  • System and method for determination of transpulmonary pressure in a patient connected to a breathing apparatus
    Patent number: 11154217
    Abstract: A breathing apparatus (1) is disclosed that is adapted to determine a transpulmonary pressure in a patient (125) when connected to said breathing apparatus. A control unit (105) is operable to set a first mode of operation for ventilating said patient with a first Positive End Expiratory Pressure (PEEP) level; set a second mode of operation for ventilating said patient with a second PEEP level starting from said first PEEP level; and determine said transpulmonary pressure (Ptp) based on a change in end-expiratory lung volume (?EELV) and a difference between said first PEEP level and said second PEEP level (?PEEP). Furthermore, a method and computer program are disclosed.

  • Method, system and software for protective ventilation
    Patent number: 10881822
    Abstract: A system including a breathing apparatus and a processor is configured to raise a first positive end-expiratory pressure PEEP level to at least a second PEEP level above said first PEEP level and subsequently lowering said second PEEP level to said first PEEP level and to calculate a lung mechanics equation relating total lung volume above functional residual capacity (FRC) to transpulmonary pressure (PTP) of a lung connected to said breathing apparatus, based on a change in end-expiratory lung volume (DEELV) between said first PEEP level and said second PEEP level.
