Abstract (en)
[origin: WO2022184471A1] The invention relates to a calibration system (60) for automatically setting an intended operational filling of an esophagus catheter (48) with a balloon probe (46) for the purposes of determining an esophageal pressure (Peso), the esophagus catheter being insertable into the esophagus (34) and serving in particular for a ventilation apparatus (10), the calibration system comprising an arrangement for filling the balloon probe (46) with a measuring fluid after placing the balloon probe (46) into the esophagus (34), a pressure sensor for detecting the esophageal pressure (Peso) prevalent in the balloon probe (46), and a calibration controller (60) designed such that it incrementally changes the amount of measuring fluid in the balloon probe (46), the calibration controller (60) recording an esophageal pressure (Peso) detected by the pressure sensor for each amount of measuring fluid in the balloon probe (46) set incrementally as a measuring point in this way and assigning the esophageal pressure to the respective set amount of measuring fluid in the balloon probe (46). The calibration controller (60) is designed such that it monotonically changes the amount of measuring fluid in at least two steps to reach an end value starting from a start value, for the purposes of homing in on the respective measuring points.
