Chronic obstructive pulmonary disease (COPD) is a very common disease all around the world and has become an increasing public health concern to the Chinese medical community. In the past decades, telehealthcare technology has become a good way to manage COPD but current evidence makes it hard to determine the effectiveness of this technology. Internet of things (Iot) is a recent breakthrough in communication technology, which links the virtual world to the real world through connection between sensors and working devices. It relates people and items in any ways so that data collection and management become more flexible. Our review concentrates on the effectiveness and potential application of telehealthcare in COPD management and how IoT technology may stimulate COPD healthcare delivery through telehealthcare technology.
