Estimated using 50 ml/kg ratio.

Ventilation Characteristics

Specification	Conditions	Minimum	Typical	Maximum	Units
Ventilation frequency⁴	Based on 1:1 I:E (max varies with subject weight)	6	_	600	br/min
I:E ratio⁴	_	1:7	2:3	2:1	_
PEEP⁵	Computer controlled	0	3	20	cmH₂O
Pressure range⁶	_	-80	_	80	cmH₂O
Control modes⁷	Mechanical (e.g 10 ml/kg displaced) or Pressure (e.g. peak cylinder) controlled ventilation
Gas supply	Room air or non-flammable mixed gas

The I:E ratio in the software is expressed as a percentage of the exhalation time that the inhalation time lasts, e.g. the default 2:3 I:E ratio is expressed as 67%, a 1:1 ratio is expressed as 100%.
The lower limit for computer-controlled PEEP is on the order of 0.25-0.5 cmH2O and may vary slightly from one configuration to the next. The minimum of 0 cmH2O reflected in the table is achievable if the option for PEEP control is set to ‘External’ in the ventilation pattern definition dialogue.
Linearity of the transducers is only guaranteed up to ± 76.2 cmH2O
Software controlled ventilation modes are predefined by user.
