contact your health team.
Touch screen damaged or
unresponsive
Check on your child.
Switch to alternative respiratory support.
Try powering on/off the device.
If you can’t do this normally then disconnect the mains power, press and
hold both the green on/off button and the alarm mute button for at least
10 seconds. After 10 seconds the alarm button will flash. Release the
buttons. It will power down and can then be restarted as usual.
If this doesn’t resolve the problem, contact your health team.
