201-1 Homework Assignment 2

In this study 114 EMS agencies participated in finding evidence to support or deny that during

cardiopulmonary resuscitation the interruption of manual CPR for rescue breathing reduces blood flow

and possibly survival. Assessed, was outcomes after continuous compressions with positive-pressure

ventilation differed from those after compressions that were interrupted for ventilations at a rate of

30:2. The intervention group consisted of adults with non-traumatic related cardiac arrests received

continuous chest compressions, while interrupted chest compressions were the control group. Rate of

survival to hospital discharge was the primary outcome.

Results in 23,711 patients showed that CPR performed by EMS providers did not result in

significantly higher rates of survival or favorable neurologic function than did interrupted chest

compressions. Of the 23,711 patients, 12,653 were assigned to the intervention group, and 11,058 to

the control group (Continuous or Interrupted Chest Compressions During CPR 2016). A total of 1129 of

12,613 patients with available data (9.0%) in the intervention group and 1072 of 11,035 with available

data (9.7%) in the control group survived until discharge (Continuous or Interrupted Chest Compressions

During CPR 2016).

Based on the results shown, I do not have any confounding reasons to doubt the results. Those

that participated in the study were able to find an accurate conclusion based off of having a reasonably

large sample size as well as demographic population. The results that they were looking for, were also

rather definitive, which was survival during nontraumatic cardiac emergencies. The impacts this study
