Abstract
Background: Cardiopulmonary arrest (CPA) is a severe public health problem and a leading cause of death worldwide. According to the American Heart Association (AHA), basic life support (BLS) is the bedrock for improving people's survival after a cardiac arrest, and cardiopulmonary resuscitation is crucial. Through scientific evidence, empowering health professionals focuses on education in resuscitation is vital to identify and attend a CPA victim. In Brazil, there is a lack of data that evaluates the BLS knowledge of health science students. This study analyzed the knowledge retention of medicine, nursing, and physiotherapy students after one year of having a lecture-demonstration on BLS. Method: Longitudinal study. Undergraduate students of health science participated in the data collection and answered a questionnaire based on BLS following AHA guidelines. Data were collected during two consecutive years, in three different moments (an assessment, a test after a lecture, and an assessment test one year later). Results: The group improved its score after the class on BLS; the number of correct answers doubled (p <0.001); however, one year later, that score decreased significantly (p <0.001). Conclusion: No retention of knowledge in health sciences students after a year of a lecture-demonstration on BLS.

What do these findings mean? The results show the importance of practicing cardiopulmonary resuscitation (CPR) in basic life support training to improve knowledge retention
Summary
Cardiac arrest (CA) is a severe public health problem and a leading cause of death worldwide[1,2], accounting for approximately 15% to 20% of all deaths. Cardiopulmonary resuscitation (CPR) rates are generally improving worldwide, most individuals who experience sudden cardiac arrest out of hospital do not receive appropriate CPR and will not survive[3]. Future health professionals’ qualifications and ideal performance depend on the cognitive, behavioral, and psychomotor skills needed to perform CPR successfully[4]. There is a need for health professionals to achieve high-quality CPR5, and that there is a knowledge and skill retention problem for them in being able to do this[4,6,7,8,9]. Despite ongoing advances in prevention and resuscitation science, cardiac arrest survival rates remain below ideal for in-hospital and outof-hospital CA5
