Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The application of positive end expiratory pressure is recommended but the question remains "How to set the best positive end-expiratory pressure (PEEP) level for each patient? ". Different titration techniques have been studied on oxygenation and respiratory mechanics parameters without reaching a consensus. Currently we have a module that is connected to the ventilator to collect the patient's lung volume. It will therefore allow us to optimize the settings of the ventilator and to set the best level of positive end-expiratory pressure "best peep" in order to individualize our treatment for each patient.
