ABSTRACT
BACKGROUND:
Recent studies have demonstrated higher-quality chest compressions (CCs) following a 60 s ultra-brief video (UBV) on compression-only CPR (CO-CPR). However, the effectiveness of UBVs as a CPR-teaching tool for lay bystanders in public venues remains unknown.OBJECTIVE:
Determine whether an UBV is effective in teaching laypersons CO-CPR in a public setting and if viewing leads to superior responsiveness and CPR skills.METHODS:
Adult lay bystanders were enrolled in a public shopping mall and randomized to (1) Control (CTR) sat idle for 60 s; (2) UBV watched a 60 s UBV on CO-CPR. Subjects were read a scenario detailing a sudden collapse in the mall and asked to do what they "thought was best" on a mannequin. Performance measures were recorded for 2 min responsiveness (time to call 911 and first CCs) and CPR quality [CC depth, rate, hands-off interval (time without CC after first CC)].RESULTS:
One hundred subjects were enrolled. Demographics were similar between groups. UBV subjects called 911 more frequently (percent difference 31%) and initiated CCs sooner in the arrest scenario (median difference (MD) 5 s). UBV cohort had increased CC rate (MD 19 cpm) and decreased hands-off interval (MD 27 s). There was no difference in CC depth.CONCLUSION:
Bystanders with UBV training in a shopping mall had significantly improved responsiveness, CC rate, and decreased hands-off interval. Given the short length of training, UBV may have potential as a ubiquitous intervention for public venues to help improve bystander reaction to arrest and CO-CPR performance.Palavras-chave
