The aim of the study was to test if instruction without visual directions is sufficient to obtain the recommended hand position for cardiopulmonary resuscitation (CPR).
Group A (n = 12) was verbally instructed to "place the heel of the hand in the center of the chest." Group B (n = 10) was verbally instructed to "place the heel of the hand in the middle of the lower half of the breastbone." Subsequently, both groups again received the same verbal instruction aided by visual directions. The distance from the recommended hand position was compared before and after visual directions.
Five participants in Group A (42%) and 1 in Group B (10%) placed their hands in the epigastrium. In both groups, hand position significantly improved after visual directions (Group A: 5.7 ± 2.4 vs 2.1 ± 0.8 cm, P < .001, and Group B: 4.5 ± 2.5 vs 2.0 ± 1.2 cm, P = .005).
Instruction including visual direction was superior to verbal instruction only in obtaining hand position for CPR.
本研究旨在检验在没有视觉指导的情况下，是否足以获得推荐的心肺复苏（CPR）手放置位置。
A 组（n=12）口头指导“将手掌根部放在胸部中央”。B 组（n=10）口头指导“将手掌根部放在胸骨下半部分的中间”。之后，两组均再次接受相同的口头指导，并辅以视觉指导。比较视觉指导前后推荐手放置位置的距离。
A 组有 5 名（42%）参与者和 B 组有 1 名（10%）参与者将手放在上腹部。两组的手放置位置在视觉指导后均显著改善（A 组：5.7±2.4 厘米比 2.1±0.8 厘米，P<0.001；B 组：4.5±2.5 厘米比 2.0±1.2 厘米，P=0.005）。
在获得 CPR 手放置位置方面，包含视觉指导的指导优于仅口头指导。
