  • Patent number: 11890414
    Abstract: A ventilation system includes a breathing apparatus which provides 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. In the PEEP titration phase the breathing apparatus is configured to gradually decrease the level of PEEP and to deliver a number of breaths at each of a plurality of PEEP levels, monitor at least one parameter from which an optimal PEEP of the patient may be determined, predict whether the optimal PEEP will be possible to reliably determine later on during the PEEP titration phase, and automatically abort the FRM manoeuvre if it is predicted that it will not be possible to reliably determine the optimal PEEP.

  • Patent number: 11202874
    Abstract: A system is for alarm management in connection with a lung recruitment manoeuvre performed by a breathing apparatus on a mechanically ventilated patient. The system is configured to obtain information on at least one optimized ventilation setting for the patient, determined during the lung recruitment manoeuvre, and to automatically initiate at least one alarm setting for a period of ventilation following the recruitment manoeuvre, based on the optimized ventilation setting.

  • Publication number: 20210244902
    Abstract: A ventilation system includes a breathing apparatus which provides 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, and to determine at least one optimised ventilation setting for the patient during the FRM manoeuvre. The breathing apparatus is further configured to automatically switch ventilation mode to a predefined ventilation mode after the FRM manoeuvre, and to ventilate the patient in the predefined ventilation mode using the at least one optimised ventilation setting during a period of post-recruitment manoeuvre, post-RM, ventilation following the FRM manoeuvre.

  • Publication number: 20210213221
    Abstract: A ventilation system includes a breathing apparatus which provides a mechanical ventilation to a patient. The breathing apparatus is configured to perform, at a first point in time, an automated full recruitment manoeuvre, FRM, comprising a recruitment phase and a PEEP titration phase, the FRM being performed based on preset FRM settings. The breathing apparatus is further configured to perform, at a second and later point in time, an automated quick recruitment manoeuvre, QRM, comprising a recruitment phase but no PEEP titration phase, the QRM being performed based on preset QRM settings. The breathing apparatus is configured to initiate at least one QRM setting based on at least one FRM setting used for the FRM manoeuvre, and/or a result of the FRM manoeuvre.

  • Patent number: 10328221
    Abstract: An anesthetic breathing apparatus has a processing unit, a breathing circuit for providing an inspiratory patient gas mixture of re-breathed gas and/or fresh gas to a patient fluidly connected to the breathing circuit, and a fresh gas supply controllable by the processing unit for supplying a flow of the fresh gas to the breathing circuit in a composition including oxygen and at least one anesthetic agent (AA). A user interface includes a first user input element for receiving operator input for an anesthetic target value including an end expiratory concentration of the AA (EtAA) target value and/or an end expiratory minimum alveolar concentration (EtMAC) target value of an end expiratory MAC value of the patient, and a second user input element for receiving operator input for a desired control profile for the fresh gas supply for obtaining at least the anesthetic target value.
