我们表明，一个移动的手机可以作为一个精确的监视器的几个生理变量的基础上，它的能力，记录和分析不同的颜色信号的指尖放置在接触其光学传感器。我们通过与进行此类测量的标准方法（分别为呼吸带、ECG和脉搏血氧仪）进行比较，确认呼吸率、心脏R-R间期和血氧饱和度测量的准确性。呼吸率的测量使用先前报告的算法，该算法基于光信号内的幅度和频率调制序列，开发用于脉搏血氧计。我们注意到，这项技术也可以与最近开发的用于检测房颤或失血的算法一起使用。
We show that a mobile phone can serve as an accurate monitor for several physiological variables, based on its ability to record and analyze the varying color signals of a fingertip placed in contact with its optical sensor. We confirm the accuracy of measurements of breathing rate, cardiac R-R intervals, and blood oxygen saturation, by comparisons to standard methods for making such measurements (respiration belts, ECGs, and pulse-oximeters, respectively). Measurement of respiratory rate uses a previously reported algorithm developed for use with a pulse-oximeter, based on amplitude and frequency modulation sequences within the light signal. We note that this technology can also be used with recently developed algorithms for detection of atrial fibrillation or blood loss.
