Oximetry

Overall, however, clinical signs are poor predictors of hypoxaemia, and using pulse oximetry in resource-poor health facilities to target oxygen therapy is likely to save costs.

总之，临床症状不能很好地预示低血氧症，在资源匮乏的医疗机构进行脉搏血氧测量并借此判断是否采取吸氧疗法可以节省成本。

Six people use the designed pulse oximetry to measure the oxygen saturation. The test results show that the pulse oximetry has met the design requirements and complete the expected functionality.

采用所设计的脉搏血氧饱和度检测仪对6名受试者进行了血氧饱和度检测试验，结果表明所研制的脉搏血氧仪基本达到设计要求。

In order to simplify the complexity of circuit design and signal noise removal, we use the software method to pretreat and compute pulse oximetry signal and the temperature signal.

为了简化复杂的电路设计和去除信号中噪声干扰，本文采用软件方法实现脉搏血氧信号和温度信号的预处理以及值的计算。
