The prognosis of cardiac arrest patients is generally poor. Recent studies have showed that the high quality of CPR increases the survival after cardiac arrest. Therefore the investigators planned this prospective observational study to determine the epidemiology of sudden cardiac arrest in the prehospital setting of Tampere area, the quality of the CPR, and also the associations between depth and frequency of chest compressions and invasive arterial pressure, EtCO2,cerebral oxygenation and iatrogenic injuries associated to chest compressions 1) in patients resuscitated out of hospital by emergency medical service's (EMS's) personals and 2) in-hospital by hospital resuscitation team members. In addition, the investigators will analyze the effects of the chosen method of resuscitation on critical vital signs (Etco2 and invasive pressures): closed-chest CPR is compared to open-chest CPR, or mechanical CPR with a device (AutoPulse-CPR, Cardio Pump) compared to manual CPR guided with quality CPR device. The results will give the investigators important insights into the haemodynamics of CPR which may guide future strategies for the management of cardiac arrest. The research group is also interested in CPR related injuries and mattress effect. Quality of life after CA is evaluated among survivals and the cause of death among non-survivors.

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Prospective

Further study details as provided by Tampere University Hospital:

Primary Outcome Measures:
  • The success rate of current guidelines (depth and frequency of chest compression, epidemiology) [ Time Frame: During the resuscitation ]
  • Quality of life after CA [ Time Frame: 6 months ]
    Quality of life after CA is usually fairly good measurement of quality of resuscitation attempt

Secondary Outcome Measures:
  • Invasive arterial pressures, cerebral oxygenation (NIRS), EtCO2 [ Time Frame: During the resuscitation ]
  • survival of cardiac arrest [ Time Frame: hospital discharge ]

Other Outcome Measures:
  • Change in hemodynamics, Change in cerebral saturation, Change in quality of CPR [ Time Frame: During resuscitation ]

Estimated Enrollment: 1000
Study Start Date: November 2008
Estimated Study Completion Date: December 2018
Primary Completion Date: December 2015 (Final data collection date for primary outcome measure)
