Is Continuous Compression Better than 30:2 Ratio?

Is Continuous Compression Better than 30:2 Ratio?

A recent study (2016) measured the CPR quality during 5 minutes of chest compressions. They had some participants perform continuous chest compressions, and others perform 30 compressions and give two breaths (30:2). After 5 minutes, they found that participants were able to deliver more compressions if they did not stop to give breaths (that’s a no-brainer). However, there was a faster decline in CPR quality in this group, as compared to those who performed CPR using the 30:2 method. This means that the decline in CPR quality occurred as a slower rate among those using the 30:2 method. What is interesting about their findings is that those who performed continuous chest compressions provided more quality compressions per minute than those using the 30:2 method.

There are some limitations to this study, however. For one, the average age of their participants was 70 years old. To justify recruiting participants of this age, the authors argued that those aged 55 years or older are most likely to perform CPR. So before we generalize this finding to all populations, we must keep the recruited population in mind.
