WARNING
• Use only medical grade oxygen sources.
•
Always ensure that the device is ventilating before the oxygen supply is turned on.
• Oxygen flow must be turned off when the device is not ventilating so that oxygen does not
accumulate within the device enclosure. Explanation: Accumulation of oxygen presents a risk
of fire. This applies to most types of ventilators.
•
Oxygen supports combustion. Oxygen must not be used while smoking or in the presence of
an open flame. Only use oxygen in well-ventilated rooms.
• Supplemental oxygen must be added into Astral's oxygen inlet at the rear of the device.
Adding oxygen elsewhere, ie, into the breathing system via a side port or at the mask, has
potential to impair triggering and accuracy of therapy/monitoring and impair alarms (eg, High
Leak alarm, Non-vented mask alarm)
•
The patient circuit and the oxygen source must be kept at a minimum distance of 2 m away
from any sources of ignition.
•
Monitor supplemental oxygen using the integrated FiO
fraction of inspired oxygen, use an external O
Sampling should be taken from the connection to the patient interface.
•
When operating Astral in its mobility bag do not add more than 6 L/min of supplemental
oxygen.
• Astral is not designed for use with heliox, nitric oxide or anesthetic gases.
•
Do not position the Astral device on its side as this may affect FiO
To add supplemental oxygen:
1. Unlock the low flow oxygen inlet at the rear of the device by pushing up on the locking clip.
2. Insert one end of the oxygen supply tubing into the oxygen connector port. The tubing will
automatically lock into place.
3. Attach the other end of the oxygen supply tubing to the oxygen supply.
4. Start ventilation
5. Turn on oxygen and adjust to the prescribed flow rate or FiO
Supplemental oxygen can also be added from an oxygen bottle (at 400kPA) however a flow regulator
must be fitted to ensure the delivered oxygen remains at or below 30 L/min.
Before you remove supplemental oxygen from the device, ensure the Oxygen supply has been turned
off.
