。结论 加速度二次积分算法能够有效解决胸外按压深度测量难题,在心肺复苏训练和急救中具有较好的
应用价值。

Objective To develop a real-time and accurate chest compression depth
measurement for manual and auto chest compression training or treatment,improving the
current ineffective or over-deep chest compressions.Methods This paper presents the depth
measurement of chest compression based on double integration of acceleration.The system
integrates the acceleration measurement module,the pressure peak detection module and the
algorithm of acceleration signals processing.The double integration of acceleration is
based on pressure peak detection,and the chest compression depth is obtained through the
double integration of acceleration signals between minimum point and maximum point of
compression pressure.Results After the chest compression experiments on the Laerdal
Resusci? Anne Basic and SkillGuide and comparative analysis with the data acquired by the
NI DAQ device,the proposed measurement error is less than 5mm.Conclusions Double
integration of acceleration can effectively solve the challenging problem of chest
compression depth measurement and have a good application value in chest compression
training and treatment.
