It is not understood how cardiopulmonary resuscitation (CPR) training, specifically the representation of sex in CPR manikins, contributes to inequitable outcomes in cardiac arrest survival. The aim of this study was to identify the sex and chest wall secondary sexual characteristics of CPR manikins on the global market. The secondary aim was to identify if manikin manufacturing companies had a publicly available sustainability policy or equivalent, and if these covered products were manufactured. We conducted an observational descriptive study of the secondary sex characteristics and named sex of CPR training manikins available on the global market, and equity, diversity and inclusion (EDI), human rights and sustainability policies of the companies that manufacture them. Nine CPR manikin manufacturers were identified. Twenty CPR manikins were included for analysis. Of the 20 manikins, 75% were identified as male (n = 8, 40%) or no gender specified (n = 7, 35%) and all these had flat torsos—one had a breast overlay available. One company had a 2020 sustainability report that addressed EDI for the workforce only, and a 2023 report addresses this for products manufactured. Adult CPR manikins available globally are largely homogenous, flat-chested and do not have secondary sex characteristics or a named sex. One company had a sustainability report that referenced workforce only and has since committed to EDI for products manufactured. We urge CPR training providers and manufacturers to collectively promote a rights-based approach to healthcare aligned with the commercial determinants of health by committing to improving the diversity of CPR training manikins.
