摘要
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 significance was alpha = 0.05.
Results: Statistically significant greater depth of chest compressions in group A was observed in the first minute of resuscitation with the device versus the first minute without the device. Significant differences in compressions rate between attempts with and without the device were observed in both groups in the first and fourth minute.
Conclusion: Only the group of paramedics showed in time some benefits of the device related to the depth, whereas for the group of non-paramedics, the device seemed to have even a deleterious effect. The group of paramedics met the 2015 recommendations related to compressions rate all the time, while the non-paramedics only in the fourth minute of the procedure.
