Embodiment Construction

[0057] The present disclosure relates to an automated lung recruitment procedure for reopening collapsed alveoli in a mechanically ventilated patient. The recruitment maneuver may be performed automatically by the breathing apparatus providing mechanical ventilation to the patient. The recruitment maneuver can be implemented entirely in software, allowing conventionally equipped breathing apparatus to perform the maneuver without modifying existing hardware.

[0058] figure 1 Illustrated is an exemplary embodiment of a mechanical ventilation system 1 comprising a breathing apparatus 2 configured to perform a self-recruitment maneuver according to the principles disclosed herein. The breathing device 2 may be any type of device capable of providing mechanical ventilation to the patient 3 by supplying pressurized breathing gas to the airway of the patient 3 . Ventilators and anesthesia machines are non-limiting examples of such breathing devices.

Abstract

The present disclosure relates to a ventilation system (1) comprising a breathing apparatus (2) for providing mechanical ventilation to a patient (3). The breathing apparatus is configured to performan 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 (2) is further configured to automatically switch ventilation mode to a predefined ventilation mode after the FRM manoeuvre, and to ventilate the patient (3) 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.

Description

technical field [0001] The present disclosure relates to the field of mechanical ventilation, and in particular to a ventilation system, method and computer program for lung recruitment of mechanically ventilated patients. Background technique [0002] Over the past few years, in order to reduce the risk of ventilator-induced lung injury (VILI) in mechanically ventilated patients with acute respiratory distress syndrome (ARDS), recruitment maneuvers (RM) have been used to overcome lung collapse (atelectasis). ) and improving lung function have attracted attention. [0003] If some areas of the lung are poorly inflated with alveolar collapse, the patient will be poorly ventilated, requiring higher driving pressures and FiO 2 Set so that the patient is adequately oxygenated. During these conditions, if the alveoli repeatedly expand and collapse, there is a risk of exacerbated lung damage and increased risk of prolonged hospitalization and death. [0004] By applying a lung-...
