PC 1730 – Drive gas for rebreathing
Type of ventilation depends on the following settings:
• Mode of ventilation.
• Breathing system – Circle System/Non-Rebreathing
or Auxiliary Fresh Gas Outlet.
• Volume – When Circle System/VC is selected.
• Press. Level above PEEP – When Circle System/PC
and PS is selected.
• Respiratory frequency – CMV (b/min).
• Inspiration time – I:E Ratio.
• Trigger Sensitivity
• PEEP.
