Chest Compression only CPR Update

It is a lot of time unfortunately; the first sign of cardiovascular disease is all too often the last sudden cardiac death and cardiac arrest. A 40-year-old American male has a 1 in 8 chance of having sudden cardiac death during his lifetime. The majority of OHCAs in adults are due to an acute coronary artery occlusion. A major reason for the lack of bystander CPR was the requirement for mouth-to-mouth ventilations as the first step in CPR. Most bystanders would call 911, but then await EMS arrival. In swine model of VF arrest, survival was better with CO-CPR 73% than with no CPR until defibrillation at 10 minutes which was 13% only. During the Circulatory Phase of VF Arrest, An adequate Coronary Perfusion Pressure is necessary for ROSC following Defibrillation . Unfortunate during ventilation, an average of 16 second passes which lead to prolonged drop in coronary perfusion pressure to zero. Furthermore, in patients with primary cardiac arrest, who were breathing normally at the time of their arrest, their arterial blood system is normally saturated and since it is not circulating, it remains saturated for a long time. Meta-Analysis of Randomized Trials of EMS Dispatcher Assisted CO-CPR. Survival of patients with OHCA treated with chest-compression only CPR was significantly better (Hüpfl et al. Lancet 2010; Oct 15). (...)
