Quality and features of tele-homecare are improved by information and communication technologies. In this context, a pulse oximeter-based mobile biotelemetry application is developed. With this application, patients can measure own oxygen saturation and heart rate through Bluetooth pulse oximeter at home. Bluetooth virtual serial port protocol is used to send the test results from pulse oximeter to the smart phone. These data are converted into XML type and transmitted to remote web server database via smart phone. In transmission of data, GPRS, WLAN or 3G can be used. The rule based algorithm is used in the decision making process. By default, the threshold value of oxygen saturation is 80; the heart rate threshold values are 40 and 150 respectively. If the patient's heart rate is out of the threshold values or the oxygen saturation is below the threshold value, an emergency SMS is sent to the doctor. By this way, the directing of an ambulance to the patient can be performed by doctor. The doctor for different patients can change these threshold values. The conversion of the result of the evaluated data to SMS XML template is done on the web server. Another important component of the application is web-based monitoring of pulse oximeter data. The web page provides access to of all patient data, so the doctors can follow their patients and send e-mail related to the evaluation of the disease. In addition, patients can follow own data on this page. Eight patients have become part of the procedure. It is believed that developed application will facilitate pulse oximeter-based measurement from anywhere and at anytime.
信息和通信技术提升了远程家庭护理的质量与功能。在此背景下，开发了一款基于脉搏血氧仪的移动生物遥测应用程序。通过该应用程序，患者在家中可使用蓝牙脉搏血氧仪测量自己的血氧饱和度和心率。蓝牙虚拟串口协议用于将脉搏血氧仪的测试结果发送至智能手机。这些数据被转换为XML格式，并通过智能手机传输至远程网络服务器数据库。在数据传输过程中，可使用GPRS、WLAN或3G。决策过程采用基于规则的算法。默认情况下，血氧饱和度阈值为80；心率阈值分别为40和150。若患者心率超出阈值范围或血氧饱和度低于阈值，将向医生发送紧急短信。通过这种方式，医生可指挥救护车前往患者处。针对不同患者，医生可更改这些阈值。评估数据结果到短信XML模板的转换在网络服务器上完成。该应用程序的另一个重要组件是基于网络的脉搏血氧仪数据监测。网页可提供所有患者数据的访问权限，因此医生能够跟踪其患者并发送与疾病评估相关的电子邮件。此外，患者也可在该页面上查看自己的数据。已有八名患者参与了该流程。相信所开发的应用程序将便于随时随地基于脉搏血氧仪进行测量。
