Analysis of chest compression depth and rate during cardiopulmonary resuscitation with and without a feedback device

Background:Many feedback devices have been designed to improve the resuscitation outcomes. None have been implemented as a standard in patient care.Objectives:The aim of this study was to evaluate the chest compression depth and rate during cardiopulmonary resuscitation with and without a feedback device and to evaluate differences regarding the impact of a feedback device based on provider experience.Methods:The study was performed on 20 men divided into two groups: group A (n = 10)—paramedics; group B (n = 10)—non-paramedics, trained to provide resuscitation. Participants were examined during resuscitation with Ambu Megacode manikin and with or without the feedback device—CPRmeter. Depth of compressions was evaluated in the first and fourth minute of resuscitation with a BTS Smart DX7000 motion capture system. For statistical analysis, summary statistics, Shapiro–Wilk Test of normality, dependent samples t-test, Levene test, t-test for independent samples, or Welch’s t-test were used. Accepted level of ...
