    摘要:

    血氧饱和度是临床诊断和家庭保健中常用的重要生理指标。在临床上,尤其在手术过程中,血氧饱和度的高低关系到病人的生命安全,因此常常需要检测人体的血氧饱和度。同时,监测人体血氧饱和度的变化对肺心病的预防和治疗也有重要的作用。因此,血氧饱和度的监测具有重要的意义。为了能够实时准确地显示脉搏波信号和血氧饱和度,文章设计了基于 AFE4400 的血氧饱和度测量系统及开发了相应的 Android 手机应用程序,不仅使其便于使用,同时进一步降低了成本。实验结果显示,设计的系统具有十分高的准确性。

    Abstract:

    The blood oxygen saturation is a very important physiological index in common clinical diagnosis and family care. The patient’s life is related to the level of blood oxygen saturation to some extent, so the oxygen saturation should be detected in the clinical, especially in the operation. Because monitoring the volatility of the blood oxygen saturation plays an important role in the prevention and treatment of the pulmonary heart disease, it has the extremely vital significance. The SpO2 system which we designed is based on AFE4400 and we developed an application of android smartphone in order to display the PPG signal and the blood oxygen saturation timely and exactly. It’s easy to use and makes a further cost reductions. The experimental results show that the system has a very high accuracy.
