NCT06836830

Brief Summary

Out-of-hospital cardiac arrest (OHCA) remains a major cause of mortality, with low survival probabilities to hospital discharge. Despite the frequent use of airway management and mechanical ventilation during resuscitation, there is limited evidence regarding the optimal ventilation strategy to improve oxygen delivery and patient outcomes. The present study aims to investigate the effects of positive-end-expiratory-pressure (PEEP) set at 5 mbar compared to zero-end-expiratory-pressure (ZEEP) on the return of spontaneous-circulation (ROSC) in adult patients with OHCA.

Outcome Measures

Primary Outcomes (1)

  • The return of spontaneous circulation (ROSC)

    The primary outcome is the ROSC, defined according to the Utstein template by the presence of a palpable pulse during or after resuscitation. This will be measured as a binary outcome (palpable pulse, yes or no).

    During or after resuscitation

Secondary Outcomes (6)

  • Re-Arrest-Rate

    Upon hospital admission

  • Death during pre-hospital care phase

    Upon hospital admission

  • Hospital admission during ongoing resuscitation

    at hospital admission

  • Hospital admission with spontaneous circulation

    at hospital admission

  • SpO2 at hospital admission

    at hospital admission

  • +1 more secondary outcomes
