*The International ventilator standard indicates that Paediatric patient type is intended to be used for a patient receiving less
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 pediatric tidal volume use;
however, clinicians may choose this upper limit based on their clinical determination.
