Comparative Study
Persisting effect of community approaches to resuscitation.
On the Danish island of Bornholm an intervention was carried out during 2008-2010 aiming at increasing out-of-hospital cardiac arrest (OHCA) survival. The intervention included mass media focus on resuscitation and widespread educational activities. The aim of this study was to compare the bystander BLS rate and survival after OHCA on Bornholm in a 3-year follow-up period after the intervention took place. ⋯ In a 3-year follow-up period after an intervention engaging laypersons in resuscitation through mass education in BLS combined with a media focus on resuscitation, we observed a persistent significant increase in the bystander BLS rate for all OHCAs with presumed cardiac aetiology. There was no significant difference in 30-day survival.

A 10-fold regional variation in survival after out-of-hospital cardiac arrest (OHCA) has been reported in the United States, which partly relates to variability in bystander cardiopulmonary resuscitation (CPR) rates. In order for resources to be focused on areas of greatest need, we conducted a geospatial analysis of variation of CPR rates. ⋯ In 3 counties in North Carolina, areas with low rates of bystander CPR can be identified using geospatial data, and education efforts can be targeted to improve recognition of cardiac arrest and to augment bystander CPR rates.

The use of capnography is recommended during resuscitation. By implementing the mnemonic "PQRST", rescuers have a ready-made checklist to help them achieve the full potential of capnography. This approach can facilitate efforts to both reduce the hands-off time and individualize the treatment, which can lead to improved survival for our patients.

Performing exercise is shown to prevent cardiovascular disease, but the risk of an out-of-hospital cardiac arrest (OHCA) is temporarily increased during strenuous activity. We examined the etiology and outcome after successfully resuscitated OHCA during exercise in a general non-athletic population. ⋯ OHCA occurring during exercise was associated with a significantly lower mortality in successfully resuscitated patients even after adjusting for confounding factors. Acute coronary syndrome was more common among exercise-related cardiac arrest patients.

TrueCPR is a new real-time compression depth feedback device that measures changes in magnetic field strength between a back pad and a chest pad. We determined its accuracy with a manikin on a test bench and on various surfaces. ⋯ TrueCPR measures depth precisely, independent of the stiffness of the surface upon which the CPR is being performed with a constant inaccuracy of <4.5mm. A sternum-only accelerometer substantially overestimates depth when performing CPR on a soft surface. Correction for body displacement on a soft surface is essential for accurate delivery of chest compressions within the recommended depth range.
