NCT03296293

Brief Summary

The impact of PEEP on ICP was dependent on the difference between elevated CVP levels and baseline ICP levels. ICP would increase once elevated CVP through PEEP adjustment exceeds the baseline ICP.

Outcome Measures

Primary Outcomes (1)

  • Effects of positive end-expiratory pressure on intracranial pressure in patients with severe traumatic brain injury

    The impact of PEEP on ICP was dependent on the difference between elevated CVP levels and baseline ICP levels. ICP would increase once elevated CVP through PEEP adjustment exceeds the baseline ICP.

    up to 12 months
