Brief Summary:
The study is aimed to assess (a) the incidence of hyperoxia at the point of return of spontaneous circulation (ROSC) and (b) the role of arterial blood oxygen partial pressure to brain oxygenation during out-of-hospital cardiac arrest. 80 adult patients will be recruited in a physician staffed helicopter emergency medical services. Brain regional oxygen saturation and invasive blood pressure are monitored until hospital admission and arterial blood gases are analyzed immediately when the unit arrives to the patient and again at the time of ROSC.

Intervention Details:
  • Other: Standard cardiopulmonary resuscitation
    Standard Advanced Life Support based on guidelines 2015, including mechanical chest compression device

Primary Outcome Measures :
  1. Arterial oxygen partial pressure [ Time Frame: 5-60 minutes ]
    Arterial oxygen partial pressure at the time of return of spontaneous circulation (ROSC)

Secondary Outcome Measures :
  1. Forehead regional oxygen saturation during resuscitation [ Time Frame: 0-60 minutes ]
    Oxygen saturation measured using near-infrared spectroscopy

Sampling Method:   Non-Probability Sample
Study Population
All adult patients met in cardiac arrest by the physician-led prehospital critical care team are to be screened and recruited based the eligibility criteria. The patients include patients in all primary rhythms.

Inclusion Criteria:

  • out-of-hospital cardiac arrest of presumed cardiac origin
  • resuscitation will be continued at least 5 minutes (if return of spontaneous circulation not achieved earlier) after arrival of physician team

Exclusion Criteria:

  • do-not-attempt-resuscitation (DNAR) order or withdrawal of treatment by prehospital critical care physician
  • return of spontaneous circulation achieved before physician-led critical team arrives
  • external cause for cardiac arrest (e.g. trauma, suffocation)
  • workload too high or environment too dangerous to perform study procedures
