摘要

本研究从计算机断层扫描（CT）图像中分割出 18 根肋骨（8 男 10 女）。为了分析心肺复苏（CPR）过程中胸廓生物力学的潜在差异，研究人员使用有限元（FE）进行了一组数值实验。在肋骨上的不同点施加压缩力。结果表明，两性的最佳压迫区域都是第 5 肋骨水平的胸骨，需要最小的力来达到所需的压迫深度。男性比女性需要更大的力量。在女性中，宽度/深度比值较低（胸廓形状更圆）的女性所需的力量小于宽度/深度比值较高（胸廓形状更椭圆）的女性。

Gender-Based Differences in the Biomechanical Behavior of the Thorax During CPR Maneuvers.

In this study, 18 rib cages (8 males and 10 females) were segmented from computer tomography (CT) images. In order to analyze the potential differences in thoracic biomechanics during cardiopulmonary resuscitation (CPR), a set of numerical experiments was conducted using finite elements (FE). Compression forces were applied at different points on the rib cage. Results indicated that the optimal compression area for both sexes is the sternum at the 5th rib level, requiring the least force to achieve the desired compression depth. Males required greater force than females. Among females, those with lower width/depth ratios (more rounded thoracic shape) required less force compared to those with higher ratios (more oval-shaped thorax).

期刊介绍： All differential equation based models for biomedical applications and their novel solutions (using either established numerical methods such as finite difference, finite element and finite volume methods or new numerical methods) are within the scope of this journal. Manuscripts with experimental and analytical themes are also welcome if a component of the paper deals with numerical methods. Special cases that may not involve differential equations such as image processing, meshing and artificial intelligence are within the scope. Any research that is broadly linked to the wellbeing of the human body, either directly or indirectly, is also within the scope of this journal.
