  1. Intake and Exhaust ports use Colder PMC/PLC connectors. FX Modules are shipped with mating fittings for easy connection to standard tubing sizes.
  2. Minimum and maximum weight ranges are subject to change with further development and are listed for healthy subjects.
  3. 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 --- 1:1 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
  1. 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%.
  2. 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.
  3. Linearity of the transducers is only guaranteed up to ± 76.2 cmH2O
  4. Software controlled ventilation modes are predefined by user.
