  • Page 28 3.3.3 AirTrap Control AirTrap Control monitors ventilation with regard to possible air-trapping to prevent overinflation of the lung or dynamic hyperinflation. This function is particularly suitable for supplementing therapy in the case of obstructive clinical pictures (e.g. COPD). If breath curves indicate air-trapping and a rise in intrinsic PEEP, frequency is reduced, with inspiration time remaining constant.
  • Page 29 3.3.5 Volume compensation Activating volume compensation ensures that the patient is supplied a minimum volume. To this end, the tidal volume determined for the patient is compared to a set minimum volume.
