Recent studies have shown that bystander compression-only cardiopulmonary resuscitation (CPR) provides equal or superior outcomes to traditional CPR for adult cardiac arrest victims (JW Emerg Med Jul 28 2010 and JW Emerg Med Oct 22 2010). To further examine this association, researchers conducted a two-part meta-analysis of studies published between 1985 and August 2010 that compared survival outcomes for compression-only CPR and traditional CPR in adults with out-of-hospital cardiac arrest.
In the primary meta-analysis, pooled data from three randomized trials (3031 patients) demonstrated significantly increased survival (at hospital discharge or 30 days) with dispatcher-assisted compression-only CPR, compared with dispatcher-assisted tradi…
