Patent number: 11890414Abstract: 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.Type: GrantFiled: October 17, 2018Date of Patent: February 6, 2024Assignee: MAQUET CRITICAL CARE ABInventors: Sigun Israelsson, Magnus Hallbäck, Anders Häggström, Mari Andersson

Patent number: 11154673Abstract: 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.Type: GrantFiled: October 17, 2018Date of Patent: October 26, 2021Assignee: MAQUET CRITICAL CARE ABInventors: Leif Lychou, Johan Lagerborg, Sigun Israelsson

Publication number: 20210213221Abstract: 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.Type: ApplicationFiled: October 17, 2018Publication date: July 15, 2021Inventors: Mari ANDERSSON, Leif LYCHOU, Sigun ISRAELSSON

A gas monitoring apparatus can include a gas concentration monitoring module, a respiratory mechanics monitoring module and a correction module. The correction module can determine a first correction value based on the gas ingredients and the gas concentration measured by the gas concentration monitoring module, so that the respiratory mechanics monitoring module can correct respiratory mechanics parameter(s) based on the first correction value. The correcting module can also determine a second correction value based on the pressure-related quantity measured by the respiratory mechanics monitoring module, so that the gas concentration monitoring module can correct gas concentration based on the second correction value.Type: ApplicationFiled: June 16, 2014Publication date: October 2, 2014Inventors: Zhonghua Liu, Liangjun Jiang, Youqiang Tu, Jian Cen, Fangyong Guan, Guangqi Huang, Ylva Sigun Israelsson
