1. A ventilation system, comprising:
a breathing apparatus providing mechanical ventilation to a patient, the breathing apparatus being configured to perform an automated full recruitment maneuver, FRM, comprising a recruitment phase and a PEEP titration phase, and to determine at least one optimized ventilation setting for the patient during the FRM maneuver, the breathing apparatus further being configured to automatically switch ventilation mode to a predefined ventilation mode after the FRM maneuver, and to ventilate the patient in the predefined ventilation mode using the at least one optimized ventilation setting during a period of post-recruitment maneuver, post-RM, ventilation following the FRM maneuver,
wherein the predefined ventilation mode is automatically set by the breathing apparatus to correspond to a previous ventilation mode including a type of control mode via which ventilation is provided during a baseline ventilation preceding the FRM maneuver, and
wherein the breathing apparatus is configured to:
prompt a user to acknowledge the at least one optimized ventilation setting, and to use the at least one optimized ventilation setting during a period of new baseline ventilation following the post-RM period only if acknowledged by the user,
collect a first set of comparison data during ventilation of the patient in the previous ventilation mode used during baseline ventilation preceding the FRM maneuver:
collect a second set of comparison data during post-RM ventilation in the previous ventilation mode using the at least one optimized ventilation setting,
present evaluation data, which evaluation data comprises or is derived from the first and second sets of comparison data, and
prompt for an acknowledgement of the at least one optimized ventilation setting in view of the evaluation data.
