A ventilation system includes a breathing apparatus which provides a mechanical ventilation to a patient. The breathing apparatus is configured to perform an automated full recruitment manoeuvre, FRM, comprising a recruitment phase and a PEEP titration phase, wherein the PEEP titration phase is a phase of stepwise decrease in PEEP from a maximum PEEP level to a minimum PEEP level, via one or more intermediate PEEP levels. The breathing apparatus is configured to deliver a number of breaths at each PEEP level, and to monitor a parameter indicative of a potentially harmful level of ventilation during the PEEP titration. The breathing apparatus is further configured to automatically decrease PEEP to a lower PEEP level when the monitored parameter reaches a first threshold value.

Lung recruitment in mechanical ventilation

A ventilator provides breathing support to a patient in an EMG controlled mode, and has an input that receives an EMG signal representative of breathing activity from the patient and a control unit for controlling the ventilation in dependence of said EMG signal. The ventilator has a registration unit that registers the actual breathing support provided from the ventilator to the patient, and the control unit determines if there is asynchrony between the EMG signal and the breathing activity and, in case of asynchrony, causes a switch from EMG controlled ventilation to a second ventilation mode not dependent on the EMG signal. If synchrony is detected the ventilator can return to EMG controlled ventilation.
