Measuring cardiopulmonary resuscitation performance: a comparison of the Heartsaver checklist to manikin strip.

Both checklists and recording manikin strips (strips) are used for evaluation of cardiopulmonary resuscitation (CPR) performance. To examine their relationship, we simultaneously evaluated single rescuer CPR of 255 subjects using both checklists and strips. For Group 1 (N = 192; general public tested in Heartsaver course) we compared the total number of initial ventilations and compressions judged to be correct by checklists with those judged to be correct by strips. For Group II (N = 63; physicians, nurses, general public tested in retention studies) we compared each subjects checklist with their own strip for evaluation of correct ventilations and compressions. In Group I, CPR was judged to be correct two to four times more frequently by checklists than by strips. In Group II, all correlations were poor. The most common disagreements were with performances evaluated as correct by checklist but not by strip. Therefore, the current checklist may be a poor instrument for measuring CPR. More accurate evaluation should improve learning and therefore improve outcome following cardiac arrest.
