  Purpose

The aim of the present study is to characterize the influence of an elevated positive end-expiratory pressure in patients with acute respiratory distress syndrome or acute lung injury on the cerebrovascular autoregulation.

Primary Outcome Measures:
  • Change from Baseline cerebrovascular autoregulation due to elevated positive end-expiratory pressure [ Time Frame: 1 Year ] [ Designated as safety issue: No ]
    Is there an impairment of cerebrovascular autoregulation due to positive end-expiratory pressure ventilation this will be a major side effect especial in patients with brain injury.

Groups/Cohorts Assigned Interventions
respiratory failure
patients with respiratory failure and need of high positive end-expiratory pressure ventilation.
Procedure: positive end-expiratory pressure
Elevation of positive end-expiratory failure for recruitment
Other Name: PEEP

Detailed Description:

Cerebral blood flow velocity will be measured using transcranial Doppler sonography and then correlate with the invasive arterial blood pressure curve to calculate the index of cerebrovascular autoregulation Mx (Mx>0.3 indicates impaired AR). The index of cerebrovascular autoregulation Mx was measured during baseline positive end-expiratory pressure (PEEP) levels and after lung recruitment with higher level of PEEP. The equality between this two PEEP levels was estimated and calculated with one side Wilcoxon test.
