Abstract
To analyze the factors associated with the knowledge of lay people about basic life support. This is a descriptive cross-sectional epidemiological study, conducted with 65 employees from a Campus at the State University of Bahia. Data were collected in February and March 2019 and tabulated in IBM SPSS version 21.0 software. The analysis was performed using descriptive frequencies, Pearson's chi-square test and Fisher's exact test, adopting a significance level of 95% and p value <0.05. It was observed that 67.7% of participants do not know what is basic life support, 61.5% do not feel prepared to act in emergency, 58.5% would not know how to facilitate the breathing of a victim, 64.7% do not know the amount of compressions performed per minute and 86.2% do not know the function of the automatic external defibrillator. Regarding associated factors, knowledge about basic support is associated with being a teacher (p = 0.005), feeling prepared to act in emergency situations (p = 0.001), knowing how to facilitate the victim's breathing (p = 0.001). = 0.000), know the location of the chest compressions (p = 0.013). The study raises the need for greater training of lay people about basic life support so that they can adequately assist victims of cardiac arrest in an out-of-hospital setting.
