Brief Summary

The corner stone of the treatment of ARDS is mechanical ventilation with high levels of positive end-expiratory pressure, also called PEEP. A high level of PEEP is recommended and frequently used. But PEEP can lower cardiac output and contribute to circulatory failure during mechanical ventilation. Nevertheless, in theory, the PEEP-induced pulmonary vascular resistance (PVR) increase could depend on the level of alveolar recruitment, but it has never been proven. Thus, the aim of this study is to determine the relation between the high-PEEP induced PVR and the alveolar recruitment or overdistension.

Outcome Measures

Primary Outcomes (1)

  • Correlation between PVR and recruitment-to-inflation ratio

    PVR collected at two levels of PEEP and the R/I ratio to assess a relationship between the two variables

    Up to hospital discharge (maximum : day 60)

Secondary Outcomes (4)

  • Relationship between the R/I ratio and blood gas analysis

    Up to hospital discharge (maximum : day 60)

  • Relationship between the R/I ratio and respiratory system compliance

    Up to hospital discharge (maximum : day 60)

  • Relationship between right ventricle size and R/I ratio

    Up to hospital discharge (maximum : day 60)

  • Relationship between PVR change and Transpulmonary gradient (TPG) according to R/I

    Up to hospital discharge (maximum : day 60)
