A cross-sectional, non-experimental research design was adopted, involving an accidental sample of 39 qualified radiographers from two different public hospitals (Hospital A and Hospital B).

Data were collected using a self-applied paper-based questionnaire to evaluate the knowledge of radiographers in relation to adult basic life support guidelines. This questionnaire was an adaptation of the original questionnaire applied by Neves et al (2010) in the study "Physycal therapists knowledge on basic life support" and contains 2 main parts:  1) demographic details, and 2) multiple choise questions regarding recent training and knowledge of adult BLS (4).

Quantitative data was statistically analysed through descriptive statistics, Mann-Whitney and Spearman tests.
