concentration in the breathing circuit inspiratory limb.
• The print function provides a permanent record of

Drive gas supply
WARNING
1. The ventilator is designed to be driven by medical air
only.
The drive gas is set during manufacture and the
ventilator is calibrated for that gas.
Before the ventilator is used clinically for the first time,
the commissioning engineer must confirm that the drive
gas setting is set correctly to Air.
The use of any other gas will cause inaccurate operation
and may damage the ventilator, resulting in potential
injury to the patient.
1. The driving gas supply must be clean and dry to prevent
ventilator malfunction.
• Supply pressure: Air at 280 to 600 kPa (41 to 87 psi).
