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
O monitor compliant with ISO 80601-2-55.

Supplemental oxygen can also be added from an oxygen bottle however, a flow regulator must be fitted
