Survival From Out-of-Hospital Cardiac Arrest After Chest Compression–Only CPR

JAMA. 2011;305(2):147-148. doi:10.1001/jama.2010.1951

To the Editor: Dr Bobrow and colleagues1 concluded that compression-only cardiopulmonary resuscitation (COCPR) is superior to conventional CPR in patients who experienced out-of-hospital cardiac arrest based on the observation of better overall survival and survival with good neurologic outcome (Cerebral Performance Category [CPC] score grade 1 or 2). Although a higher percentage of patients undergoing COCPR survived (ie, had CPC score <5) and, compared with the total number of patients observed, the percentage of survivors with good outcomes was highest in this group, there is an alternative interpretation of their data.
