Extending the capabilities of mobile device based pulse oximetry

移动医疗（mHealth）是指使用移动电话来提高医疗质量和效率。在拥有70亿人口和68亿部手机的世界上，移动医疗是筛查和提供医疗服务的重要途径。我们来自UBC的团队创造了一种创新的移动医疗解决方案，称为手机血氧仪，它使用手机应用程序和手指传感器来测量血氧饱和度。血氧饱和度是一项重要的生命体征，通过将其与几个简单问题的答案相结合，我们可以帮助诊断和监测患者，并为资源贫乏的医疗保健提供者提供决策支持。该解决方案的技术创新在于将生物医学工程和医学生理学的复杂原理应用于创造一种低成本，准确和有效的设备，该设备易于在现场使用，只需最少的培训和维护。

Mobile Health (mHealth) refers to the use of mobile phones to improve healthcare quality and efficiency. In a world of 7 billion people and 6.8 billion mobile phones, mHealth represents a remarkable avenue for screening and care delivery. Our team from UBC has created an innovative mHealth solution called the Phone Oximeter, which uses a phone app and a finger sensor to measure blood oxygen saturation. Blood oxygen saturation is an important vital sign and by combining it with answers to a few simple questions we can help diagnose and monitor patients, and provide decision-making support to healthcare providers in resource-poor settings. The technical innovation of this solution is in the application of complex principles of biomedical engineering and medical physiology to the creation of a low-cost, accurate and effective device that is easy to use in the field with minimal training and maintenance.
