Physical activity and quality of cardiopulmonary resuscitation: A secondary analysis of the MANI-CPR trial

Introduction: The association between the level of physical activity and quality of cardio-pulmonary resuscitation (CPR) performed by laypeople is unclear.The aim of this study was to evaluate the associations between physical activity level and laypeople performance during an eight-minute scenario of CPR. Materials and methods: This study was a secondary analysis of the MANI-CPR Trial. The entire cohort of participants was grouped based on the level of physical activity assessed using the International Physical Activity Questionnaire (IPAQ) into a low-moderate" level group and a "high" level group. Descriptive statistics were used for unadjusted analysis and multivariate logistic and linear regression models were also performed. Results: A total of 492 participants who reached the score of "Advanced CPR performer" at the 1-min final test monitored by Laerdal Resusci Anne QCPR were induded in this analysis; 224 with a low-moderate level and 268 with a high level of physical activity. A statistically significant difference was found for the outcome of percentage of compressions with adequate depth (low-moderate group: 87.8% [41.4%-99.3%], high group: 97% [63.2%-100%]; P = 0-003). No associations remained significant after controlling for biometric characteristics of the participants, compression protocols and sex. Conclusion: Adequate quality CPR may not need high baseline level of physical activity to be performed by a lay rescuer. (C) 2021 Elsevier Inc. All rights reserved.
