should position their line of sight within an angle of 30 degrees from a
plane perpendicular to the screen.
The Astral device complies with IEC60601-1:2005 legibility requirements.
*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.
** To achieve specified accuracies, a successful Learn Circuit must be performed.
*** Limits are the sum of device and circuit impedance.
**** 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
cell will last for 20 000 hours at 50% FiO
