    PEEP improves oxygenation in ARDS but does not guarantee a survival advantage, as physiological benefits may be offset by systemic consequences.

  • 2

    Elevated central venous pressure and reduced urine output can occur with PEEP, indicating adverse systemic effects despite improved respiratory function.

  • 3

    Venous congestion in ARDS is linked to impaired venous drainage and reduced perfusion gradients, affecting organ function even with preserved arterial pressure.

  • 4

    Mechanical profiles in ARDS influence the circulatory response to PEEP, highlighting the importance of lung recruitability and pressure transmission.

  • 5

    PEEP titration should consider systemic effects, making it a systemic decision rather than solely a respiratory adjustment in ARDS management.
