WARNING
•
To prevent the risk of cross-contamination, a bacterial/viral filter is mandatory if the device is to
be used on multiple patients.
• The expiratory module, internal bacterial/viral filter, expiratory flow sensor and blue membrane
come into contact with exhaled gases but do not form part of the inspiratory pathway.
Adding supplemental oxygen
Oxygen may be prescribed by your clinician.
The Astral device is designed to be compatible with levels of supplemental oxygen up to 30 L/min.
At a fixed rate of supplemental oxygen flow, the inhaled oxygen concentration will vary depending on the
