Obesity has emerged as a global health challenge, contributing not only to chronic disease but also to poorer outcomes in acute, high-acuity situations such as cardiac arrest. In the in-hospital setting, obesity poses additional barriers to effective resuscitation, including reduced chest wall compliance, altered thoracic anatomy, and difficulty delivering adequate manual compressions; all of which have been implicated in lower quality cardiopulmonary resuscitation (CPR) [1]. Mechanical chest compression devices, such as the Lund University Cardiopulmonary Assist System (LUCAS®), were designed to overcome these limitations by providing automated, depth- and rate-consistent compressions with active decompression [2,3].
