This device is not suitable for use in the presence of a flammable anaesthetic mixture.
The International ventilator standard indicates that Paediatric patient type is intended to be used for a patient receiving less
1
than 300 mL, however Astral permits adjustment of 'Vt' setting parameter up to 500 mL for cases where 'Vt' is set such that it
compensates for leak in the breathing circuit.
WARNING
ResMed does not recommend 500 mL as the upper limit for the paediatric tidal volume use;
however, clinicians may choose this upper limit based on their clinical determination.
2 To achieve specified accuracies, a successful Learn Circuit must be performed.
3 Limits are the sum of device and circuit impedance under single fault leading to device shutdown.
Individual configurations may be more sensitive.

The life of oxygen cells is described by hours used multiplied by the % of oxygen used. For example, 1 000 000 % hours oxygen
5
cell will last for 20 000 hours at 50% FiO
oxygen cell will last for 25,000 hours (1041 days) at 40% FiO
