What this Trial Is About

Researchers are evaluating how accurately both laypersons and health-care providers can estimate length and depth, specifically a 5cm line and a 5cm depth. The study aims to assess the ability of these two groups to make these estimations without assistance, based on the hypothesis that both groups may have difficulty estimating length and depth accurately. The study will enroll 100 participants from each group, focusing on adults related to cardiopulmonary resuscitation contexts. Participants will be asked to perform two tasks: first, to draw a line measuring 5cm; and second, to press a depth measuring device and a resuscitation training manikin to a depth of 5cm, both without and with assistance. These tasks are designed to measure their accuracy in length and depth estimation. The main measurement is the depth estimation accuracy, which will be recorded immediately after participants arrive at the study site and complete the protocol, taking less than 5 minutes. Participants include adult laypersons without recent CPR training and active health-care providers. The study involves no long-term follow-up, focusing on immediate assessment during one visit.
